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.

Next we see that it is a felony under Federal law to violate the integrity of a certification by any party.

Up next we see that the mill has certified that the material has not been contaminated by elements that can lead to embrittlement…..with the caveat “while in their possession”.

Here we see a reminder that the tests reported were specific samples and additional testing may produce a different result within specification limits
Electric furnace melted and billet cast with a 16.5 to 1 reduction from cast size to bar.

Just a reminder that the content of any certification depends on the various material specifications and standards involved and never ever forget to – CHECK THE SPECS!!!!!!
