ISO8788:2000 was applied whereas the latest issue is dated 2020. However, as previously said, this last revision of ISO8788 is an editorial revision, so there is no impact on the parts and on the qualification.
Axial load test at 80%: QTR gives the description of test bolt, which is GALAS00795, made out of low-alloyed steel, 1100 MPa UTS, cadmium plated. However, according to the corresponding photograph after testing, this bolt seems to be made out of stainless steel or Inconel 718, with or without passivation (difficult to know).
Could you please clarify?
Same question for axial load test at 100%.
Torque out test: in QTR, applied torque is 10,4 N.m. This anchor nut is made out of steel, so, torque value should have been 13 N.m instead of 10,4 N.m (see ISO5858, table 7, left column).
Many thanks in advance,
Best regards.

QTR was updated . Evolution of ISO8788 is editorial so no impact on the parts

Tests were performed with Inconel 718 test bolts ( see QTR updated) , it was a mistake.
Same question for axial load test at 100%. Same answer as above
Torque out test: in QTR, applied torque is 10,4 N.m. This anchor nut is made out of steel, so, torque value should have been 13 N.m instead of 10,4 N.m (see ISO5858, table 7, left column).
It was a mistake. The test was performed with 13Nm value and pass without any issue. See QTR enclosed.
Good receipt,
