Question in regards to validation of test reports.
To give some background information we perform verification of all incoming material. We perform visual inspection and compare it to received documentation to ensure the material and paperwork match. additionally, we compare the certificate of analysis to the standard the alloy must comply with.
Some of our customers have identified raw material to be a critical item (Al 304)
my question is about sending the raw material to a third party for validation.
when the original supplier performs the testing on the raw material, the testing is against Al304.0 (which is ingot form). According to ASTM when pulling a sample for spectrochemical analysis you melt the alloy down and use a mold to form the sample. but in doing so this changes the composition of the metal. therefore, when we send the sample out it must be tested against 304.1 (die cast form). would testing against this form comply with AS9100 requirements? technically we are testing the metal just to a different form.
