Is it possible to update NADCAP certificates for MTL and CP?
Salt spray test: could you please add some pictures of tested nuts after 336h exposure?
Tensile tests at 80% and 100% loads: as per ISO5858, clause 5.6.1 and as per QTP, sections 5.6.1.1 and 5.6.1.2, 8 parts shall be tested for each tests.
However, in QTR, we have 4 parts tested for each test.
Could you please clarify?
QTP, QTR and PFC are dated November 2020. However, qualification batch was manufactured in 2016 or 2017. Indeed, in PFC, surface treatment operations were carried out at HFS St Cosme facilities. At that time, surface treatment workshop was operational, but now, it is not.
So, for future batches, we should have MCRs. Is it planned?
Many thanks in advance,
Best regards.
Another comment:
In QTR, roughness measurements on nuts are ranging from 0,077 µm to 0,141 µm.
This very low. Are we sure of that?
Many thanks again.
Regards.
Hi Julien , below my answers in blue
Salt spray test: could you please add some pictures of tested nuts after 336h exposure? the parts are in conformity I saw them directly on site, on the photos it is not easy to see

Could you please clarify? it takes 3 tries and there is a test until breaking for info

Is it possible to update NADCAP certificates for MTL and CP? ==> Yes MTL certificate has been uploaded on Additional documents – due to the fact we have no surface treatement department and we use surface treatment subcontractor we do not have a CP Certificate from Nadcap.
Salt spray test: could you please add some pictures of tested nuts after 336h exposure? ==> Done see QTR 8690E updated page 14.
Tensile tests at 80% and 100% loads: as per ISO5858, clause 5.6.1 and as per QTP, sections 5.6.1.1 and 5.6.1.2, 8 parts shall be tested for each tests.
However, in QTR, we have 4 parts tested for each test.
Could you please clarify ? ==> ISO5858 standard is not clear, it can be interpretated. QTR8690E updated see page 24 and 26.
