NCT & Window Tinting failure

i'd say your timt was added by previous user.
Original tinted glass, are Tinted Glass, not a tinted film.

The film will peal straight off, but will leave a messy sticky residue.

search youtube for detailed guides on how to remove it, its best to see the process in action

Not up to date on this new rule is this an automatic fail or do they test the opacity of the tint surely there has to be a legal limit

Thats in the Uk where the cops carry opaque meters is that the case with the NCT do they actually measure the transparency or just fail if you have tinting fitted!

OK

A friend of mine was only last week not allowed to do his driving test due to having tinting fitted but they did not measure it , just told he had failed as the tester refused to get into the car and this tint is well within the leagal limit as it is very light !

just to let people know, any tint, and i mean any form of tint now fails the NCT if on the drivers or front passenger window.

even the lightist tine available to the tinting companies fails the NCT. the most up to date one is clear to the nakid eye and clear when put on and is only put on to avail of the UV protection as such.

Completely False. It must allow 65% light through. I know of 2 cars that have passed the NCT in recent days with tinted front windows.

Incidently, the Construction, Equipment and Use of Vehicles act 1963 states that you cannot have anythin on your windows that "obscures" your view of the road, so technically you should not have any tint on your front three windows.

Also under the EU regulations brought in by the Car Entry into Service (Amendment) Regulations 2008 it states that your tint must allow 70% light through the front three windows.

Its funny because the NCT has also put a 99dB limit on car exhaust noise and the above act limits it to 74dB.

So the law and the NCT are at odds with each other.

I'm not entirely sure on the exact figures, but even clear glass without any tint has a light transmission of only 92 - 95% or thereabouts.

Clear glass without any factory tint is pretty much extinct on modern cars and most of them have a tint already, reducing light transmission to around 75 % for the lightest tint.

So once you put extra tinting film on top of that you're automatically below the limit even if your tint film label says it's only a 15% tint ...simply because you never start from 100% in the first place.

Which is exactly what I said in my original post. All tint other than the clear tint will fail it. please read my full post and don't quote sections of it.

Your first post #10 claims that any tint will fail the NCT (incorrect) and that the available after-market tints fail (correct). Nowhere does it mention that clear tints will pass. It was not until 2 other posters corrected you did you mention clear tint (which is still a tint btw therefore contradicting the 'any tint will fail' claim). You also claimed the NCT spec was 85% but I'll assume this was typo and I commend you on editing your post after you were corrected on this too.

I have read all your posts in their entirety, many times, so I'm very clear on what you have written. It's only in your subsequent posts that you say what you perhaps intended to say originally i.e. that light tints >=65% VLT are ok but dark aftermarket tints <65% VLT are not. On that we are in agreement.

My windows only let 30% light through and when my car went through the nct last tuesday there was no mention of window tinting on the list of fails, only emissions and lights

You were lucky. The new regs came into effect on the 1st April. Did you happen to notice if they measured the tint or not, perhaps they didn't have the equipment yet?

I watched the whole test and they never put anything on the window similar to the light tester things that ive seen in pictures and stuff. Rolled the windows down but that was it.

I'm not putting my through again because Im scrapping it but I wonder what would happen if I brought it for a retest now?

Well those amendments were made on 1st April so at a guess you'd fail

the 2 cars that passed, i find hard to believe that they are tinted tbh. the tinting companies such as Vision FX and Revolution Ireland even say that their lightist tinting does not pass the new NCT rule, only their clear film passes, which is a UV protection as stated in my original post.

people are so quick to jump in with "ha ha, your wrong" but take the tine to read the posts please

Believe what you will, but your providing false information. Tinted glass will pass the nct if it allows 65% light transmission, just because a few tint companies you know dont stock the tint doesnt mean they all dont.

Theres a couple of NCT testers on the site i run midnightclub and they will also confirm my previous statement.


OP, in the removal process, in all the cars ive had, its best to just rip the tint off in one quick motion, i find this leaves behind less adhesive. Tar and glue remover on a cloth will then remove the remainder.

That anti-UV tint thing is a bit suspect. No harmful UV light can pass through glass anyway.

Do any glass companies make glass that reacts to UV light, like glasses, where they react in the sunlight to darken and then go clear at night time?

This was an original feature of this Grand Scenic which is annoying that it can suddenly become an issue 6 years on. The tester was not having any of my plea that it was a car feature.

It couldn't have been ...international standards only allow for a light transmission > 70% on front side windows

Standard Requirements in terms of light transmission
ECE R43

WindscreenLT > 75%

Side windows forward of the B-pillar (in the driver's direct field of view)LT > 70%

Behind the B-pillar No value if a 2nd exterior mirror is mounted (otherwise LT must be 70%)

its easy enough to tell. Just roll your window down half way, look above and below the glass and you will see a difference between the 2

Even clear glass with no tint at all will show a difference as even clear glass does not have 100% light transmission but only 90% or so.

But most modern cars already have tinted glass on them (as in the tint is in the glass, not in a separate film. Usually the look slightly green-ish) and in that case they would have a light transmission of around 75%.

heat the window up with a black an decker paint stripper or a good hair dryer then it will peel straight off, Usually it will come off very easily.

Then just use washing up liquid and a blade to clear off the remaining glue.

This should work..did it myself

One of the plebs here.......All NCT centers got brand new window tint testers 2 weeks ago.......and yes, they are all calibrated, to answer your next question.

Hi. Same apply for factory tints? My 1991 8 has film tints from the factory and I'll be mighty upset if I have to modify it.
Cheers.

Cosmo K wrote: »

Are your front windows tinted as well? I always thought, factory tint was only available for the rear windows?

You might have a point there. Not sure. Previous owner could have matched them up. Build sheet doesn't stipulate which windows. I'll find out from learned owners. Ta.

Edit: in answer, yeah, they're also tinted.

maybe not a film, but some companies car windows come with a slight "tint" that is probably impregnated or sputtered onto the glass

Most cars these days come with factory tinted glass. This glass has a slight green tinge usually. The tint is in the glass, not on it.
Basically they throw a few spoonfuls of green goodness into the melting pot when they make the glass ...like your green or brown glass bottles, only slightly more controlled and somewhat less of it.
