IATF Definitions - Reworked product (8.7.1.4) vs Repaired product (8.7.1.5)

[Peters]

I don't know why there are 2 similar but separate clauses for rework and repair. What is the difference between rework and repair?

Definitions in ISO 9001:2005:

Rework - action on a nonconforming product to make it conform to the requirements.

Repair - action on a nonconforming product to make it acceptable for the intended use.

Well... it's not so clear...

I found such definitions:
LINK

Rework – Bringing a non-conforming part back into conformance by simply reprocessing a prior sequence.

Repair – Bringing a non-conforming part back into conformance using methods outside the original process.

And such definitions:
LINK

Rework – The act of reprocessing non-complying product, through the use of original or alternate equivalent processing, in a manner that assures compliance of the product with applicable drawings or specifications.

Repair – Action on a nonconforming product to make it conform to requirements. Unlike rework, repair can affect or change parts of the nonconforming product.

But the most important question - what is the IATF idea? And why it's 2 separate (but similar) clauses?

Hi,

I guess rework is related to parts before it reaches the end users e.g. to correct nonconformity during manufacturing in the supplier chains.

And repair is related to parts after being used by the end users.

I remember I read something in TS or rules that states about field service agreement where suppliers are to repair products in the field after having been used and broken etc.... So I am just aware TS wants to control these post delivery activities too but never seen a site with such service agreement so far.

Rework makes a nonconforming product, conforming.
Repair makes a nonconforming product acceptable for use.

There are some examples of repair & rework.

You make a cup of soup, and if it is not salty as the specification; you can rework by add more salt, and if it is too salty you can add more water to make less salty but the soup becomes diffirent to the original specification.

To add a cross industry aspect:

Rework

Rework - Definition

Repair

Repair - Definition

The definitions in ISO 9000 are the ones that apply to IATF 16949, so any other definitions you find on the Internet are only going to muddy the waters.

From the ISO definitions posted, you could summarize them to say this:

Rework brings the product into full conformity with all original specifications.

Repair makes the product functional, but it does not meet all original specifications.

A note that I *think* is correct: When referring to "repair" in this discussion we are referring to "repair" of product prior to shipment, as opposed to a product which is returned as defective or is out of warranty and returned to be "repaired".

Please correct me if I am wrong.

Formally you are right, but when I read IATF 16949 it seems to me that IATF has a little "creative" approach to ISO terminology...

Sorry, did you mean "rework" here?

No. For example, in this discussion "Repair makes a nonconforming product acceptable for use" is stated.

Just making clear the scope of the definition in this discussion.

For example, I had a 1996 Pontiac Bonneville SSEi some years ago. Part of the instrument cluster went out. The dealer did not do replacements. I couldn't get them to sell me a new or refurbished cluster. There was the option of getting one from a junk yard, but the dealer wouldn't touch that option because of some law that they had to keep the cluster serial number in the car (or something to that effect). The bottom line was the cluster kept the car's milage in it. The cluster had to be removed and sent to GM who "repaired" the cluster and returned it to the dealer (same cluster with the serial number linked to that specific car). It wasn't nonconforming product - It was out of warranty part which had to be returned for "repair". Much like an FAA repair facility repairs parts which have broken but can be fixed/repaired. Traceability and all of that stuff.

I *assume* we are not talking about "repair" in that sense.
