IATF 16949 Cl. 8.7.1.4 Control of reworked product

[icybluen66]

Hello everyone,

My name is Karen and I'm a SQE working in fastener industry.

I just conducted a process audit at a heat treatment company and I had argument about IATF 16949 clause 8.7.1.4 with him during the audit.
I caught him reworked 10.9 and 12.9 bolts without customer approval.
But the manager from this heat treatment company claimed that clause 8.7.1.4 doesn't apply to special process like heat treatment.

Per my understanding for clause 8.7.1.4, any rework shall have risk analysis (PFMEA) and shall notify customer prior.
The supplier shall not take any further action before receive customer approval.
If customer approved for rework, the control plan shall be revised based on PFMEA.
All re-inspection records and relative documents shall be obtained and traceable.

Could any expert here help to let me know if I understand the clause correctly or not?
In addition, could any expert here know if there's a standard for the rework for 10.9 and 12.9 high tensile parts?

Thank you!

Hello everyone,

Hi Karen, and welcome to the forums.

I just conducted a process audit at a heat treatment company and I had argument about IATF 16949 clause 8.7.1.4 with him during the audit.
I caught him reworked 10.9 and 12.9 bolts without customer approval.
But the manager from this heat treatment company claimed that clause 8.7.1.4 doesn't apply to special process like heat treatment.

Is the heat treat supplier certified to IATF 16949, or have you flowed down the requirements of IATF 16949 to them? If so, 8.7.1.4 applies to all processes where rework can be done. If not, what requirements have you specified?

Per my understanding for clause 8.7.1.4, any rework shall have risk analysis (PFMEA) and shall notify customer prior.
The supplier shall not take any further action before receive customer approval.

The standard says "If required by the customer, the organization shall obtain approval from the customer prior to commencing rework of the product." Did you require them to get your approval before doing rework? What does your legally binding PO/supplier agreement say? If it doesn't mention this, then your approval is not required. PFMEA is not specifically required, but is listed as an example of risk analysis. Some method of risk analysis is required (again if they are certified or you've flowed the 16949 requirements to them).

If customer approved for rework, the control plan shall be revised based on PFMEA.

If the PFMEA is updated the control plan should match.

All re-inspection records and relative documents shall be obtained and traceable.

A "documented process for rework confirmation" is required. Traceable records are required.

In addition, could any expert here know if there's a standard for the rework for 10.9 and 12.9 high tensile parts?

Sorry I can't help with this one.

I would also see if/how Cqi - 9 for heat treating applies.
