Electrostatics - Part 4-9: Standard test methods for specific applications - Garments - Resistive characterization
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.

Electrostatics - Part 4-9: Standard test methods for specific applications - Garments
IEC 61340-4-9:2016 provides test methods for evaluating the electrical resistance of garments that contain surface conductive or dissipative components or materials used in the electronics industry for the control of electrostatic discharge. This standard defines procedures for measuring electrical resistance, including a system resistance test for garments that provide a ground path for personnel. This edition includes the following significant technical changes with respect to the previous edition: a) classification of three types of garments - static control garments, - groundable static control garments, and - groundable static control garment system; b) additional measurements according to the the garment type including cuff measurements, panel to groundable point, testing with a person in the garment system; c) sleeve to sleeve measurements allowed with probes or by hanging; d) additional recommended values for new garment types as set out in Annex A.
