I can't give you itemized values for each defect category because we don't ask operators to distinguish between them, and we haven't done any serious research to do so either. I do wonder this, though. I read data somewhere from 14 years ago statin

I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec di
