I had no idea where to ask this question so I stuck it here.
We make a few parts which, on the part print, have a "General Note" covering unspecified linear tolerance as follows:
Basic tolerance up to 25.4 mm = +/-0.25.
Additional tolerance for each 25.4 over = +/-0.025
We have always taken that as meaning the additional 0.025 gets added at 25.5 mm, 50.9 mm, etc. I am now "arguing" with one of my NONAUTOMOTIVE customers who says the additional 0.025 doesn't get "added" until 50.8, 76.2, etc.
I'd sure like to hear what some of you feel (or know) is the "correct" interpretation.
Thank you in advance,
Bill
