IEC 61340-4-1:20 03+A1:2015规定了确定所有类型的地板覆盖物和已安装地板的电阻的测试方法，其对地电阻、点对点电阻和垂直电阻在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地板进行测试可用于确定正确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；试验方法参考电阻测量，规定的设备更符合IEC 61340其他部分的设备。 本合并版本由第二版（2003年）组成 及其修正案1（2015）。因此，无须在 本出版物的补充。

IEC 61340-4-1:2003+A1:2015 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. This consolidated version consists of the second edition (2003) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.
