About This Item
IEC 61000-4-11:2020/COR2:2022 is a supporting corrigendum to the EMC testing reference for voltage dips, short interruptions, and voltage variations immunity tests for equipment with input current up to 16 A per phase. It matters for teams that rely on consistent technical documentation during verification activities, laboratory evaluation, and conformity assessment. As a correction to the parent document IEC 61000-4-11:2020, it helps ensure the underlying testing framework is interpreted and applied accurately in engineering documentation and compliance workflows.
What is IEC 61000-4-11:2020/COR2:2022?
This document is a corrigendum connected to IEC 61000-4-11:2020, not a standalone technical specification. Its role is to modify or clarify the parent EMC document covering immunity tests for voltage dips, short interruptions, and voltage variations on equipment with input current up to 16 A per phase. In practice, it is relevant where technical review, documented evaluation, and test method consistency are important for electrical equipment and related compliance reference files.
Applications of IEC 61000-4-11:2020/COR2:2022
IEC 61000-4-11:2020/COR2:2022 is typically used alongside the parent testing standard in EMC laboratories, product qualification programs, and compliance workflows for low-voltage electrical and electronic equipment. It may support test planning, procurement review, and internal quality assurance where immunity requirements and performance criteria must be checked against a controlled reference. Organizations preparing technical validation records or certification evidence often use corrigenda to confirm they are working from the correct version of the document set.
Why is IEC 61000-4-11:2020/COR2:2022 important?
For engineering and compliance teams, the value of this corrigendum is in improving document accuracy and reducing test interpretation risk. When immunity tests are used to evaluate how equipment responds to dips or interruptions in supply voltage, even small corrections can affect test setup, reporting, and regulatory preparation. IEC 61000-4-11:2020/COR2:2022 supports better operational consistency, helps protect conformity assessment results, and strengthens technical validation by keeping the parent reference aligned with the intended corrigendum.
