Proposer's reason (informal document GRSG-124-32)
According to the proposal, all series of UN Regulation No. 110 but the 04 series contain a transitional provision of this kind. This provision accepts the type approvals according to the preceding series when the new series does not affect them. The proposal lists paragraph 24.3 (01 series), 24.13 (02 series), 24.20 (03 series) and 24.30 (05 series). It says that such a provision is needed also for the 04 series because the 04 series is still in force.
Submitted by Experts of NGVA Europe. Working party adoption: ECE/TRANS/WP.29/GRSG/103, para. 21.
