How is conformity assessment carried out?
The conformity assessment procedure consists of a series of 3 functions that are needed to demonstrate that specified requirements are fulfilled:
Selection: The object of the assessment (i.e. product, process, system, person or body); the specified requirements; the procedure to be used for the determination; sampling methods, etc.
Determination: Types of determination activities are testing, inspection, audit, peer assessment
Review and attestation: Reviewing evidence arising from the determination and making a decision as to whether or not the object of conformity assessment has been reliably demonstrated to fulfill the specified requirements. Decision communicated as a ”statement of conformity”.

NOTE: The terms “declaration of conformity”, “certification” and “accreditation” are types of attestations having specific meanings.
