Nonconformance vs Nonconformity

Nonconformance is to be used when you perform quality control and the result is “not OK”. Nonconformance is about products and services, that is why clause 8.7 is “Control of nonconforming outputs”. The outputs are the products or services.

Nonconformity in clause 10.2 is to be used when you perform monitoring and measuring and the result is “not OK”. For example, when you evaluate the process “Manufacture product” and you realize that the rate of defects is above the maximum tolerated you have a nonconformity. This time the problem is not with the product but with process performance.

During audits, auditors only raise nonconformities even when it is about a particular product. For example, an auditor can raise a nonconformity because the nonconforming product is not correctly segregated. The concern of the auditor is not the product it is the system not working according to standard or procedure.

As my understanding,  Nonconformance = Defect, error parts (product or service). Nonconformity = Noncompliance. Is that correct?

Yes, I agree with your understanding.
