What’s up guys?!?!?! This is Michael with Michael Talks Metal back for our 3rd and final round in our trilogy on aircraft quality alloy steel certifications.

If you have not seen the other parts check the links in the description for part 1 and part 2.

This last section of our sample certification contains various statements of compliance that supplement the other sections. The statements on this cert are meant to be examples and are specific to this mill, alloy, and specifications.

The first statement here is a confirmation that the results of tests have been reviewed and approved to the certified specifications we saw in the prior videos.

The second statement is indicates that the document is incomplete and therefore inaccurate if any copies are made excluding any data

The next line indicates that the standards for the testing methods were the revisions in effect at the time of production. Some mills would list specific revisions applicable.
