Vehicles of categories L, M, N and O [1] with regard to electromagnetic compatibility;

Components and separate technical units intended to be fitted in these vehicles with the limitation given in paragraph 3.2.1. with regard to electromagnetic compatibility.

As defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3), document ECE/TRANS/WP.29/78/Rev.3, para. 2.

"Electromagnetic immunity" means the ability of a vehicle or component(s) or separate technical unit(s) to operate without degradation of performance in the presence of (specified) electromagnetic disturbances which includes wanted radio frequency signals from radio transmitters or radiated in-band emissions of industrial-scientific-medical (ISM) apparatus, internal or external to the vehicle.

"Electrical/electronic sub-assembly" (ESA) means an electrical and/or electronic device or set(s) of devices intended to be part of a vehicle, together with any associated electrical connections and wiring, which performs one or more specialized functions. An ESA may be approved at the request of a manufacturer or his authorized representative as either a "component" or a "separate technical unit (STU)".

(i) Optical disturbances: incorrect operation of e.g. direction indicators, stop lamps, end outline marker lamps, rear position lamp, light bars for emergency system, wrong information from warning indicators, lamps or displays related to functions in subparagraphs (a) or (b) which might be observed in the direct view of the driver;

The vehicle manufacturer shall draw up a schedule describing all relevant vehicle electrical/electronic systems or ESAs, body styles, variations in body material, general wiring arrangements, engine variations, left-hand/right-hand drive versions and wheelbase versions. Relevant vehicle electrical/electronic systems or ESAs are those which may emit significant broadband or narrowband radiation and/or those which are involved in immunity related functions of the vehicle (see paragraph 2.12.) and those which provide coupling systems for charging the REESS.

If the Technical Service responsible for the type approval test carries out the test itself, then a vehicle representative of the type to be approved according to paragraph 3.1.4. above shall be provided.

If the Technical Service responsible for the type approval test carries out the test itself, then a sample of the ESA system representative of the type to be approved shall be provided, if necessary, after discussion with the manufacturer on, e.g. possible variations in the layout, number of components, number of sensors. If the Technical Service deems it necessary, it may select a further sample.

ESA which are brought to the market as spare parts need no type approval if they are obviously marked as a spare part by an identification number and if they are identical and from the same manufacturer as the corresponding Original Equipment Manufacturer (OEM) part for an already type approved vehicle.

A model of communication form for type approval is contained in Annex 3A.

In order to draw up the communication forms referred to in paragraph 4.2.1.2. or 4.2.2.2. above, the Type Approval Authority of the Contracting Party granting the approval may use a report prepared or approved by a recognized laboratory or in accordance with the provisions of this Regulation.

An approval mark described in paragraph 5.3. below shall be affixed to every vehicle conforming to a type approved under this Regulation.

An approval mark described in paragraph 5.3. below shall be affixed to every ESA conforming to a type approved under this Regulation.

At a height of 1.0 ± 0.05 m above the plane on which the vehicle rests or 2.0 ± 0.05 m if the minimum height of the roof of any vehicle in the model range exceeds 3.0 m,

Either at 1.0 ± 0.2 m behind the vertical centreline of the vehicle's front wheel (point C in Figure 1 of Appendix 1 to this annex) in the case of three-wheeled vehicles,

Or at 0.2 ± 0.2 m behind the vertical centreline of the vehicle's front wheel (point D in Figure 2 of Appendix 1 to this annex) in the case of two-wheeled vehicles.

If it is decided to radiate the rear of the vehicle, the reference point shall be established as in paragraphs 3.3.1. to 3.3.4. above. The vehicle shall then be installed facing away from the antenna and positioned as if it had been horizontally rotated 180 around its centre point, i.e. such that the distance from the antenna to the nearest part of the outer body of the vehicle remains the same. This is illustrated in Figure 3 of Appendix 1 to this annex.

The vehicle shall be exposed to electromagnetic radiation in the 20 to 2,000 MHz frequency ranges in vertical polarization.

(b) PM (pulse modulation), Ton 577 µs, period 4,600 µs in the 800 to 2,000 MHz frequency range,

Frequency step size and dwell time shall be chosen according to ISO 11451-1.

The Technical Service shall perform the test at the intervals specified in ISO 11451-1 throughout the frequency range 20 to 2,000 MHz.

The vehicle shall be positioned with the centre line of the vehicle on the facility reference point or line. The vehicle shall normally face a fixed antenna. However, where the electronic control units and the associated wiring harness are predominantly in the rear of the vehicle, the test should normally be carried out with the vehicle facing away from the antenna. In the case of long vehicles (i.e. excluding vehicles of categories L, M1 and N1), which have electronic control units and associated wiring harness predominantly towards the middle of the vehicle, a reference point may be established based on either the right side surface or the left side surface of the vehicle. This reference point shall be at the midpoint of the vehicle's length or at one point along the side of the vehicle chosen by the manufacturer in conjunction with the Type Approval Authority after considering the distribution of electronic systems and the layout of any wiring harness.

Unless otherwise specified the length of the Low Voltage (LV) harness and the HV harness parallel to the front edge of the ground plane shall be 1,500 mm (±75 mm). The total length of the test harness including the connector shall be 1,700 mm (+300/-0 mm). The distance between the LV harness and the HV harness shall be 100 mm (+100/-0 mm).

All of the harnesses shall be placed on a non-conductive, low relative permittivity material (εr ≤ 1.4), at 50 mm (±5 mm) above the ground plane.

The phase centre of the antenna shall be in line with the centre of the longitudinal part of the wiring harnesses for frequencies up to 1,000 MHz.

The Technical Service shall perform the test at the intervals specified in the CISPR 12 standard throughout the frequency range 30 to 1,000 MHz.

Alternatively, if the manufacturer provides measurement to data for the whole frequency band from a test laboratory accredited to the applicable parts of ISO 17025 and recognized by the Type Approval Authority, the Technical Service may divide the frequency range in 14 frequency bands 30– 34, 34–45, 45–60, 60–80, 80–100, 100–130, 130–170, 170–225, 225–300, 300–400, 400–525, 525–700, 700–850 and 850– 1,000 MHz and perform tests at the 14 frequencies giving the highest emission levels within each band to confirm that the ESA meets the requirements of this annex.

In the event that the limit is exceeded during the test, investigations shall be made to ensure that this is due to the ESA and not to background radiation including broadband radiation from the ESA.
