IEC 62271-100:2021/COR1:2021

IEC 62271-100:2021/COR1:2021 is a corrigendum to the document covering high-voltage switchgear and controlgear, specifically alternating-current circuit-breakers. In practical workflows, it supports technical review by clarifying or correcting the parent reference, IEC 62271-100:2021, rather than replacing it as a standalone engineering specification. For teams involved in procurement, conformity assessment, or test planning, this reference helps maintain document accuracy and supports reliable interpretation of requirements for high-voltage circuit-breaker applications.

Purpose of IEC 62271-100:2021/COR1:2021

The purpose of IEC 62271-100:2021/COR1:2021 is to provide a formal correction to the parent publication for alternating-current circuit-breakers used in high-voltage switchgear and controlgear systems. Corrigenda are typically consulted during engineering documentation review, verification activities, and compliance preparation to ensure that technical references reflect the intended requirements. For organizations managing electrical equipment specifications, it helps reduce ambiguity in technical assessment and supports more accurate use of the parent document during quality workflows.

Compliance applications of IEC 62271-100:2021/COR1:2021

IEC 62271-100:2021/COR1:2021 is relevant when users need to confirm the current corrected text associated with high-voltage alternating-current circuit-breakers. It may be applied in laboratory evaluation, regulatory preparation, procurement checks, and documented evaluation of switchgear project requirements. Engineering and compliance teams often use corrigenda to align test plans, technical files, and internal specifications with the authoritative source. In practice, it supports technical validation where accuracy in the parent reference is important for operational consistency and conformity assessment.

Benefits of IEC 62271-100:2021/COR1:2021

Using IEC 62271-100:2021/COR1:2021 helps organizations maintain safety-focused documentation and reduce risk from outdated or incorrect references. For teams handling high-voltage equipment, even a corrigendum can be important for interoperability, testing consistency, and engineering validation. It supports procurement decisions by giving buyers and specifiers a more reliable compliance reference, while also helping laboratories and manufacturers keep test procedures aligned with the corrected text. This contributes to stronger quality assurance and smoother conformity assessment preparation.
