Our current procedure (for any calibration - in house or outsourced) requires checking all test points before even cleaning the gage.
I question whether this is overkill in our procedure.
Is this really what the standard is implying?
I personally would think that it is implying "before readings" are to represent readings collected before any adjustments are made (not including removal of build up during shift production)??
When we have only a 5 micron tolerance on plug gages, this could make several plugs appear out of tolerance (after only one use)... but when they are wiped off they are fine.
This shift build up, does not affect product quality because it simply slides up the gage when it is inserted into the next part and is wiped off each shift.
Wondering what others consider a "before" reading to be.
If there are any TS auditors out there, please give insight.
Thanks!

slightly, I guess, but I once took a job as A quality manager and found that the incoming inspection department had an 80-inch vernier caliper. Naturally, I was curious as to what it was used for. Turned out that it was used to measure sheet metal panels that were about five feet long, toleranced at +/- .010." I queried the responsible engineer who said the close tolerance wasn't really necessary; he just defaulted to the block tolerance for 3-decimal place callouts. The tolerance got changed to +/- 1/16" (which was still liberal) and so far as I know, the giant caliper was never used again.
