Can someone tell me where I can find, in writing, what the industry standard is for attribute gage tolerances. I have always used the following : When checking a 0.150" ±0.003" hole diameter, I would use a 0.153 minus pin for the Nogo and a 0.147" plus pin for the Go OR if I was checking a 0.150" ±0.003" shaft I would use a 0.153" minus ring for the Go and a 0.147" plus ring for the Nogo. I am having a "discussion" with Engineering and they said that I am incorrect because I would be failing good product. I tried to explain to them that we would want to error for the customer and if the gage did not fit the hole, then we would verify the dimension by using a measurement instrument such as a comparator or CMM. Without written published documentation, my 15 years experience is not worth much.
