Proposal to revise provisions and formulas in GTR 22 Annex 3, paras. 2.1.2. and 3.1.2., UN R154-04 Annex C1, Appendix 2, paras. 2.1.2. and 3.1.2., and UN R83-09 Appendix 5, para. 3.1.2. to make UBEcertified values positive and select the maximum absolute value. The document EVE-63-11e addresses concerns that when the interpolation method is applied under GTR No. 15 / UN R154, UBEcertified values become negative, contrary to regulatory intent. Revisions ensure UBEcertified is determined by selecting the maximum absolute value amongst vehicle H, vehicle L, and vehicle M where applicable.
The agenda addresses UN GTR 22, UN GTR 21, and UN GTR 25, with discussions on fuel cell vehicle proposals, open items, verification results, alternative test methods, and battery replacement provisions. A reminder notes that UN GTR 25 amendment 2 must be submitted to GRPE-96 by December 2026.
