IEC 61340-4-9:20 24提供了测量用于静电控制应用的服装的电阻的测试方法。这些测试方法可用于评价均匀导电或均匀耗散的外衣，或利用表面导电或表面耗散部件或元件的外衣。 笔记？本文件中定义的测试方法可能无法测量具有埋入导电层的材料。 与上一版相比，第三版包含以下重大技术变更: a)增加IEC 61010-1和IEC 61010-2-030作为测量设备的要求； b)人员接地路径测试电压范围由“7 V DC至30 V DC”变更为“7 V DC至100 V DC”； c)清洁要求从最少五个清洁周期变为最少三个清洁周期； d)删除中等湿度要求； e)用通用附图替换的附图。

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.
