About This Item
IEC 61000-3-3:2013/AMD2:2021/COR1:2022 addresses corrigendum and amendment updates linked to the EMC requirements for limiting voltage changes, voltage fluctuations, and flicker in public low-voltage supply systems. For engineering teams, laboratories, and compliance reviewers, it is a useful technical document for checking how the parent requirements are modified or clarified for equipment with rated current ≤16 A per phase and not subject to conditional connection. The reference is often relevant during technical review, conformity assessment, and regulatory preparation.
IEC 61000-3-3:2013/AMD2:2021/COR1:2022 standard overview
This document supports IEC 61000-3-3:2013 as a modifying reference, rather than a standalone technical specification. Its role is to adjust or correct the parent EMC framework that addresses voltage changes, voltage fluctuations, and flicker created by low-current equipment connected to public low-voltage networks. Edition 3 and the 2022 corrigendum context are important for organizations maintaining documented evaluation practices, testing workflows, and product compliance records that rely on the latest technical wording.
Applications of IEC 61000-3-3:2013/AMD2:2021/COR1:2022
IEC 61000-3-3:2013/AMD2:2021/COR1:2022 is typically used when reviewing products that connect to public low-voltage supply systems and may affect supply stability through voltage variation or flicker. It is relevant to electrical equipment assessment, EMC document control, laboratory evaluation, and procurement checks where the latest amendment and corrigendum need to be reflected in internal specifications. It may also support manufacturers, test houses, and certification teams working on technical validation and evidence packages for market access.
Why IEC 61000-3-3:2013/AMD2:2021/COR1:2022 matters
Keeping this reference in scope helps reduce compliance gaps and improves consistency across engineering documentation, test reports, and conformity assessment files. Because it modifies the parent document, it can affect how voltage fluctuation and flicker requirements are interpreted in quality workflows and verification activities. For organizations managing risk management and technical compliance, using the current amendment and corrigendum helps align product evaluation with the expected EMC framework and supports more reliable procurement and approval decisions.
