TL 9000 Certification Bodies
Certification Bodies (CBs), also called Registrars, contract with organizations to audit their processes against TL 9000 requirements. If the organization is found to be in conformance with TL 9000 requirements, the CB issues a certificate of conformance, normally good for three years.
The CB will perform regular surveillance audits, at least one per year, and perform a re-certification audit the end of the three-year term.
The CB must be accredited by one or more of TIA QuEST Forum's authorized Accreditation Bodies (ABs). If a CB is accredited by more than one of TIA QuEST Forum's authorized ABs, then a TL 9000 registration must also choose the AB and enter the name on the TL 9000 registration profile.
