What is the definition of ISO 14001 nonconformance?

ISO 14000 registrars may have slightly different definitions of a major and minor nonconformance. Typically, a nonconformance is classified as major when there is a complete breakdown of an ISO 14001 system element, or when the nonconformance to ISO 14001 requirements poses a serious risk to the environment. A minor nonconformance is an isolated lapse in implementing or following any requirement of the ISO 14001 system. A major nonconformance means the system has a serious implementation flaw, a major requirement is not being met or it is clear to the auditor that the system is not functioning.  more
