What is the ISO/IEC 17021-1 standard?

The ISO/IEC 17021-1 standard sets out the requirements for bodies providing audit and certification of management systems (ISO 9001, ISO 14001, ISO 45001, ISO 27001, ISO 22000, etc.). Published in 2015, it is the global benchmark for accrediting certification bodies (CBs).

The standard covers impartiality, confidentiality, structural requirements, resource requirements (auditors, technical experts), information management requirements, process requirements (application, audit, decision, surveillance, certification cycle), and management system requirements of the CB itself.

ISO 17021-1 is supplemented by sector-specific parts: 17021-2 (environmental), 17021-3 (quality), 17021-4 (event sustainability), 17021-5 (asset management), 17021-6 (business continuity), 17021-7 (road traffic safety), 17021-9 (anti-bribery), 17021-10 (occupational health and safety). Each adds competence requirements for auditors specific to the relevant scheme.

Who is ISO/IEC 17021-1 for?

The standard targets certification bodies issuing certificates against management system standards: BSI, SGS, DNV, Bureau Veritas, LRQA, TÜV, NQA, Intertek, and dozens of smaller specialised CBs.

Why get certified?

ISO 17021 accreditation is mandatory to issue accredited certificates, conditions IAF recognition (so certificates are accepted worldwide), required for participation in regulated certification schemes, and builds market credibility as a certification body.

Frequently asked questions

Everything you need to know about ISO/IEC 17021-1

Difference between ISO 17021 and ISO 17065?
ISO 17021 applies to certification of management systems (ISO 9001, 14001, 27001, etc.). ISO 17065 applies to certification of products, processes, and services. The two are not interchangeable and require separate accreditation.
What are the sector-specific parts of ISO 17021?
Parts 2 to 10 add competence requirements for auditors of specific schemes: environmental (17021-2), quality (17021-3), event sustainability (17021-4), asset management (17021-5), business continuity (17021-6), road traffic safety (17021-7), anti-bribery (17021-9), and OH&S (17021-10).
How long does ISO 17021 accreditation take?
Expect 12 to 24 months from project kickoff to accreditation. The duration depends on scope, the number of schemes covered, and prior maturity.
How much does ISO 17021 accreditation cost?
For a mid-sized CB, expect $20,000 to $60,000 for initial accreditation depending on scope. Annual surveillance audits and witness audits add ongoing costs.
Can a CB be accredited under ISO 17021 AND ISO 17065?
Yes. Many large CBs (BSI, SGS, Bureau Veritas, DNV, LRQA, TÜV) hold both accreditations to cover management systems AND product certification.
