  1. Conditions to renew qualification (ACP-003) of EN3038-040 bolts under ISO8168 technical specification (initial qualification by analogy with EN3038-050 qualification 938):
    • Photos of Micrographic cuts are missing. Please provide ASD-CERT with them.
    • Photo of the marking is missing. Please provide ASD-CERT with it.
    • Parameters for the surface treatment are missing. Please provide ASD-CERT with them.
    • Information about heat or cold treatment is missing. Please provide ASD-CERT with it.
    • Please also provide ASD-CERT with the corresponding EN9100 and ISO17025 valid certificates for both laboratory test sub-contractors (Westmoreland and Dickinson).
    • The report mentions that short bolts are not qualified and the double shear test was not done. The PQ certificate shall mention this limitation to 8 millimeter bolts in order to advice OEM purchasers.

    1. You will find enclosed photo of micrographic cuts.
      You will find enclosed photo of the marking.
      Surface treatment is passivation performed in accordance with EN2516.
      Parts are produced by cold forming.
      You will find enclosed NADCAP and ISO1725 for both labs Dickson and Westmoreland.

      In our case for the reference EN3038-040006A, the nominal value of the diameter is less than 4 mm, double shear is not required whatever the length of the bolt. I’m assuming the qualification will be valid for all bolt lengths for -040. Could you confirm that to me please?
