Proposal concerning document GRSG/2015/22 to clarify the specification of the abrasion test machine.

The text of the German proposal (document GRSG/2016/21) in the tables in annexes 14 and 16 only refers to small windows as “windows into which a circle of diameter D < 150 mm is capable of being scribed”. OICA proposes to add the criterion of a maximum area limited to 200 cm² in order to align with the definition in paragraph 2.39 (“pane having an area of less than 200 cm² and within which it is not possible to inscribe a circle having a diameter of 150 mm”).

Proposal to replace the current Figure 2a with a more accurate drawing reflecting the meaning of paragraph 2.4.2.2 of the regulation. The new drawing addresses the lateral limits of any opaque obscuration of the window area.
