About This Item
IEC 62271-100:2021/COR2:2022 is a corrigendum tied to Corrigendum 2 - High-voltage switchgear and controlgear - Part 100: Alternating-current circuit-breakers, supporting technical review and document control for high-voltage circuit-breaker work. It is relevant where engineering teams, laboratories, and procurement functions need to align their technical documentation with the corrected parent reference, IEC 62271-100:2021. In compliance workflows, a corrigendum helps reduce ambiguity, improve consistency, and support accurate conformity assessment against the underlying requirements for alternating-current circuit-breakers.
What is IEC 62271-100:2021/COR2:2022?
This document is a supporting correction to the parent publication for high-voltage switchgear and controlgear, Part 100, which addresses alternating-current circuit-breakers. IEC 62271-100:2021/COR2:2022 is therefore not a standalone technical specification, but a modifying reference that should be read together with IEC 62271-100:2021. In engineering and compliance settings, corrigenda are used to maintain accuracy in the technical document set, support documented evaluation, and help ensure that testing workflows and specifications reflect the intended text.
Applications of IEC 62271-100:2021/COR2:2022
Organizations may use this corrigendum when updating procurement files, design records, test plans, or compliance dossiers related to high-voltage alternating-current circuit-breakers. It is particularly relevant during technical assessment, laboratory evaluation, and verification activities where the parent document is being cited as a compliance reference. For utilities, manufacturers, test laboratories, and engineering consultants, IEC 62271-100:2021/COR2:2022 supports operational consistency by helping ensure that the correct edition and correction set are used in review, certification preparation, and quality workflows.
Why is IEC 62271-100:2021/COR2:2022 important?
Corrigenda matter because even small textual corrections can affect interpretation, testing consistency, and conformity assessment outcomes. IEC 62271-100:2021/COR2:2022 helps teams reduce risk by keeping technical documentation aligned with the corrected parent standard for high-voltage circuit-breakers. That is valuable in safety-focused electrical equipment projects, where accuracy supports engineering validation, procurement review, and regulatory preparation. Using the correct supporting reference can also improve audit readiness and reduce the chance of inconsistencies across specifications, test reports, and acceptance criteria.
