I have been pondering your query.
Are you referring to a procedure for Pretensioned Bolts utilizing Turn of the nut method?
What the Auditor was trying to do was what the auditor is supposed to do.
See if your referenced individuals could do what you said they were going to do according to your procedure.
Possibly the Auditor saw an area of concern.
Not having your actual procedure I really couldn't speculate on the the Auditors requests or the point trying to make.
But the idea is to attain at least minimum required tension consistently not take the fastener assembly to the borderline of Fracture.
As Chris stated there is no Maximum tension but you only want to tension as much as required (anymore is a waste).
The only time the bolt is tensioned too much is when it snaps.
If utilizing the turn of the Nut you want to develop the proper snug tightness to just insure the minimum is achieved.
If this snug tight is higher than it needs it can lead to snapping fasteners when turns are made during tensioning.
Just My ΒΆΒΆ's
Hope it Helps more than hurts
Just got our Certificate this week for another year of the Building standard qualification audit we went through.
Don't you Love them
But Good Luck and if you want to post or PM the procedure I maybe could answer more.
