Energy management systems - Requirements for bodies providing audit and certification of energy management systems (ISO 50003:2021)

This document is intended to be used in conjunction with ISO/IEC 17021-1:2015. In addition to the requirements of ISO/IEC 17021-1:2015, this document specifies requirements reflecting the specific technical area of energy management systems (EnMS) that are needed to ensure the effectiveness of the audit and certification, while supporting the efforts of the organization to continually improve energy performance including energy efficiency, energy use and energy consumption, and the EnMS. In particular, this document addresses the additional requirements necessary for the audit process. It covers the planning process, theinitial certification audit, conducting the on-site audit, auditor competence, audit time and multi-site sampling. The structure of this document follows that of ISO/IEC 17021-1:2015. Annexes A and B are normative while Annexes C and D provide additional information to complement ISO/IEC 17021-1:2015. This document deals with EnMS audits for certification purposes, but it does not deal with energy audits where the purpose is to establish a systematic analysis of energy consumption and energy use, and which are defined in ISO 50002.
