ISO 9001
Definition
The international standard for quality management systems, certified by independent certification bodies.
ISO 9001 sets requirements for a quality management system: documented processes, customer focus, internal audits, corrective action and continual improvement. Certificates are issued by certification bodies, which should themselves be accredited by a national accreditation body such as NABCB in India, UKAS in the UK or ANAB in the US.
ISO 9001 shows that a company manages its processes, not that a particular product meets a specification. You can check many certificates in the IAF CertSearch database or with the certification body named on the certificate.
