IVA ans Windows...
Discussion
Right here's one for all you IVA buffs:
The manual seems to make out that ALL windows MUST be 'E' marked.
My problem is that in doing a roof chop, i will have the windscreen cut down, but the side and rear windows, i intend to make from perspex / polycarbonate, as its A:lightler and B: the only real choice.
or am i reading it wrong?

How I am reading the requirement:
The windscreen has to be glass and marked by the manufacturer. There is no mention of that screen having been subsequently modified. The E marking is still valid as it is a definition of the material/construction. If it is still in one piece and has no cracks then you would have to assume it was OK.
A side window either side of the driver has to be E marked by the material manufacturer. Not sure how you get round this one if using plastic unless you can buy plastic safety glazing in suitable sized pieces with the markings.
A side window behind the driver does not have to comply and is regarded as bodywork.
A rear window would have to comply but could be replaced with a blank panel as long as the car has OS & NS door mirrors.
Do be careful with the plastic as the stuff I used was clear to my mind but only just scraped through on the light transmission.

well i'll have a windscreen obviously...
caterams / westfields etc seem to manage...
7's get away with it because they have no windscreen surround or roof implying their intention to drive it completely open.caterams / westfields etc seem to manage...
If you have both surround and roof the tester is not fooled into think it will stay that way.

Not a bad idea, but there will be more than one examiner at any one test station, and as the others may be under lorries when you call, it may be difficult to get a clear answer.martin
Another approach would be for him to go with his best guess and see what happens at the actual test, there will almost certainly have to be a retest.

Rules rules rules, that means I have the same problem, I need to get my side windows moulded so how are the markings supposed to withstand the heat of the moulding process? We never had marked up side windows for racing!
What are they being made from? I was under the impression that glass ones get marked after they are formed.And how's that interesting car of yours coming along?
Hi Singlecoil,
The side screens and flaps are to be done from Perspex 4mm, they are a double compound curve so need to be moulded!
It`s coming on fine, rear deck moulds done, one door and one set of side window moulds done, hope to do the other door this w-end.

I have found a place that does e marked plexi / polycarbonate windows for the mini, so thats sort of solved. However ive decided for now, not to bother with the roof chop, and concentrate on getting the reat of the car done. can always do it as a last mod once the chassis is complete.

That is extremely impressive, I've just been through them twice with my jaw resting on my chest (figuratively speaking).Having slightly dabbled in that sort of thing I am well placed to see just how much work and talent went into that.
There's a mid-engined section on the busy www.locostbuilders.co.uk forum where I am sure you would get a good deal of interest. There's one chap in South Africa who is building a Lola replica, also from scratch, to a similar standard.
Have you thought of starting a thread here, maybe post a couple of pictures, 917 replica in the thread title should attract some interest!

Come on then. Don't keep it to yourself!the problem seams to be talking to people that the windows are manufactured by the car maker, then they have 3 samples tested, if this is ok, they kame the windows to size & shape and then they are screen printed with the correct e mark etc, so you can't just buy a sheet of e marked lexan / polycarb, or whatever they use

Could you not just buy a ready made, oversized, marked window and cut it down to the size required, making sure you do not cut off the marked bit?Gassing Station | Kit Cars | Top of Page | What's New | My Stuff
