Proposal to clarify the testing method for resistance to high temperature in order to address issues raised with testing at high altitudes and to clarify the requirements of Annex 21 (provisions on the installation of safety glazing on vehicles) based on recommendations from the Informal Group on Plastic Glazing (IGPG).
17. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2014/8 proposing an amendment to UN Regulation No. 43 to cope with the difficulties of technical services located at high altitudes when fulfilling the barometric pressure conditions required for the impact test. The expert from CLEPA preferred to adopt an amendment (ECE/TRANS/WP.29/GRSG/2014/9) to the boiling water test procedure. GRSG adopted ECE/TRANS/WP.29/GRSG/2014/9, as reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as draft Supplement 3 to the 01 series of amendments to UN Regulation No. 43.
Annex 3, paragraph 5.1., amend to read:
“5.1. Procedure
Heat to 100 °C +0 °C / -2 °C three samples or three square test pieces …… specified period of time, care being taken to avoid undue thermal shock. The test shall be carried out in an oven if the boiling water temperature is outside the specified tolerance. If samples are cut from windscreens, one edge of each such sample shall be part of an edge of the windscreen.”
20. On behalf of IGPG, the expert from France introduced document ECE/TRANS/WP.29/GRSG/2014/15 proposing new definitions on interior and exterior glazing and updated provisions of Annex 21 on the installation of safety glazing on vehicles. GRSG adopted ECE/TRANS/WP.29/GRSG/2014/15 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions, as part (see para. 17 above) of draft Supplement 3 to the 01 series of amendments to UN Regulation No. 43.
