11. The expert from France introduced ECE/TRANS/WP.29/GRSG/2022/3 to clarify the classification of panes in “safety-glass faced with plastics material” and “glass-plastics”, and ECE/TRANS/WP.29/GRSG/2022/4 to resolve a potential inconsistency in abrasion test requirements for flexible plastics other than the windscreen.

12. GRSG adopted ECE/TRANS/WP.29/GRSG/2022/3 and ECE/TRANS/WP.29/GRSG/2022/4, not amended. The secretariat was requested to combine the two documents for submission as a unique proposal of Supplement 10 to the 01 series of amendment to UN Regulation No. 43 (Safety glazing), for consideration and vote at the November 2022 sessions of WP.29 and AC.1.

13. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2022/5 to clarify the current definition of security glazing in UN Regulation No. 43. However, this does not pertain to the category of T vehicles – wheeled or tracked agricultural or forestry vehicles – which require a security glazing windscreen to protect the occupant from, for example, ruptured chainsaws (required in ISO 21876:2020).

14. GRSG noted that the current provisions of the UN Regulation did not allow type approval of the safety glazing of T vehicles. GRSG agreed to postpone full discussion of ECE/TRANS/WP.29/GRSG/2022/5 to its October 2022 session, while awaiting a full understanding of the solutions to test configurations of safety glazing of the T vehicle category that were coordinated by the experts from OICA, CLCCR and other interested parties.
