37. The expert from China introduced ECE/TRANS/WP.29/GRE/2012/35 and GRE-68-35, proposing to improve the resistance test of lens material to atmospheric agents.

The expert from SAE provided the secretariat with written comments after the meeting (GRE-68-41) to the proposals tabled by the expert from China.
