ISO 18080-4:2015规定了一种使用水平机械摩擦的试验方法，该方法测量织物试样上的摩擦荷电静电势以及该电势衰减的时间。本试验方法适用于能够承受摩擦电荷的所有成分和结构类型的织物。 一些织物，例如低强度或松散结构的织物，可能无法承受本试验方法中使用的手动摩擦，或者可能给出错误的结果。在这种情况下，ISO 18080-1中描述的试验方法可用于评估静电倾向。 所述试验方法可能不适用于评估与人员安全和静电放电敏感设备保护相关的服装和服装材料。

ISO 18080-4:2015 specifies a test method using horizontal mechanical friction with measurement of friction-charged electrostatic potential on specimens of fabric and the time for that potential to decay. The test method is suitable for fabrics of all types of composition and construction that are capable of withstanding frictional charging. Some fabrics, e.g. fabrics of low strength or loose construction, may not be physically capable of withstanding the manual friction used in this test method or may give false results. In such cases, the test method described in ISO 18080？1 can be used to evaluate electrostatic propensity. The test method described may not be suitable for evaluating garments and garment materials in relation to safety of personnel and protection of electrostatic discharge sensitive devices.
