About This Item
IEC 62153-4-9:2018/AMD2:2024 is a supporting amendment to the parent document IEC 62153-4-9:2018, addressing the triaxial method used to measure coupling attenuation of screened balanced cables for electromagnetic compatibility evaluation. For engineering teams, test laboratories, and compliance reviewers, it helps clarify how a specific EMC-related measurement approach should be applied and interpreted within documented testing workflows. As an amendment, it is best used alongside the parent reference when performing technical review, verification activities, or conformity assessment preparation.
Purpose of IEC 62153-4-9:2018/AMD2:2024
The purpose of IEC 62153-4-9:2018/AMD2:2024 is to update and modify the parent test method covering coupling attenuation measurement for screened balanced cables using a triaxial setup. In practical terms, it supports more consistent laboratory evaluation of cable screening performance in EMC contexts, where repeatable measurement conditions are important for documented evaluation and technical validation. Organizations may use it to align internal test procedures, review acceptance criteria, or maintain operational consistency across product development and compliance workflows.
Compliance applications of IEC 62153-4-9:2018/AMD2:2024
This amendment is relevant where screened balanced cables are assessed as part of EMC testing, product qualification, or supplier verification. It may be used by laboratories, cable manufacturers, procurement teams, and conformity assessment groups that need a reliable technical document for coupling attenuation measurements in controlled test environments. The reference is particularly useful when evidence is needed for engineering documentation, regulatory preparation, or technical compliance files associated with electrical equipment and communication cabling.
Benefits of IEC 62153-4-9:2018/AMD2:2024
Using IEC 62153-4-9:2018/AMD2:2024 alongside the parent document can improve testing consistency and reduce ambiguity in EMC measurement practice. That supports quality workflows, comparison of test results across laboratories, and more defensible performance evaluations during procurement or design review. For organizations handling conformity assessment or risk management, the amendment can also help strengthen technical assessment records and reduce the chance of misalignment between internal procedures and the referenced testing standard.
