规定了测定所有类型地板覆盖物和已安装地板的电阻的试验方法，其对地电阻、点对点电阻和垂直电阻介于104 W和1013 W之间。在受控环境条件下进行的实验室评估可用于分类或质量控制目的。在不受控制的环境条件下对已安装的地板进行测试，可用于确定正确的安装，或作为正在进行的系统验证的一部分。 重要变更仅指试验方法规范，不包含分类或性能要求；试验方法涉及电阻测量，规定的设备更符合IEC 61340的其他部分

Specifies test methods for determining the electrical resistance of all types of floor coverings and installed floors with resistance to ground, point-to-point resistance and vertical resistance of between 104 W and 1013 W. Laboratory evaluations carried out under controlled environmental conditions can be used for classification or quality control purposes. Tests on installed floors under uncontrolled ambient conditions can be used to determine correct installation or as part of an ongoing system verification. The important changes refer only to the specification of test methods but do not contain classification or performance requirements; the test methods refer to resistance measurement, and the specified equipment comply more with those of the other parts of IEC 61340
