What is the difference between certificate of compliance and certificate of conformance.
Can anyone elucidate with references from code?

Suri,

Certificate of Compliance - A written statement attesting that the materials are in accordance with specified requirements.

Certificate of Conformance - A document signed or otherwise authenticated by an authorized individual certifying the items meet specified requirements.

Section III NCA

In a nutshell they are both basicallly the same.

Leem,

Sorry to correct you, they are not the same.

In NCA-3861 you may read that the Certificate of Compliance is the little brother of the CMTR, and can be used for small materials.

The COF can be a certification that some specified requirements are met. For Heat treatment of an Item for example.

Also in NCA-3680 the use of both CoC and CoF are addressed for certification of supports.

It is confusing indeed, but in section III the terms are not identical, and they are used in different context.

Interpretation QA-84-002
Subject:ANSI N45.2.10-1973 and ANSI/ASME NQA-1 1983 Edition

Question: Can a Certificate of Compliance be composed of a Certificate of Conformance and a Certified Test Report?

Reply:
Yes.
When defined under ANSI N45.2.10-1973, a Certificate of Compliance can be composed of a Certificate of Conformance, and a Certified Test Report could be a part of the required information to substantiate the statement. Documentation required with the Certificate of Compliance should be determined by the inquirer and his customer. It is further noted that during the preparation of ANSI/ASME NQA-1 (which supersedes and incorporates ANSI N45.2.10-1973), [b]term Certificate of Compliance is no longer used in ANSI/ASMENQA-1 and ANSI/AMSE NQA-2.

Leem,

well, good reply.

But I slam NCA-9000 definitions and the NCA-3860 wording on the table.
Ha, impressed?

Thank you gentlemen for the discussion.
I have the following understanding

1) In case of 'materials', Certificate of compliance can be given only for materials as stated in NCA-3862.1(g). For all other materials, CMTR is required.

2) Certificate of conformance can be issued to Items (again, here the item may include materials) or services

Yeah, that's it.

COC is the little brother of the CMTR, while a Cert of Conformance can be issued to certify conformance of something to some requirements.

And in NCA-3680 the use of both CoC and CoF are addressed for certification of SUPPORTS.
