I'm looking for some advice on glass markings. I have found a company who do tempered glass (it's for side windows) to the correct spec. However they do it for horse boxes, buses etc and have no idea what BIVA is.
Are these markings acceptable? No issues if not, I've a way to go before I need glass.
Hmmm, photos aren't easy on here are they!

E11 43R-000595

That's all there is. Doesn't seem enough to me but what's missing that is required.

Have a read here:

By basic description, the glass you describe is fine for side/rear facing windows with that approval.

I mind seeing that E11 on car windows as a child
