In addition to strict production processes, AGC ARG performs a large number of quality tests and starts mass production only after a final fitting test on a real car. Every AGC replacement glazing is homologated according to the latest official revisions of the UN R43 Regulation, the European 92/22 Directive and the American standard ANSI Z.26.1.

In quality terms , AGC ARG glazing can be considered as Original Spare Parts or equivalent.
