Document title UN Regulation No. 90 approval numbers and certification issue
Date 18 Sep 2014

For testing purposes, UN R90 defines a “test group” as a grouping of parts having the same characteristics. The regulation then defines a “variant” as a part within a “test group”. However, the approval numbers under the rule stipulate the identification of each variant certified. As a result, the text technically requires certification of each individual part (variant) which was not the intention of the drafters. CLEPA raises this for information purposes with the intention to put forward a proposal at the next GRRF session.
