    EnMS Terms and Definition are vital part of documentation and operation for reaching common understandings among the workforce. Acronyms are practical to tidy up document phrases as well as to enhance communication within the EnMS operation in daily conversation.

    ISO 50001 promotes common terminologies…

    This page is to provide terms, definitions and acronyms used in this website as well as in our documents, guidebooks and templates in order for you to quickly get familiarized with EnMS contents aiming to strengthen your confidence level in our website contents and our documents. The majority of EnMS Terms and Definition were taken from:
    • International Standard ISO 50001:2011(E), Energy management system-Requirements with guidance for use
    • International Standard ISO 19011:2002, Guidance on the Principles of Auditing

    Terms / Acronyms Definitions
    audit systematic, independent and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled

    NOTE 1:
    Internal audits, sometimes called first-party audits, are conducted by, or on behalf of, the organisation itself for management review and other internal purposes, and may form the basis for an organisation's self-declaration of conformity. In many cases, particularly in smaller organisations, independence can be demonstrated by the freedom from responsibility for the activity being audited.

    NOTE 2:
    External audits include those generally termed second- and third-party audits. Second-party audits are conducted by parties having an interest in the organisation, such as customers, or by other persons on their behalf. Third-party audits are conducted by external, independent auditing organisations, such as those providing registration or certification of conformity to the requirements of ISO 9001, ISO 14001 or ISO 50001.

    NOTE 3:
    When an energy management system and an environmental management system are audited together, this is termed a combined audit.

    NOTE 4:
    When two or more auditing organisations cooperate to audit a single auditee, this is termed a joint audit.
