Since EN4072-080013AE screw is too short to be fatigue tested, we should have a restricted qualification for length range from 006 to 019. However, maybe initial qualification was carried out with EN4072-080 screws with lengths long enough to be fatigue tested. Could you please check this?
Many thanks in advance
Best regards
Julien

  Hello Julien,
  Checking the original report, the reference chosen was also too short to perform fatigue tests. At the time of qualification, this did not imply any length restriction.
  For the renewal, I added on the ASD-Cert website a Certificate of Conformity for another batch of EN4072-080xxx OF 477687 (less recent) for which fatigue tests have been performed.
  I hope that this will allow the renewal for all the lengths.
  Thank you.
  Best regards

Hello Nicolas,

Thanks for adding EN4072-080xxx OF 477687 test report with fatigue test results.
I am happy with this answer, so, approved from my side (full length range qualification).
Have a nice day
Best regards
Julien
