About This Item
IEC 61000-4-11:2020/COR1:2020 is a corrigendum linked to the EMC testing reference IEC 61000-4-11:2020, addressing voltage dips, short interruptions, and voltage variations immunity tests for equipment with input current up to 16 A per phase. It is relevant when teams need to confirm that their technical document set, test plans, or procurement files align with the corrected wording of the parent publication. For engineering review, laboratory evaluation, and conformity assessment, IEC 61000-4-11:2020/COR1:2020 helps support accurate interpretation of immunity requirements and test execution.
Purpose of IEC 61000-4-11:2020/COR1:2020
The purpose of IEC 61000-4-11:2020/COR1:2020 is to modify or clarify the parent EMC immunity testing text rather than replace it as a standalone testing standard. In practice, it supports technical assessment of equipment exposed to voltage dips, short interruptions, and voltage variations, which are common concerns in power-quality related verification activities. By using the corrigendum alongside IEC 61000-4-11:2020, organizations can reduce ambiguity in documented evaluation, improve test consistency, and better align engineering documentation with the intended compliance reference.
Compliance applications of IEC 61000-4-11:2020/COR1:2020
This corrigendum is typically used in compliance workflows involving EMC testing laboratories, product qualification teams, and procurement or certification reviews for electrical equipment within the stated input current range. It is most useful where test procedures, reports, or internal specifications cite IEC 61000-4-11:2020 and must reflect the corrected text for regulatory preparation or conformity assessment. For manufacturers and test houses, IEC 61000-4-11:2020/COR1:2020 can be part of the controlled document set used during technical validation and report generation.
Benefits of IEC 61000-4-11:2020/COR1:2020
Using IEC 61000-4-11:2020/COR1:2020 helps teams maintain accuracy in testing workflows and reduce the risk of relying on superseded or unclear wording. That is valuable for safety-related technical review, interoperability expectations, and quality assurance across design verification and certification preparation. For procurement and compliance teams, the corrigendum supports cleaner traceability between the parent document and the version used in documented evaluation. It also helps preserve consistency in laboratory procedures, which can improve confidence in immunity test outcomes and risk management decisions.
