Full definition
Third-party verification by an accredited certification body (registrar) that an organization's management system meets the requirements of a specified international standard, providing external credibility to customers, regulators, and stakeholders. Major certifiable management system standards: ISO 9001 (quality management — the most widely held, with over 1 million certificates worldwide), ISO 14001 (environmental management), ISO 45001 (occupational health and safety — replaced OHSAS 18001), IATF 16949 (automotive quality — mandatory for OEM suppliers), ISO 22000 (food safety), and ISO 13485 (medical devices). Certification process: gap analysis → implementation → internal audit → management review → Stage 1 audit (documentation review) → Stage 2 audit (on-site verification) → certificate issued. Validity: 3 years with annual surveillance audits. Accreditation: the certification body itself must be accredited by a national body (ANAB, UKAS, DAkkS, EMA in Mexico) that verifies the registrar's competence. Cost: $5,000-50,000+ depending on organization size, scope, and standard. For industrial rubber suppliers, ISO 9001 certification is increasingly a minimum requirement for B2B customers, especially in automotive, mining, and oil/gas sectors.
