Rework vs Repair

Repair vs Rework 

A general rule applied by many in automotive is:

Rework puts the part into the same condition that a first run good part would be.

Repair puts the part into functional suitable condition, but it is apparent that some additional work was done.

Rework Definition :

Correcting of defective, failed, or non-conforming item, during or after inspection. Rework includes all follow-on efforts such as disassembly, repair, replacement, reassembly, etc 

or Is to change an item in order to improve it or make it more suitable for a particular purpose, e.g. to rework a defective product into one that exhibits the quality required for acceptance.

Fix the part to meet specification.

Repair definition:

The act of restoring the functional capability of a defective article in a manner that precludes compliance of the article with applicable drawings or specifications. Repairs are generally changes to an unacceptable end product to make it acceptable in accordance with original functional requirements.

Fix the part so it is usable, but does not meet specification.

From the ISO 9000:2000 edition



* 3.6.7 * rework – action on a nonconforming product (3.4.2) to make it conform to the requirements (3.1.2) 

NOTE Unlike rework, repair (3.6.9) can affect or change parts of the nonconforming product.

* 3.6.8 * regrade – alteration of the grade (3.1.3) of a nonconforming product (3.4.2) in order to make it conform to requirements (3.1.2) differing from the initial ones

* 3.6.9 * repair – action on a nonconforming product (3.4.2) to make it acceptable for the intended use 

NOTE 1 Repair includes remedial action taken on a previously conforming product to restore it for use, for example as part of maintenance. 

NOTE 2 Unlike rework (3.6.7), repair can affect or change parts of the nonconforming product.
