Overview
ISO/IEC 17021-1:2015 - "Conformity assessment - Requirements for bodies providing audit and certification of management systems - Part 1: Requirements" defines the principles and mandatory requirements for certification bodies that perform audit and certification of management systems. The standard ensures competence, consistency and impartiality in third‑party conformity assessment activities for any type of management system. It applies to organizations that operate or seek to operate a structured management system certification program.
Key topics and technical requirements
ISO/IEC 17021-1:2015 organizes requirements into logical clauses covering the full certification lifecycle:
- Principles: impartiality, competence, responsibility, openness, confidentiality, responsiveness to complaints and a risk‑based approach.
- General requirements: legal and contractual matters, certification agreements, responsibility for certification decisions and management of impartiality.
- Structural requirements: organizational structure, top management responsibilities and operational control.
- Resource requirements: competence criteria for personnel, auditor selection, use of external auditors/experts, personnel records and outsourcing.
- Information requirements: public information, certification documentation, use of marks, confidentiality and information exchange with clients.
- Process requirements: pre‑certification (application, review, audit programme, audit time), audit planning and conduct (opening/closing meetings, evidence gathering, findings), certification decision, surveillance, recertification, special audits, appeals and complaints.
- Management system requirements: options for a certification body’s own management system (general requirements or alignment with ISO 9001).
The standard also contains informative annexes (e.g., required knowledge and skills, evaluation methods, process flows) to support implementation.
