Performance Test Results - for TESTS or for REQUIREMENTS specifiied in Design Record?

[Corey Jordison]

Situation:
- design record of purchased part contains 18 functional requirements (temperature resistance, etc.)
- design record says that 12 of them shall be tested annually
- supplier is providing me a PPAP with Performance test results for 12 requirements
I am rejecting the PPAP and saying to supplier: hey, there are 6 requirements missing.
Supplier's response: hey, we don't have to test the other 6, because the design record is saying that we have to test only 12 requirements out of 18

I am preparing my response: hey Supplier, you are wrong, see PPAP manual clause number... and then I open the PPAP manual in order to check for clause number and see in clause 2.2.10 that supplier shall have performance tests results for tests specified in design record. For tests, not for requirements specified in design record. Does it mean that my supplier is right and they only have to submit 12 test results?

On the other hand: they have test methods described in design record for 15 requirements out of 18, which makes it even more crazy...

So how many test results they must submit to me:
- 18, because this is the full list of requirements from design record
- 15, because test method is described only for 15 of them
- 12, because design record is saying that they shall test only 12 of them

Thank you very much in advance for your replies because I'm lost here...

hi,

1. In principle, supplier need to submit for all 18 requirements.
2. As per design record supplier to test for 12 requirements annually once.
3. Remaining 6 requirements supplier has to have a frequency to perfrom testing / or you need to provide him the frequency based on the criticality

If go through PPAP 4th edition Foreword & Purpose we can find

"....all customer engineering design record and specification requirements are properly understood by the supplier and that the process has the potential to produce product consistently meeting these requirements during an actual production run at the quoted production rate"

2.2.10.2, on page 7 of the 4th edition PPAP manual:

The organization shall perform tests for all part(s) or product material(s) when performance or functional requirements are specified in the design record or Control Plan.

It seems to me that if there are 18 functional requirements expressed in the design record, the supplier must provide data in the PPAP submission for all 18, but only 12 of them must be retested annually.
