“ASD-CERT Technical Focal Point Application entry approval: Approved
extension of PQ 460 (EN 419-040-050-060-120) to diameter 080 and 100
throught MCR and dossier”
The “2” is missing in EN 419-040-050-060-120 (EN4129).
Same remark in “substantiation by analogy” section.
Not blocking, just something to point out.
EN4129-100: no double shear and no tensile test results on bolts available due to short length. Only tensile test on specimens were carried out.
EN4129-120 bolt reference is too short as well to perform both double shear and tensile tests on bolts.
Do we have a chance to get tensile and double shear test results for EN4129-100 or similar parts?
Raw materials: could you please clarify the link between “02-286CC-rev.N”, “SM-30-rev.C” and “SPEC-13MP-(RR)-revC” and EN2137, EN2442 or TR3775 called out by EN4129?

A: corrections done

A: AHG has made a overview of all past orders they have got. No manufacturing done in diameter 100 and 120 where the double shear test is possible.
there is no scheduled orders on these diameters where Double shear could be done as well . I have added a comment in order to mention this deviation for the 2 diameters.

A; the SM 30-rev C is a AHG document sent to Brown Europe in order to proceed the tests under the specification EN 2137 ( from TR 3775 )
Mant thanks Daniel and AHGs team.
All is clear for me now.
Approved from my side.
Best regards
