20. The expert of FEMFM introduced GRRF-73-04 taking into account some remarks received during the last session of GRRF. He recalled the purpose of the proposal and underlined that so called “chemically and physically identical replacement brake lining assemblies” and “chemically and physically identical drum brake linings” should not have to be tested but should be approved on the basis of the homologation of the original equipment supplier. In that case, the applicants for approval should only demonstrate that they supply the brake lining assemblies or the drum brake linings for the vehicle or brake manufacturer as original equipment for the specific model/models for which approval is being sought, and that they produce the parts under the same production conditions, quality assurance system, and with the same results of the conformity of production tests as for the original parts.

21. The expert of Spain reported some weaknesses in a similar case (for discs and drums), where this type of provision was already in force. Based on this experience, he underlined the need to be precise. He added, the goal is to make sure that only original manufacturers can use this procedure. GRRF reviewed the wording of the informal document and the expert of FEMFM invited GRRF to send him any further contributions to allow him to submit in due time an updated wording in the form of an official document for consideration at the next session of GRRF.
