  1. Same remarks as for qualification 1372-1.
    Many thanks in advance

    1. In QTS, why EN2786 (silver plating) is mentioned? EN2906 has no finish which would mean only passivation process as it is actually the case. Thus, we should have EN2516 or AMS2700 (or another passivation process standard provided it belongs to aerospace domain since there is no requirement about passivation in EN2906).

      ==> Please see the QTP updated . EN2786 was cancelled and replaced by EN2516 , so thickness and adhesion are no applicable .

      In test report, “Dureté / hardness” section: HV5 9999 is written. This is just, to me, a typo and hopefully, hardness test results (HRC units) are listed in “Metallurgie” section. Thus, this is not blocking, just something to point out.

      ==> Take into account

  2. Dear all,
    Thanks for replying.
    EN2786 is still mentioned in QTP revision 2, clause 1.1.
    However, this is just a minor residual typo.
    Thus, approved from my side.
    Best regards
    Julien
