Major Nonconformity vs. Minor Nonconformity - Definition and Differences

[hibou]

Does someone know where the definition of 'minor' and 'major' non conformity/conformance can be found ?? It is critical to know where the treshold is...

Tx.

Also you could get a copy of the AS9104 Standard (Registration/Certification Aerospace Requirements-Buy it) that defines the classifications, I believe.

Often times there is no definite 'threshold'. There are gray areas.

I just did a quick search, just to make sure, but neither ISO 17021 nor ISO 19011 provide definitions of "Minor" and "Major" nonconformities.

See my edit. It actually defines it in AS9104. Sorry you must have been posting at the time of my edit.

Here is the definition from AS9104:

The automotive TS Rules 3rd Edition defines them as:

Major nonconformity
Is one or more of the following:
• The absence or total breakdown of a system to meet an ISO/TS 16949:2002 requirement. A number of minor nonconformities against one requirement can represent a total breakdown of the system and thus be considered a major nonconformity.
• Any noncompliance that would result in the probable shipment of nonconforming product. A condition that may result in the failure or materially reduce the usability of the products or services for their intended purpose.
• A noncompliance that judgement and experience indicate is likely either to result in the failure of the quality management system or to materially reduce its ability to ensure control of processes and products.

Minor nonconformity
Is a failure to comply with ISO/TS 16949:2002 which based on judgment and experience is not likely to result in the failure of the quality management system or reduce its ability to ensure controlled processes or products. It may be one of the following:
• A failure in some part of the client's quality management system relative to ISO/TS 16949:2002.
• A single observed lapse in following one item of a company's quality management system.
