7.4.3. The IWVTA type is affected but the manufacturer does not want to maintain the universal status of the IWVTA. In that case, the U-IWVTA shall be withdrawn (effective at the date the IWVTA ceases to be universal). For the continued production a new L-IWVTA shall be issued. However, when granting this new L-IWVTA, transitional provisions of UN Regulation No. 0 and UN Regulations listed in Annex 4 shall be interpreted as if an existing IWVTA were extended. a0c0
