I'm looking for guidance on a recognized, acceptable aerospace-industry approach to recording and evaluating measurement results. Let me explain. The drawing calls for a dimension of 0.050"+/-.005" and I'm measuring it to 4th decimal place (i.e. 0.xxxx"). If I have a result of 0.0552", how do I evaluate this result relative to the stated tolerance? Acceptable or not? And for reporting purposes, what value is reported, 0.055" or 0.0552"? And then the issue of rounding is to be considered? or not? Is there an aero industry standard that defines the proper, acceptable means of evaluation?
