Proposal to clarify under para. 2.2.3 the conditions under which multiple exhaust versions’ results may be listed on a single R41 approval certificate. The current text may be strictly interpreted as requiring separate certification for every possible configuration, such as differences in exhaust systems, intakes or engine displacements. The proposal aims to improve efficiency and effectiveness of type approval procedures.
