... Introduction a0c0
... This Regulation combines the provisions of individual UN Regulations Nos. 3, 27, 69, 70 and 104 into a single UN Regulation, and is the outcome of the World Forum for Harmonization of Vehicle Regulations (WP.29) decision to simplify the lighting and light-signalling Regulations based on the initial proposal by the European Union and Japan. a0c0
... The objective of this Regulation is to increase the clarity, to consolidate and streamline the complexity of requirements in UN Regulations Nos. 3, 27, 69, 70 and 104 and to prepare for the future transition to performance based requirements, by reducing the number of UN Regulations through an editorial exercise without changing any of the detailed technical requirements already in force up to the date of entry into force of this Regulation. a0c0
... Although this Regulation departs from the traditional approach of having a separate Regulation for each retro-reflective device, by combining all retro-reflectors retro-reflective marking plates, retro-reflective markings and advance warning triangles into a single Regulation, this simplified UN Regulation contains all provisions and operates according to the existing structure of series of amendments, their transitional provisions and supplements. The transitional provisions associated with a new series of amendments to this Regulation will be identified for each device as applicable, this also includes a list of devices and their applicable change indexes relating to the series of amendments. a0c0
... It is expected that all Contracting Parties to the 1958 Agreement will adopt this Regulation and will provide detailed explanation in case they are not in a position to adopt particular retro-reflective devices. These decisions will be registered in ECE/TRANS/WP.29/343 that records the status of the annexed UN Regulations and of the amendments. a0c0
... Regarding the requirements for approval markings, this Regulation includes the requirements for the use of the "Unique Identifier" and is conditional upon access to a secure internet database established by UNECE (in accordance with Schedule 5 of the 1958 Agreement) where all type approval documentation is held. When the "Unique Identifier" is used there is no requirement for retro-reflective devices to carry the conventional type approval markings (E-mark). If it is technically not possible to use the "Unique Identifier" (e.g. if the access to the UN internet database cannot be secured or the UN secure internet database is not operative) the use of conventional type approval markings is required until the use of the "Unique Identifier" is enabled. a0c0

2.1.1. "Retro-reflective devices of different types" means retro-reflective devices, as retro-reflectors or retro-reflective materials or marking plates or advance warning triangles of different types, which differ in such essential respects as: a0c0
... (a) The trade name or mark: a0c0
... (i) Retro-reflective devices bearing the same trade name or mark but produced by different manufacturers are considered as being of different types; a0c0
... (ii) Retro-reflective devices produced by the same manufacturer differing only by the trade name or mark are considered as being of the same type; a0c0
... (b) The characteristics of the retro-reflective material; a0c0
... (c) The characteristics of the fluorescent material, if applicable; a0c0
... (d) The parts affecting the properties of the retro-reflective materials and/or plates; a0c0
... (e) The distinctive geometrical and mechanical features of the design (only for plates/devices corresponding to the Annex 5. a0c0
... For materials and/or plates corresponding to the Annex 5, differences in the shape and dimensions of the marking shall not constitute a different type. a0c0
2.1.2. In the case of a type of "retro-reflective device" or reflective marking material differing only by the trade name or mark from a type that has already been approved it shall be sufficient to submit: a0c0
... (a) A declaration by the "retro-reflective device" or reflective marking material manufacturer that the type submitted is identical with (except in the trade name or mark) and has been produced by the same manufacturer as the type already approved, the latter being identified by its approval number; a0c0
... (b) Two samples bearing the new trade name or mark or equivalent documentation. a0c0
2.2. A type of "retro-reflective device" or retro-reflective material is defined by the models and descriptive literature submitted with the application for approval. Retro-reflective devices can be considered as belonging to the same type if they have one or more "retro-reflecting optical units" which are identical with those of the standard model, or if not identical are symmetrical and suitable for mounting one on the left and one on the right side of the vehicle, and if their other parts differ from those of the standard model only in ways not affecting the properties to which this Regulation applies. A change of colour of the retro-reflective materials of the Classes "D" and "E" does not constitute a change of type. a0c0

A4  Annex 4 a0c0
A4  Photometric measurements of retro-reflective devices and marking materials a0c0
A4 1. Test procedures a0c0
A4 1.1. When the CIL of a retro-reflective device is measured for an angle β of V = H = 0°, it shall be ascertained whether any mirror effect is produced by slightly turning the device. If there is any such effect, a reading shall be taken with an angle β of V = ± 5°, H = 0°. The position adopted shall be that corresponding to the minimum CIL for one of these positions. a0c0
A4 1.2. With an illumination angle β of V = H = 0°, or the angle specified in paragraph 5. of this Regulation, and an angle of divergence of 20', retro-reflective devices which are not marked "TOP" shall be rotated about their axes of reference to the position of minimum CIL, which must conform to the value specified in paragraph 5. of this Regulation. When the CIL is measured for the other angles of illumination and divergence, the retro-reflective device shall be placed in the position corresponding to this value of ε. If the specified values are not attained, the device may be rotated about its axis of reference ± 5° from that position. a0c0
A4 1.3. With an illumination angle β of V = H = 0°, or the angle specified in paragraph 4. of this Regulation, and an angle of divergence of 20', retro-reflective devices marked "TOP" shall be rotated about their axes ± 5°. The CIL must not fall below the prescribed value in any position assumed by the device during this rotation. a0c0
A4 1.4 If for the direction V = H = 0°, and for ε = 0° the CIL exceeds the specified value by 50 per cent or more, all measurements for all angles of illumination and divergence shall be made for ε = 0°. a0c0
A4 2. Definitions a0c0
A4  The definitions are explained by Figures A4-I to A4-V. a0c0
A4 3. Dimensional and physical specifications for the photometry of retro-reflective devices a0c0
A4 3.1. The CIE-angular system as shown in Figure A4-I shall be used. a0c0
A4  An adequate support (goniometer) is demonstrated in Figure A4-II. a0c0
A4 3.2. For testing the retro-reflection the retro-reflective devices shall be illuminated with a CIE Standard Illuminant A (ISO 11664-2:2007(E)/CIE S 014-2/E:2006) and measured as described in Annex 4. a0c0
A4 3.3. The measuring geometry is described in Figure A4-I and the following limits are set up: a0c0
A4  Angular diameter of the source - δ ≤ 10' a0c0
A4  Angular diameter of the measuring device - γ ≤ 10' a0c0
A4  Angular diameter of the illuminated area - η ≤ 80' a0c0
A4 3.4. During photometric measurements, stray reflections should be avoided by appropriate masking. a0c0
A4 3.5. The measuring distance shall be chosen in such an order that at least the limits for the angles δ, γ and η given in Figure A4-IV are respected, but not lower than 10 m or its optical equivalent. a0c0
A4  The retro-reflection values shall be determined by means of a measuring geometry as described above with the retro-reflecting device set up to a distance of at least 10m forward of the centre of reference of each retro-reflecting device perpendicular to the measurement axis from the origin of the gonio(photo)meter system. a0c0
A4 3.6. The illuminance at the retro-reflective device a0c0
A4  The illuminance over the useful area of the retro-reflective device, measured perpendicular to the incident light shall be sufficiently uniform. A check on this condition requires a measuring element, the sensitive area of which is not greater than one-tenth of the area to be examined. The variation in the value of the illuminance shall then comply with the condition: a0c0
A4  a0c0
A4 3.7. The colour temperature and the spectral distribution of the source a0c0
A4  The source used for illuminating the retro-reflective device shall as faithfully as possible represent the CIE Illuminant A, both as regards colour temperature and spectral power distribution. a0c0
A4 3.8. The photometer head (measuring element) a0c0
A4 3.8.1. The photometer head shall be corrected to the spectral luminous efficiency for the CIE standard photometric observer in photopic vision. a0c0
A4 3.8.2. The device shall not show a perceptible change in local sensitivity within the area of its aperture; otherwise suitable provisions shall be added, e.g. the application of a diffusing window at a certain distance in front of the sensitive surface. a0c0
A4 3.8.3. Experience has shown that non-linearity of photometer heads may be a problem with the very small light quantities which are the rule in the photometry of retro-reflective devices. A check at comparable illuminance levels on the photometer head is recommended. a0c0
A4 3.9. The influence of a regular reflection a0c0
A4  The amount and distribution of the regular reflection from the surface of the retro-reflector depends on the flatness and the gloss of the surface. In general, regular reflection is best avoided when the reference axis is placed so that the regular reflection is directed on the opposite side of the source from the photometer head (for example with β1 = -5°). a0c0
A4 4. Measurement precautions in the photometry of retro-reflection a0c0
A4 4.1. Residual and stray light a0c0
A4 4.1.1. Since very low light levels are to be measured special precautions are needed to minimize errors due to stray light. The background to the sample and the framework of the sample holder should be matt black and the field of view of the photometer head and the spread of light from both the sample and the source should each be restricted as much as possible. a0c0
A4 4.1.2. Reflections from the floor and walls which occur over the relatively long test distances used shall be screened from both the sample and the photometer head by baffles. The importance of looking from the photometer head to check for sources of stray light cannot be over emphasized. a0c0
A4 4.1.3. A valuable aid to reducing the amount of stray light in the laboratory is to use a slide projector type of optical system for the light source. With this, an iris diaphragm or suitable sized apertures may be used in the optical system to restrict the illuminated area at the sample to the minimum size needed to provide uniform illuminance over the sample. a0c0
A4 4.1.4. Residual stray light should always be allowed for by measuring it when the sample is covered by an opaque matt black surface, zigzag folded black paper of the same size and shape or a specular black surface suitably oriented with a light trap. This value should be subtracted from that measured on the retro-reflective device a0c0
A4 4.2. Stability of the apparatus a0c0
A4 4.2.1. The light source and photometer head should remain stable throughout the period of the test. Since the sensitivity and the adaptation to the V (λ) function of most photometer heads change with temperature, the laboratory ambient temperature should not vary significantly during this period. Sufficient time should always be allowed for the apparatus to stabilize before commencing measurements. a0c0
A4 4.2.2. The power supply to the light source should be adequately stabilized so that the luminous intensity of the lamp can be maintained throughout the test to within the required accuracy for the work. a0c0
A4 4.2.3. A useful check on the overall stability of the reflex photometer during a series of tests is to make periodic measurements of CIL values of a stable reference standard. a0c0
A4 4.2.4. Another technique is to incorporate in the apparatus an auxiliary detector to check or monitor the output of the light source. Although the output from the auxiliary detector can be checked for any change in reading, a useful refinement is to use the output to alter electronically the sensitivity of the main reflex photometer head and compensate automatically for changes in the light output of the source. a0c0
A4 4.3. Description of Goniometer a0c0
A4  A goniometer as defined in paragraph 2.4. of this Regulation, which can be used in making retro-reflection measurements in the CIE geometry is illustrated in Figure A4-V. In this illustration, the photometer head (O) is arbitrarily shown to be vertically above the source (I). The first axis is shown to be fixed and horizontal and is situated perpendicular to the observation half-plane. Any arrangement of the components which is equivalent to the one shown can be used. a0c0

A20 4.2. Principle of the method a0c0
A20 4.2.1. A known volume V of sand is spread evenly on the surface of the carriageway in the form of a circle. The ratio of the volume used to the area S covered is defined as "mean sand depth" HS and is expressed in mm: a0c0
A20  a0c0
A20 4.2.2. The test is carried out by means of round-grain, dry sand and having a grain size between 0.160 mm and 0.315 mm. The volume amounts to 25 ml ± 0.15 ml. The sand is spread out over the surface where the test is carried out by means of a flat, circular disc with a diameter of 65 mm, one side of which is covered with a sheet of rubber having a thickness of 1.5 mm to 2.5 mm and the other being provided with an appropriate handle. If the diameter of the circular area covered with sand is D mm, the mean sand depth will be calculated in accordance with the formula: a0c0
A20  a0c0
A20 4.3. Performance of the test a0c0
A20 4.3.1. The surface on which the test is to be carried out shall be dry and at first be brushed with a soft brush to remove any dirt or loose gravel. a0c0
A20 4.3.2. The sand which has been firmly filled into an appropriate receptacle is then poured out on the surface to be tested in a single heap. The sand is then carefully spread out on the surface by means of repeated circular movements of the rubber faced disc so as to form the largest possible round area covered with sand. The sand will then fill all depressions and hollows. a0c0
A20 4.3.3. Two diameters, at right angles to one another, of the "beach" thus formed are usually measured. The mean value is rounded off to the nearest 5 mm, with the depth of the sand HS being calculated according to the formula given in paragraph 4.2.2. a0c0
A20 4.3.4. Six tests of this kind are carried out on the supporting surface, with the parts to be tested being distributed over the surface to be tested as evenly as possible. The overall mean of the results obtained is given as the mean sand depth HS of the road surface where the advance warning triangle has been placed. a0c0
A20 5. Test of stability against wind a0c0
A20 5.1. The advance warning triangle shall be set up in a wind tunnel, on a base measuring about 1.50 m by 1.20 m with a surface formed of abrasive material of the type P36 corresponding to the FEPA** specification 43-1-2006. This surface shall be characterised by its geometric roughness, HS = 0.5 mm ± 0.05 mm, which shall be defined and determined by the so-called "sandy beach" method according to Annex 4 of this Regulation. a0c0
A20  To avoid a laminar boundary layer of the incident flow over the surface of the base, this base shall have a splitter plate and shall be set up in such a way, that the flow is completely around the plate. a0c0
A20 5.2. For the air flow the following conditions shall apply: a0c0
A20  (a) The air stream shall reach a dynamic pressure of 180 Pa; and shall have a flow field which shall be homogeneous and free of turbulence; a0c0
A20  (b) The dimension of the flow field shall be such, that horizontally to each corner and vertical to the top of the advance warning triangle a clearance of at least 150 mm to the border line of this flow field shall exist; a0c0
A20  (c) The air stream (flow field) shall be parallel to the supporting surface, in a direction which seems to be most unfavourable for the stability; a0c0
A20  (d) In the case of a closed wind tunnel, the area of the advance warning triangle shall be not larger than 5 per cent of the area cross-section of the closed wind tunnel. a0c0
A20 5.3. When set up in this manner, the advance warning triangle shall be subjected for 3 minutes to this open-air stream. a0c0
A20 5.4. The advance warning triangle shall neither overturn nor shift. Slight shifting of the points of contact with the road surface by not more than 5 cm, however, shall be allowed. a0c0
A20 5.5. The retro-reflecting triangular part of the device shall not rotate through more than 10° round a horizontal axis or a vertical axis from its initial position. The rotation around the horizontal axis or the vertical axis shall be determined by the aid of a virtual plane at the initial position of the retro-reflecting triangular part of the device, which is orthogonal to the base and orthogonal to the air stream. a0c0

A22  Colour fastness to artificial light - Xenon-arc lamp test a0c0
A22 1. Scope a0c0
A22  This annex specifies a method intended for determining the resistance of the colour of test samples of all kinds and in all forms to the action of an artificial light source representative of natural daylight (D65). a0c0
A22 2. Principle a0c0
A22  A specimen of the test samples to be tested is exposed to artificial light under prescribed conditions, along with a blue wool reference as specified. a0c0
A22 3. Reference materials a0c0
A22  The colour fastness ratings mentioned in this annex are obtained by comparison unexposed with exposed specified blue wool references for verification of the radiation dose as a required maximum contrast in this UN Regulation. a0c0
A22 3.1. Blue wool references developed and produced in Europe are identified by the numerical designation 1 to 8. These references are blue wool cloths dyed with the dyes listed in Table A22-1. For the test procedure of this Regulation described by this annex only the blue wool references 5 and 7 will be applied as described in Table A22-1. a0c0

A22 4. Grey scale a0c0
A22  The grey scale for determining changes in colour of test samples in colour fastness tests. A precise colorimetric specification of the scale is given in Appendix 1 to this annex. a0c0
A22 4.1. The use of the scale is described in paragraph 2. of Appendix 1 to this annex. a0c0
A22 5. Xenon-arc lamp apparatus a0c0
A22  The apparatus shall be either an air-cooled or water-cooled Xenon-arc weathering device capable of exposing samples in accordance with EN ISO 4892-2. a0c0
A22 5.1. The exposure conditions shall comply with the requirements in the Table A22-2. a0c0
A22  Table A22-2 a0c0
A22  Artificial weathering test parameters a0c0
A22  a0c0
A22  Note 1: Water used for the specimen spray should contain no more than 1 ppm silica. Higher levels of silica can produce spotting on samples and variability in results. Water of the required purity can be obtained by distillation or by a combination of deionization and reverse osmosis. a0c0
A22  Note 2: While irradiance levels should be set at the above levels, variations in filter ages and transmissivity, and in calibration variations, will generally mean that irradiance error will be in the order of ± 10 per cent. a0c0
A22 5.2. Light source a0c0
A22  The light source shall consist of a xenon arc lamp of correlated colour temperature 5500 K to 6500 K, the size of which will depend on the type of apparatus used. The xenon-arc lamp shall use filters that provide a reasonable simulation of solar radiation filtered by typical window glass. Table 3 gives the relative spectral irradiance requirements for the filtered xenon-arc. It is the responsibility of the supplier of the exposure device to provide necessary certification that the filters that they supply for use in the exposure tests described in this standard meets the requirements of Table A22-3. a0c0
A22  Table A22-3 a0c0
A22  Relative spectral irradiance requirements for window glass filters a, b, c, d, e used for the Xenon-arc devices used in this standard. a0c0
A22  a0c0
A22 a Data in Table A22-3 is the irradiance in the given bandpass expressed as a percentage of the total irradiance from 290 nm to 400 nm. To determine whether a specific filter or set of filters for a xenon-arc meets the requirements of Table A22-3, the spectral irradiance from 250 nm to 400 nm must be measured. The total irradiance in each wavelength bandpass is then summed and divided by the total irradiance from 290 nm to 400 nm. a0c0
A22 b The minimum and maximum data in Table A22-3 are based on more than 30 spectral irradiance measurements for water and air-cooled xenon-arcs with window glass filters of various lots and ages. Spectral irradiance data is for filters and xenon-burners within the ageing recommendations of the device manufacturer. As more spectral irradiance data become available, minor changes in the limits are possible. The minimum and maximum data are at least the three sigma limits from the mean for all measurements. a0c0
A22 c The minimum and maximum columns will not necessarily sum to 100 per cent because they represent the minimum and maximum for the data used. For any individual spectral irradiance, the calculated percentage for the bandpasses in Table A22-3 will sum to 100 per cent. For any individual xenon-arc lamp with window glass filters, the calculated percentage in each bandpass must fall within the minimum and maximum limits of Table A22-2. Test results can be expected to differ between exposures using xenon-arc devices in which the spectral irradiance differ by as much as that allowed by the tolerances. Contact the manufacturer of the xenon-arc devices for specific spectral irradiance data for the xenon-arc and filters used. a0c0
A22 d The data from Table 4 in CIE No. 85 plus window glass was determined by multiplying the CIE No. 85, Table 4 data by the spectral transmittance of 3 mm thick window glass (see ISO 11341). These data are target values for xenon-arc with window glass filters. a0c0
A22 e For the CIE 85 Table 4 plus window glass, the UV irradiance from 300 nm to 400 nm is typically about 9 per cent and the visible irradiance (400 nm to 800 nm) is typically about 91 per cent when expressed as a percentage of the total irradiance from 300 nm to 800 nm. The percentages of UV and visible irradiances on samples exposed in xenon arc devices may vary due to the number and reflectance properties of specimens being exposed. a0c0

A22 6. Procedure (blue wool references) a0c0
A22 6.1. Place the test samples mounted on the holders in the apparatus and expose them continuously to weathering following the method described below. a0c0
A22 6.2. At the same time expose the blue wool references mounted on card-board, cover one-third of each. a0c0
A22 6.3. Only one side of the test samples shall be exposed to weathering and light. a0c0
A22 6.4. While the specimens are drying, the air in the test chamber shall not be moistened. a0c0
A22  Note: The actual conditions of the weathering test depend on the kind of test apparatus used. a0c0
A22 6.5. Before mounting the tested specimens for assessment, dry them in air at a temperature not exceeding 60°C. a0c0
A22 6.6. Trim and mount the exposed blue wool reference so that they measure at least 15 mm x 30 mm, one on each side of a portion of the original which has been trimmed to the same size and shape as the specimens. a0c0
A22 6.7. Unexposed samples of original fabric identical to those being tested are required as references for comparison with the specimens during weathering. a0c0
A22  Appendix 1 a0c0
A22  Definition of the Grey Scale a0c0
A22  This section describes the grey scale for determining changes in colour of test samples in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. a0c0
A22 1. The essential, or 5-step, scale consists of five pairs of non-glossy grey colour chips (or swatches of grey cloth), which illustrate the perceived colour differences corresponding to fastness ratings 5, 4, 3, 2 and 1. This essential scale may be augmented by the provision of similar chips or swatches illustrating the perceived colour differences corresponding to the half-step fastness ratings 4-5, 3-4, 2-3 and 1-2, such scales being termed 9-step scales. The first member of each pair is neutral grey in colour and the second member of the pair illustrating fastness rating 5 is identical with the first member. The second members of the remaining pairs are increasingly lighter in colour so that each pair illustrates increasing contrasts or perceived colour differences which are defined colorimetrically. The full colorimetric specification is given below: a0c0
A22 1.1. The chips or swatches shall be neutral grey in colour and shall be measured with a spectrophotometer with the specular component included. The colorimetric data shall be calculated using CIE standard colorimetric system for Illuminant D65; a0c0
A22 1.2. The Y tristimulus value of the first member of each pair shall be 12 ± 1; a0c0
A22 1.3. The second member of each pair shall be such that the colour difference between it and the adjacent first member is as follows. a0c0
A22  Table A22-5 a0c0
A22  CIE-Lab difference in relation to the Fastness grade a0c0
A22  a0c0
A22  Note 1: Bracketed values apply only to the 9-step scale. a0c0
A22  Note 2: Use of the scale: a0c0
A22  Place a piece of the original blue reference and the exposed specimen of it side by side in the same plane and oriented in the same direction. Place the grey scale nearby in the same plane. The surrounding field should be neutral grey colour approximately midway between that illustrating grade 1 and that illustrating grade 2 of the grey scale for assessing change in colour (this is approximately Munsell N5). Illuminate the surfaces with north sky light in the Northern hemisphere, south sky light in the Southern hemisphere, or an equivalent source with an illumination of 600 lx or more. The light should be incident upon the surfaces at approximately 45°, and the direction of viewing approximately perpendicular to the plane of the surfaces. Compare the visual difference between original and exposed blue standard with the differences represented by the grey scale. a0c0
A22  If the 5-step scale is used, the fairness rating of the specimen is that number of the grey scale which has a perceived colour difference equal in magnitude to the perceived colour difference between the original and the treated specimens; if the latter is judged to be nearer the imaginary contrast lying midway between two adjacent pairs than it is to either, the specimen is given an intermediate assessment, for example 4-5 or 2-3. A rating of 5 is given only when there is no perceived difference between the tested specimen and the original material. a0c0
A22  If the 9-step scale is used, the fastness rating of the specimen is that number of the grey scale which has a perceived colour difference nearest in magnitude to the perceived colour difference between the original and the tested specimens. A rating of 5 is given only when there is no perceived difference between the tested specimen and the original material. a0c0
A23  Annex 23 a0c0
A23  Description of the measurement geometry for measurement of the colour and the luminance factor of fluorescent retro-reflective materials a0c0
A23  Micro-prismatic materials show the phenomenon of "flares" or "sparkles" (Note 1), which might influence the measured results unless special precautions are taken. A reference method, using the wider apertures of the CIE 45°a:0° (or 0°:45°a) geometry is introduced in paragraph 12. of Annex 5. a0c0
A23  Ideally, the measurements shall be made using the CIE 45°a:0° (or 0°:45°a), called the forty-five annular / normal geometry (or the normal/ forty-five annular geometry) defined in CIE 15. The measurement area shall be minimum 4.0 cm . a0c0
A23  For this geometry CIE 15 recommends that: a0c0
A23  (a) The sampling aperture be irradiated uniformly from all directions between two circular cones with their axes normal to the sampling aperture and apices at the centre of the sampling aperture, the smaller of the cones having a half angle of 40° and the larger of 50°. a0c0
A23  (b) The receiver uniformly collects and evaluates all radiation reflected within a cone with its axis on the normal to the sampling aperture, apex at the centre of the sampling aperture, and a half angle of 5°. a0c0
A23  The annular geometry can be approximated by the use of a number of light sources in a ring or a number of fibre bundles illuminated by a single source and terminated in a ring to obtain the CIE 45°c:0° (circumferential / normal geometry) (Note 2, Note 3). a0c0
A23  An alternative manner of approximation is to use a single light source, but rotate the sample during measurement with a rotational speed that ensures that a number of revolutions takes place during the exposure time interval for a measurement so that all wavelengths are given equal weight (Note 2, Note 3). a0c0
A23  In addition, the apertures of the light source and the receiver shall have sufficient dimensions in proportion to distances to ensure a reasonable compliance with the above-mentioned recommendations. a0c0
A23  Note 1: "Flares" or "sparkles" are caused by characteristic paths of rays that enter and leave the sheeting surface at different angles. A characteristic path will dominate by raising the luminance factor value significantly and possibly distorting the chromaticity co-ordinates if it is included within narrow beams of illumination and measurement. However, the average contribution to the daylight reflection is normally small. a0c0
A23  Note 2: In practice the recommendations can be approximated only. The important issue is that the annular principle is applied and that illumination and collection occur in directions forming fairly large solid angles, as this will reduce the influence of the above-mentioned "sparkles" of micro-prismatic materials and of other variations with the precise geometry shown by some of these materials. a0c0
A23  Note 3: In spite of such precautions, the practical difficulties of establishing the annular geometry in accordance with the recommendations introduce uncertainty of measurement. a0c0
