Question  Frequency of spraying the test sample
Hello ,Everyone

GE Standard Practice Manual guideline denotes that based on acceptable statistical process control(SPC) system, the frequency of metallographic or other testing may be reduced.

Does this applicable to equipment /operator qualification / re-qualificatio or for the production quality control test samples?

How do you spray the test samples in daily production?

Regards!

RE: Frequency of spraying the test sample
Test samples are done with every single part processed with GE spm.
For other OEM's are not as strict and monthy samples are possible.
If you have a history of 100% success rate on test samples over a period of time. I would contact GE support and ask for their opinion on reduced testing frequency.
For critical parts I would follow the GE spm and do it with every part.
