What is the purpose of an ABE (General Operating Permit) for window tinting behind the B-pillar?

Hello everyone,

To achieve thermal insulation and UV protection, I would like to subtly tint the windows of my car behind the B-pillar.
Actually, from the B-pillar onwards, almost anything is allowed.
Here, you're allowed to stick a Bart Simpson figure to the window with a suction cup, and you're allowed to put an advertisement for a nail salon on the rear window, but if you put even a slightly tinted film on the window, you suddenly need an approval certificate (ABE).

However, I don't want this ABE number on every single sheet. With Foliatec, the ABE number is printed as a sticker on the film, which makes it difficult to use the squeegee properly. They could actually include all the parts, so that you can assemble it yourself later.
I also find the embossed numbers to be a disadvantage. I would like to choose the cut in a way that the number is not visible.

Does anyone even care if I install a tinted film behind the B-pillar without any visible markings? It doesn't seem logical to complain about a film being installed behind the B-pillar. Assuming it's not blinking...

Yes!


To explain your initial question...

The chipping behavior of the parts that are completely covered with film changes. Therefore, the protection of the occupants will fundamentally change as well.
In the ABG (ABE no longer exists ), it is described that the fragmentation behavior does not worsen. To now obtain a mapping from slide to ABG, the approval number must be clearly visible on each slide.


EDIT: In my Skoda, I have the 3M film on the side windows (the rear window is clear for various reasons), and the license plate is hardly noticeable.

The 3M films in my 206 have a large grid pattern printed diagonally on the film. It doesn't interfere with the installation, but it looks quite strange from the inside. It is not visible from the outside, even when looking through it towards a non-tinted pane of glass.
