About This Item
IEC 61000-4-14:1999/AMD2:2009 is a focused EMC document for evaluating voltage fluctuation immunity for equipment with input current not exceeding 16 A per phase. As an amendment to the parent reference IEC 61000-4-14:1999, it is used as a supporting compliance reference rather than a standalone test method. For engineering teams, laboratories, and procurement reviewers, it helps define the technical basis for assessing how electrical equipment responds to voltage variations within documented testing workflows and conformity assessment activities.
Purpose of IEC 61000-4-14:1999/AMD2:2009
The purpose of IEC 61000-4-14:1999/AMD2:2009 is to support electromagnetic compatibility testing by clarifying the immunity evaluation of equipment subjected to voltage fluctuations. In practical terms, it is relevant where technical validation is needed to check whether equipment maintains expected operation under specified supply variations. Because it is tied to the parent document, it is commonly used to refine or update compliance interpretation, test planning, and engineering documentation for low-current electrical equipment.
Compliance applications of IEC 61000-4-14:1999/AMD2:2009
Organizations may use this amendment during laboratory evaluation, product qualification, and regulatory preparation for electrical equipment that must be assessed against EMC immunity requirements. It can be relevant in testing workflows for devices and systems with input current up to 16 A per phase, especially when documented evaluation is needed for technical review, certification support, or supplier approval. It also helps align test records and quality workflows with the parent reference when maintaining consistent compliance documentation.
Benefits of IEC 61000-4-14:1999/AMD2:2009
Using IEC 61000-4-14:1999/AMD2:2009 supports more consistent test interpretation and can reduce uncertainty during conformity assessment preparation. It helps teams compare results using a defined compliance reference, which is valuable for risk management, procurement review, and engineering validation. For manufacturers and test laboratories, it can improve technical consistency when documenting immunity performance, support operational reliability expectations, and provide clearer evidence during technical assessment or customer acceptance processes.
