New IAF Mandatory Document on audit duration for EMS, QMS & OH&S applies today

Today (7 May 2020) sees the application of the International Accreditation Forum (IAF) Mandatory Document, which describes additional controls for Certification Bodies to apply for the determination of audit duration within the Certification processes.

As outlined in an earlier post: New IAF Mandatory Document on audit duration for EMS, QMS & OH&S published, the document is mandatory for the consistent application of the audit duration with reference to the relevant clauses of ISO/IEC 17021-1:2015 for audits of ISO 9001:2015, ISO 14001:2015 & ISO 45001:2018 management systems. All clauses of ISO/IEC 17021-1 continue to apply and this document does not supersede any of the requirements in that standard.

The International Accreditation Forum (IAF), which is the global network of accreditation bodies and other organisations involved in conformity assessment activities, has published a new Mandatory Document applicable to Management System Standards (MSS) certification ,such as ISO 14001:2015 and ISO 9001:2015.

The document was published on 7 May 2019 with a number of clarifications on the determination of audit time.

The Application Date for this Mandatory Document is 7 May 2020, when the National Accreditation Body (NAB) will expect the obligations of this Mandatory Document to have been embedded within the Certification Body and its Management System.
