hi
I cant find anyone who can cut and temper glass with E-marks on it. Most will cut and temper glass for auto use but it's etched with the british kitemark and a british standards number only.This was fine for sva. I've been told E-markings are for mass produce glass such as windscreens and also only those windscreen manufactured in the EU carry the E marking anyway.
If it applies to plastic as well then all dino builders are in the same boat. Unable to get passed Iva. help
