We have been making aluminum Boeing parts for years. I took over as Quality Manager last year, and I keep running into finding problems that no one caught before. I just have some general questions on the specs and what is actually required. I see that for conductivity meters they state to calibrate every 6 months. We have an older autosigma meter. The new one is about $5500. I cant seem to find any other one on the market that is compliant that doesn't cost as much. We were looking into getting a second due to the fact of having to now calibrate every 6 months.
For our hardness tester. Is what I am reading correct? That you need to certify the tester every 4 months. We have been calibrating it annually with the verification check each day before use. How would one be certified to do hardness testing and could a company certify the hardness tester themselves?
