参考IEC 60479-5中给出的阈值，提供常规接触电压限值的使用指南。考虑了不同的生理效应、环境条件、接触条件等。 本规范仅讨论50/60 Hz正弦交流电压和无明显交流分量的纯直流电压。 本说明书不考虑身体部位或医疗应用的浸没。 触摸电压限值供技术委员会用作确定其特定限值的指南。 本基本安全出版物主要供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则编制标准时使用。 它不适用于制造商或认证机构 技术委员会的职责之一是，在适用的情况下，在编制出版物时使用基本安全出版物。除非相关出版物中明确提及或包含，否则本基本安全出版物的要求、试验方法或试验条件不适用。 第二版取消并取代1992年作为技术报告发布的第一版。它构成了一个技术修订版，现在具有技术规范的状态。 与上一版相比，主要变化如下: -各种常规接触电压限值的最大接触面积建议； -通过人体引入不同的电流通路，用于选择传统的接触电压限值； -引入与惊跳反应电流阈值、释放电流阈值和心室颤动电流阈值相对应的常规接触电压限值； -其他传统接触电压限制的接触面积插值的可能性。 根据IEC指南104和ISO/IEC指南51，其具有基本安全出版物的状态。

Provides guidance on the use of conventional touch voltage limits with reference to thresholds given in IEC 60479-5. Consideration is given to different physiological effects, environmental conditions, contact conditions, etc. This specification only discusses voltages for sinusoidal a.c. at 50/60 Hz and pure d.c. having no significant a.c. component. This specification does not consider immersion of body parts or medical applications. Touch voltage limits are for use by technical committees as guidance for the determination of their own specific limits. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. This second edition cancels and replaces the first edition which was issued as a technical report in 1992. It constitutes a technical revision and now has the status of a technical specification. The main changes with respect to the previous edition are listed below: - proposal of maximum contact areas for various conventional touch voltage limit; - introduction of different current pathways through the human body for the selection of conventional touch voltage limit; - introduction of conventional touch voltage limit corresponding to the startle reaction current threshold, the inability of let-go current threshold and the ventricular fibrillation current threshold; - possibility of interpolation on contact area for other conventional touch voltage limits. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51.
