ISO 20495:2018规定了皮肤电阻测量装置的性能和试验方法。 ISO 20495:2018适用于皮肤电阻测量设备，通过该设备以非侵入方式将电信号施加在人体的穴位或体表的特定点上，以检测身体的电阻。 ISO 20495:2018不适用于测试结果医学分析的软件或功能。 附件A中给出了其他指导和基本原理。

ISO 20495:2018 specifies performance and test methods for skin electrical resistance measurement devices. ISO 20495:2018 is applicable to skin electrical resistance measurement devices through which an electrical signal is applied on acupuncture points of the human body or specific points of the body surface in a non-invasive way so as to detect the resistance of the body. ISO 20495:2018 is not applicable to software or functions for medical analysis of the test results. Additional guidance and rationale are given in Annex A.
