Well of course insurance company cannot give approval for isofix anchors fitted to car that does not have them from factory.
They don't even give approval for seat belt installation for old car where they are not fitted from factory (or, they cannot stop you putting them but insurance may not be valid for those).
We can end this discussion to conclusion that if you do not have made certified tests for any installation or repair you have made to your car AND also have approval for that from your insurance company, you should not do it. I see no point going through these bizarre arguments that have nothing to do with real world.

Ok, so if you don't understand it, then I wont either.
This is pretty much like changing brake pads or doing other safety related maintenance to your car. If you are not expert (I mean like educated car mechanic specialist), then you should not do it. Or would you do it anyway? I bet you are not calling your insurer to be sure can you change your brake pads or wheels by yourself, what if brakes fail or wheel drop of at high speeds..
Common sense is usually what it takes, it is same here. Little engineering skills will also help.
When you install that isofix anchor in, you can inspect that installation and think it through and then decide is it safe for use or not. That is what I did here and I decided that it is safe for use.
So I'm very much in my senses from the beginning.
I'm happy to receive advises and tips, but I don't need any guesses with no or very little knowledge behind them (like why I should do dynamic load test instead of static load test, as I know the result is the same and also I know how it is tested by authorities = by static test). I understand it is sometimes hard to get all the info and facts out from the pictures provided, maybe this might be also a problem here.
No offence.

Im still very satisfied with my test and also with my isofix installation. As I have mentioned.
Do you think anyone, with or without isofix, would have survived in that Omega crashing 200 kmh basicly to wall?
Do you already understand is there difference between static load and dynamic load test with the same maximum loads (static and peak load are same)?
Have you inspected how that isofix anchor is fixed to sheet metal and also between back seat and sheet metal and noticed how well it is fixed?
This is pointless discussion if you dont understand the basics in this matter.
Sure I can make another test by pulling that anchor installed in car with load of 800 kg as it is tested (static load test), but then I need spare car for that. Anyone want to donate one?
And I do know they are my kids, dont need to mention it on every post

I did not ask insurers, I dont know why should I. Would it prevent any crashes?
It is enough that those will hold far more than they normally be tested. And they are safer than only with belt hold seats for 0-2yrs.

This was not testing floor pan, only does bending the loops cause any harm. It does not.
Also back seats act also as attachment, they are press fitted over anchors so they would not move forward even if I take the bolts out.
What is the difference between dynamic test where peak value would be 2000 kg's mass vs static test with mass of 2000 kg's?
Btw, here is your original worry. Nothing to do with floor pan
"Agreed with the principle of the idea, but question the integrity of the attachment points following bending in a vice..."

Ok, I did some testing. Bolted brand new isofix anchor to IPE-beam, attached 1000 kg's to one unmodified loop and to modified=bent loop (one at a time as my "test rig" cannot lift 2000 kg's ).
Result: no matter is the loop bent or not, it will not brake and it seems that they behave similar to each other. So it will handle at least 2000 kg/33 kg = 60,6 G-forces and I still believe it is safe to attach my childrens to it.
Here are some pics also:
Assembly to IPE-beam
Bent loop at front and unmodified at back
Test rig
1000 kg's mass
Control lift with unmodified loop
And it is up
Unmodified loop after lift
Now with bent loop
And it is up also
Bent loop after lift
This is the only situation I want to see isofix anchor looking like this..
Same from side
Unmodified loop
Unmodified loop
Bent loop (that paint is peeling off, not metal cracking)
Bent loop (same here, only paint peeling off)
Edit. Resized some pics.
I did not have time to scrape those paints off, I might do that later to check is there any hidden cracks under the paint.

Omega General Help / Re: Where to Locate Axle Stands (Rear)
« on: 09 May 2019, 07:54:06 »OK, thanks correction, no problem yet, have to remove it first. Is there any typical life time for rear bearing of Omega?
I don't know is it typical, but my originals lasted about 200 000 km and 220 000 km (or at least I could not find any markings that they have been replaced earlier).
Then one re-newed needed to be replaced after 100 000 km. Now I'm waiting was it just bad batch or is the other one also going soon..

« on: 30 April 2019, 08:20:13 »Can't that complicated to make your own bracket that fits perfectly to the car?I suspect this, and that they're subjected to much more than a single static load test
Or do they have to be approved by some authority?
Actually they not only make one, but they do two static load tests (with less load I'm intended to do):
Quote
6.6. Static test requirements.https://www.unece.org/fileadmin/DAM/trans/doc/2016/wp29grsp/GRSP-60-05e.pdf
(...)
6.6.4.2. Forces shall be applied to the static force application device (SFAD) in
forward and oblique directions according to Table 1.
Table 1
Directions of test forces
Forward 0° +- 5°
8 kN +- 0.25 kN
Oblique 75° +- 5° (to both sides of straight forward, or if
any worst case side, or if both side are symmetric,
only one side)
5 kN +- 0.25 kN
Ok, I don't have that fancy static force application device (SFAD), but I'm sure my "test rig" will be good enough

I think that is the safest way to buy premade, price is so low and it is just bolt-on basicly.

« on: 29 April 2019, 06:54:14 »If I can get enough mass gathered, I'll try to get it break. Also it was on my mind to bent other loop even more after first test.
That static 1000 kg load is the dymanic shock load that peaks when 33 kg mass decelerates at 60 g's. . Based on constuction of isofix, all other directions where connection can move are "flexible"/jointed/hinged so most pulling force is caused to loops on frontal impact on car.
Sorry, meant to say "That static 1000 kg load on one loop is the dymanic shock load that peaks when 33 kg mass decelerates at 60 g's." So if one loop does not break when hanging 1000 kg on it, two loops can hold 2000 kg without breaking. But we will see.
