Major nonconformity

A major nonconformity is an audit finding that a mandatory requirement is missing or has broken down, serious enough to block or suspend an ISO certificate.

Typical examples are a clause that is not implemented at all, such as no internal audit having taken place, a control declared applicable in the Statement of Applicability with no evidence it operates, or several minor findings that together show a process has failed. The certificate cannot be recommended until the certification body has verified the corrective action, often in a follow-up visit.
