 Where major nonconformities are identified, the organization presents an improvement plan to the certification body (e.g., corrective action reports showing how the problems will be resolved); once the certification body is satisfied that the organization has carried out sufficient corrective action, it issues a certificate.The certificate is limited by a certain scope (e.g., production of golf balls) and displays the addresses to which the certificate refers.An ISO 9001 certificate is not a once-and-for-all award but must be renewed, in accordance with ISO 17021, at regular intervals recommended by the certification body, usually once every three years.
