This sentence "also known as compliance testing, or type testing" is not true, they are not synonyms. A type test is a special variant of conformity assessment, which means you test a few specimen and can show conformity for the whole series which is running of the production line with the same model number. There are factory tests, which check each manufactured item in the factory after it leaves the production lines. And there are site acceptance tests (SAT) where you test a larger installation at the point where it has been installed. "Compliance" usually refers to legal requirements: the "compliance officer" in a company is a kind of watchdog often with a legal background, taking care that there are no unlegal activities such as bribing, slush funds, anti-trust violations, etc. and installs structures that are intended to prevent them.
The assessment is the whole procedure, which may lead to different document types (self-declaration of the vendor, receiving inspection of the buyer, certificate = third party expert's report) whereas a test refers to the check of a single requirement. For example an electric appliance shall show that its work fine:
  1. within the declared frequency operating range
  2. within the declared voltage operating range
  3. within the declared range of harmonics.
In this example, there are three tests, but the whole procedure including what kind of equipment should be used for testing to guarantee repeatable results and some administrative requirements (how shall the test report look like) is the conformity assessment. The C-tests are part of the C-assessment. --Gunnar (talk) 15:06, 29 November 2020 (UTC)[reply]

Merge

Conformity assessment should be merged into this page. They are basically the same article. Rlsheehan (talk) 20:28, 21 November 2013 (UTC) Done[reply]

Actually Conformance Testing is only a component of Conformity Assessment. Certification (another component) is the process of product sampling (for testing), factory production control (FPC) audits and surveillance visits to ensure that what was tested is the same as the product delivered, with no changes which might affect its performance. Conformance Testing is not AKA Conformity Assessment. Conformity Assessment incorporates the services now called "TIC" (Testing, Inspection and Certification), as opposed to just testing.

I agree that conformity assessment (cf. with the relevant chapter in the International_Electrotechnical_Vocabulary) is the overall concept, that includes subroutines as the testing part. Regarding certification, this is one possible final result. See also "33 Aspects of conformity assessment", page 98, ISO/IEC DIR 2:2018: "All documents containing requirements for products, processes, services, persons, systems and bodies shall be written in accordance with the "neutrality principle", such that conformity can be assessed by a manufacturer or supplier (first party), a user or purchaser (second party), or an independent body (third party)." Certification is a third party assessment. --
