Anotace

IEC 61340-4-9:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61340-4-9:2024 edition 3.0 and the previous IEC 61340-4-9:2016 edition 2.0. Furthermore, comments from IEC TC 101 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61340-4-9:2024 provides test methods for measuring the electrical resistance of garments used for static control applications. These test methods can be used for evaluating outer garments that are homogenously conductive or homogeneously dissipative, or that utilize surface conductive or surface dissipative components or elements. NOTE It is possible that the test methods defined in this document will not be able to measure materials with buried conductive layers. This third edition includes the following significant technical changes with respect to the previous edition: a) IEC 61010-1 and IEC 61010-2-030 added as requirements for measurement equipment; b) testing voltage range for personnel ground path changed from "7 V DC to 30 V DC" to "7 V DC to 100 V DC"; c) cleaning requirements changed from a minimum of five cycles of cleaning to a minimum of three cycles of cleaning; d) moderate humidity requirements deleted; e) figures replaced with generic drawings.
