Hi guys I've had a brief chat with an ex colleague and he has had a disagreement with one of his new colleagues about holes on chassis. He has said that whenever there is a hole in a chassis that is within 30cms of a mounting point he fails it. Not only that but that he also classes body welds on a monocoque chassis as mounting points so that warrants a rfr if within prescribed limits. Right or wrong.? Thanks guys. Love the fact us testers get into disagreements such as this

As a worker in a responsible skilled roll within a skilled trade why am I paid so poor??

bit confused,are you talking about premade chassis holes or corroded ones?body mounts only apply to separate bodies and have to be pretty bad to fail anyway,cant recall the last time I saw welds rotted bad enuff to fail,holes yeah,loads.

Most car's don't have any body mountings, only such as Land Rovers ect that have a clearly defined chassis have any body mountings. If you are talking about the reinforced parts of a car underside being corroded enough to have hole's then mostly the prescribed area rule covers that & a failure is only justified if it is within 30cm of seatbelt, brake, steering or suspension mounting points.
One of the many things that wind me up is failures on body mountings that aren't there!

Autodata helped in this grey area back in the 90's

all we got now are a couple of images in Appendix C – Structural Integrity and Corrosion
Rfr 6.1.B.2 excessive corrosion of a load bearing body or chassis member which seriously affects its strength within 30cm of the body mountings...doesn't distinguish between monocoque or ladder chassis

6.1 Method of Inspection B - States -

Body Security (applies to vehicles with separate bodies only)

I reckon that's clear enough, and certainly rules out monocoques

If I was to agree with you, that would make us both wrong !
