The expert from Belgium introduced (GRSP-62-04) aiming at establishing a more appropriate frequency for inspection and random sampling indicated in Annex 12 to the UN Regulation to ensure an effective control of the conformity of production. GRSP noted GRSP-62-10 on preventing the use of a Unique Identifier, since in the case of the UN Regulation No. 22 on handling protective helmets and their visors, the approval number carried particular information that were relevant for users and enforcement controls. GRSP also noted that the same provisions had already been introduced for Child Restraint Systems in UN Regulations Nos. 44 and 129. Finally, GRSP adopted GRSP-62-04 and GRSP-62-10 as reproduced in Annex V to the report. The secretariat was requested to submit both proposals for consideration and vote to the June 2018 sessions of WP.29 and AC.1 as draft Supplement 3 to the 05 series of amendments to UN Regulation No. 22.
