Proposal to amend para. 2.5.2. to change the lower vertical datum point from 5 above the horizontal to 4 above the horizontal, and amend Figure 3 to reflect this adjustment. The modification harmonizes the location of the lower datum point with the angle of obstruction requirement and resolves an inconsistency in UN Regulation No. 43.

Proposal to amend para. 8.2.1.1. to replace “Optional distortion” with “Optical distortion” in the table of tests for windscreens and glass panes. The amendment corrects the title of the optical distortion test listed in the table.
