Seek advice from someone that passed through NADCAP AC7102 and AC7101/3

[Sorin]

OK...so we get HT audited - NADCAP.

Among the checklist we have (o/c) AC7102 and AC7101/3 - mechanical testing.

And there is one interpretation where I do not agree with the auditor....

In AC7101/3, para 15.1 reads

15.1 Code "Y" - Round Robin Required
The laboratory shall demonstrate participation in an acceptable
Round Robin program.
[ ] Approved
[ ] Currently in progress
_______________________

Code Y refers to the third page in AC7101/3 which lists the types of mechanical testing and where Y is

Y Low Cycle Fatigue [ ] ASTM E606

Now...we are not doing this type of testing. The only testing that we do (from AC7101/3) is
A Room Temperature Tensile [ ] ASTM E8

_______________________________

My interpretation is that the RR is required for Low Cycle Fatigue ONLY.
The Staff Engineer is saying that we must do a Round Robin program for tensile too.

Anyone that passed through this - can you offer insight?

Note: We are not a laboratory per se nor do we seek certification against AC7101 (which is for laboratories) - we are a foundry and we do our own tensile tests ONLY - nothing from outside.

Thank you in advance......

Let's move this question and double the exposure.

Any takers?

Something does not look right. The finding states that it against AC7102 rev A but the current revision of AC7102 is rev E and there is no section 6.13
Have you called the staff engineer and talked to him?
Everyone has a bad day now and then Just aproach him from a point of confusion and clarification to find out exactly why the finding was issued.

I think it was a typo and instead it was AC7101 rev A (and not AC7102).

Let's consider it was a typo....being that I was audited against AC7101/3 only and not against AC7101, can I have a finding that is related to AC7101?

Form the latest HT audit handbook
E1.1 Room Temperature Tensile Testing
• Round Robin testing is required when the Supplier performs RTT per AC7101/3 Table 1.
(Guidelines to follow when available.)
No I am not aware of any guidlines issue yet. Give Marcel a call but the guidance looks pretty clear since you perform tensile testing to E8 as indicated on your audit.

This is what I was looking for....

If you have any other questions send me a PM. I work in a foundry with NADCAP HT and might be able to share some tips
