What is the validity period of the Certificate for Internal Auditor (for example acc. to ISO/TS 16949)? And what is behind that (legal basis, any norm requirement)? I mean how long (how many years) Auditor can carry internal audits?
The management system standards do not define validity of the certificates for internal auditors and they don't even require from internal auditors to have such certificates. Although it does not requires the certificate and neither it limits the validity of the certificate, IATF 16949 (former ISO/TS 16949) has requirements regarding maintenance and improvement of competence of internal auditors.
The standard requires organization to define minimum number of audits per year performed by each internal auditor and it expects from the auditors to maintain knowledge of relevant requirements based on internal changes (e.g. processes, technology, product technology) and external changes (changes in the standard, core tools, customer specific requirements).
i'm Certified internal auditor for IATF 16949:2016 but not having ISO 9001:2015 internal auditor certificate , can i do internal ISO 9001:2015 audit (Recently job change to IATF to ISO company.i think IATF certificate is enought to do ISO 9001.....right ? ).
