"If you wish to maintain your certification to ISO*9001, you will need to upgrade your quality management system to the new edition of the standard and seek certification to it. You have a three-year transition period from the date of publication (September 2015) to move to the 2015 version. This means that,
after the end of September 2018, a certificate to ISO*9001:2008 will no longer be valid"
Would that mean certificates are valid until end of Sep 2018?
Ajit, as you know, ISO has no authority over validity of accredited certificates. That paper is promotional material, and, as you pointed out, it just muddle the waters. The ISO secretariat, that is certified to ISO 9001, should receive a nonconformity from it's CB (SQS) for failure to provide precise and accurate information (communication) about it's products.
The IAF is the entity that can determine deadlines for accredited certification. In the
resolutions from the Vancouver meeting, it clearly states:
IAF Resolution 2017-13 – (Agenda Item 9) Transitional Arrangements for the ISO 9001:2015 and ISO 14001:2015 - The General Assembly, acting on the recommendation of the Technical Committee, resolved that at the end of the transition period, 15 September 2018, all ISO 9001:2008 and ISO 14001:2004 certifications shall expire or be withdrawn.
So,
technically, if an organization does not have it's certificate to the 2015 Edition
issued by the end of the day (the 15th), the old certificate should be deemed invalid.
In practical terms, for the most part, that is an issue between the registrants and the stakeholders that demand them to be certified. If a customer accepts an expired certificate for whatever length of time beyond their expiration, nothing anyone can do about that.
