Drawing requires material to be EN2399, EN3638 or EN3639 for the nut and EN3638 or steel FE-PA15 for the washer

The material certs within this renewal do not state these materials. what is the link between the material used and the material stated on the drawing.

  For the washer the required raw material is FE-PA92HT per EN 3638 . For this raw material , the standard TR3791 gives equivalence between FE-PA92HT and A286 per AMS5525 ( See document TR3791 highlighted page 8 table 2 enclosed) . So the CoC of the supplier of the washer raw material – AT 1448830 – ( see AT1448830 raw material CoC highlighted enclosed ) certified that the raw material is compliant with AMS5525. Our internal supplier specification SAM0049 make also the link with AMS5525 ( See SAM0049 highlighted)
