SVA compatibility of a windscreen?
ghetto_eddie - 30/4/08 at 12:18 PM

Hi all,

I am going to be using a Jaguar XJS windscreen, albeit modified in size in my scratchbuild.

I plan to modify it in the same way as THIS thread.

However i dont want to run into any issues with the SVA test, so i took a snap of the markings on my screen.

Does anyone know if the markings shown in the picture will be ok for the SVA?

Regards

looks fine, the MOT guy also looks for the mark. Assuming that it's not in removed when you cut the glass then no issues.

From my initial measurements it looks like it will come close to the markings, but not totally cut them off.

If this is the case the inspector would (assumably) have to lift up the edge of the windscreen rubber to see the full stamp. Would this be ok do you feel?

Sorry for the anal as hell questions... but i am going to do my damnest in my build not to give the SVA guy a reason to fail me on the bodywork!

so long as he can see the full marking, even if he has to lift the rubber sounds fine

Can't see the actual BS number in your photo, but it looks fine to me otherwise. Note it only says it must bear the marking, not that it has to be visible. If you have evidence of the mark even if it's behind the rubber you should be able to argue the point even if its a bit awkward.

Y'know, I was pondering the other day... It really wouldn't be at all difficult to reproduce that mark and apply to any windscreen you felt like...

The parts that show that glass to be of the correct standard are.

The "kite" mark
The FW (front Windscreen)
The HP (High penetration) which shows it has the higher graded interlayer that HAS to be used on front facing glass in vehicles
The DOT codes shows it was manufactured at an approved factory.

I think you will find that the marking has to be within the "sandwich" and not etched on the face of the glass.

The rule says it needs to be applied by the manufacturer (it used to be possible to get the supplier to put one on, but no more).

Personally I think forging the mark (which seems to be what you are suggesting but in harsher words), would cause really painful problems at SVA if they picked it up.
