Conformity assessment vocabulary

A claim of conformity is incomplete until its object and requirements are clear. The object might be a product, service, process, organization, person or a particular statement. Testing, inspection and certification describe different ways of generating or evaluating evidence; accreditation concerns the competence of a body performing assessment. ISO/IEC 17000 provides general terms and principles for this field. Careful language allows a reader to understand what was assessed and what has actually been demonstrated.

Terminology connects the technical activity with the resulting communication. A test report records results under a method; a certification decision produces an attestation within a defined scheme; a declaration identifies the party taking responsibility for a claim. These documents may refer to the same product while carrying different meanings. The family is not a set of product acceptance limits. Its publication identity and general vocabulary scope are available in ISO Open Data.

The selected record is ISO/IEC 17000:2020 (edition 2, published 2020-05-26). It was checked on 19 October 2026 in ISO Open Data. ISO/IEC 17000:2020 is the recorded vocabulary publication. Its terminology is not a substitute for definitions in a specific legal instrument. The WTO TBT Agreement, for example, defines terms for its own purposes. The applicable source must be named when the meaning of a claim or obligation depends on that distinction.

Consider a supplier who says an item is certified because a laboratory tested a sample. The buyer needs to ask whether there was a separate certification scheme and decision, or only a test report. Conversely, a declaration can be a meaningful part of a regulatory route without being independent third-party certification. The task is to identify the responsible party and process, not to rank every document by its title. Clear purchasing language specifies the required evidence and avoids asking suppliers for a certificate that the relevant procedure never produces.

The WTO TBT Agreement distinguishes technical regulations, standards and conformity assessment procedures for its legal framework. Its definition of a standard refers to non-mandatory compliance, while a technical regulation is mandatory. A national system can use terminology differently in its own legislation. The vocabulary page therefore cannot settle a legal classification by itself. A precise account states the jurisdiction, governing document and purpose for which a term is being used.

For any assurance statement, identify five elements: the object, specified requirements, assessment activity, responsible party and resulting statement. Then ask about the sample or scope, the date and the means of verification. Is accreditation claimed for the issuing body or mistakenly for the product? Is a management system certificate presented as proof of an individual item’s performance? These questions make the evidence understandable before technical details are compared and help expose gaps hidden by familiar abbreviations.

Terminological precision does not by itself prove technical conformity, but it prevents avoidable misunderstandings about evidence. Two records can both be legitimate while supporting different conclusions. A report may address a tested sample; a certificate may cover a defined product family; a declaration may carry the manufacturer’s responsibility under a specific legal route. This reference explains those distinctions through public sources and original examples. It does not reproduce the standard’s definitions or decide the legal effect of a particular document.

Follow testing and calibration, inspection bodies and product certification bodies for the different evidence behind each activity. Accreditation bodies adds the provider competence layer. The standards, regulations and guidance study explains why the document specifying a requirement and the procedure demonstrating conformity are separate parts of the same decision.

The vocabulary reference supplies terminology, not a registry of approved products or bodies. Claims about a particular certificate, accreditation or legal approval require the issuer’s or authority’s own records. The full competence standard remains available from its publishers. A correction request can identify a disputed statement, the document and supporting official evidence.
