If a company is ISO 9001: 2015 certified, is it revocable?
From Jim Werner:
A company can indeed have its certification revoked. Being certified means the company has established a qualify management system that meets the requirements of ISO9001:2015. The failure of the company to continue to meet those requirements can result in de-certification.
From George Hummel:
Most CBs will revoke a certificate if the client does not answer an audit non-conformance. Their contract may define other instances. The questioner should review his or her organization’s contract.
From Charles Cianfrani:
Certified companies receive surveillance audits periodically. If the company fails to maintain compliance with ISO 9001:2015 requirements, eventually (after a series of intermediary steps related to resolution of nonconformity have been unsatisfactorily pursued) their certification can be voided.
