22. The expert from Germany introduced GRSG-105-24 proposing an amendment to UN Regulation No. 43 to cope the difficulties of technical services located at high altitudes to fulfil the barometric pressure conditions required for the impact test. GRSG noted some comments and agreed to resume consideration of this subject at its next session. For this purpose, the secretariat was invited to distribute GRSG-105-24 with an official symbol.

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.”
