IEC 62040-1:2017/COR1:2019

IEC 62040-1:2017/COR1:2019 is a corrigendum linked to Corrigendum 1 - Uninterruptible power systems (UPS) - Part 1: Safety requirements, issued to support the parent document IEC 62040-1:2017. For engineering teams, test laboratories, and procurement reviewers, it serves as a technical correction reference that helps keep documentation aligned with the safety requirements intended for UPS equipment. In compliance workflows, such supporting documents are often important for accurate technical review, conformity assessment, and controlled use of the correct edition.

What is IEC 62040-1:2017/COR1:2019?

This document is a corrigendum rather than a standalone requirements standard, so its role is to modify or clarify the parent publication IEC 62040-1:2017. Based on the title, the parent document addresses safety requirements for uninterruptible power systems, which are widely used in electrical equipment and critical power applications. In practice, IEC 62040-1:2017/COR1:2019 is relevant when organizations need to verify that their engineering documentation, test files, or compliance reference set reflects the corrected safety text.

Applications of IEC 62040-1:2017/COR1:2019

IEC 62040-1:2017/COR1:2019 is commonly used in technical review and document control for UPS-related projects, especially where safety validation, procurement checks, or certification preparation depend on the exact wording of the parent standard. It may support laboratory evaluation, product evaluation, and conformity assessment activities for power continuity systems used in industrial, commercial, or infrastructure settings. Teams responsible for regulatory preparation and quality workflows often reference corrigenda to maintain consistency across design records, test plans, and compliance submissions.

Why is IEC 62040-1:2017/COR1:2019 important?

This corrigendum matters because even small editorial or technical corrections can affect safety interpretation, testing workflows, and conformity assessment outcomes for UPS equipment. Using the corrected reference helps reduce risk during engineering validation and supports more reliable technical assessment across internal and external reviews. For procurement and compliance teams, it improves confidence that the documented requirements set is complete and current, which can be important for operational consistency, audit readiness, and controlled product acceptance decisions.

• Supporting correction reference for the safety requirements in IEC 62040-1:2017
• Useful for document control, technical review, and compliance workflow alignment
• Relevant to UPS safety validation, testing preparation, and conformity assessment
• Helps maintain consistency between engineering records and the corrected parent text
