What it covers
What it means in practice
Checking a company's certificate
ISO does not hold a register of certified companies — certificates are issued by independent certification bodies. Accredited certificates can be looked up in IAF CertSearch, the International Accreditation Forum's global database, which shows the certificate status, scope, certified sites, the issuing body and its accreditation body.
Free public access is limited to a small number of lookups, which is why we do not publish bulk certificate data for this standard. Where a manufacturer publishes its own certificate we record that as a manufacturer statement, clearly labelled, rather than as something we independently verified.
