In QTR, 100% load test results seem to be missing. However, we do have both 80% and 100% load tests values in test report. Just something to point out, not blocking.
In QTR, clause 1.3.1, locking torque tests, 15 cycles. Why do we have synthetic oil lubrication? As per ISO7481, table 1, no additional lubrication is needed for locking torque test on this bolt/nut combination (nut: cadmium plated steel and dry film lubricant / bolt: cadmium plated steel).
In addition, for single cycle test, no lubrication has been done according to test report, which is in line with ISO7481.
Test report: hardness test results are shown in “Métallurgie” section, but not in “hardness section”. Apparently, there is a recurring glitch in a software. Not blocking.
Many thanks in advance
Best regards

Hi Mr. Gauther,
On behalf of Mrs. Lacombe, please find our answers :

OK Fine

It is a typo in the QTR 7504, we have updated ( see the QTR7504 A enclosed)
