Editorial clarification of the proposed transitional provision from the WP.29 secretariat..

Pursuant to GRPE work on vehicle propulsion system definitions (VPSD informal group; see document WP.29-165-17), this proposal would update the definition of the acronym “REESS” to refer to “rechargeable electrical energy storage system” across the passive safety regulations and currently proposed texts that make use of this acronym. (REESS had previously referred generically to “rechargeable energy storage systems”.)

Text prepared by the Informal Working Group on Frontal Impact (IWG FI) as an outcome of discussions of the Working Party on Passive Safety (GRSP) at its fifty-seventh session on developing a separate new Regulation on frontal impact focusing on requirements for restraint systems.
