当前对人类和家畜的影响 - 第二部分:特殊方面

[中文适用范围]： 本部分描述了频率高于100 Hz的正弦交流电流通过人体时产生的影响。给出了交流正弦电流与直流分量组合、带相位控制的交流正弦电流以及带多周期控制的交流正弦电流通过人体时的影响，但其适用频率范围仅限于15 Hz至100 Hz。提供了将纯正弦波适用频率扩展至150 kHz的方法，作为IEC 60479-1数据的补充。提供了检查随机复杂不规则波形的说明。本文件描述了人体在单个或多个连续单向矩形脉冲、正弦脉冲以及电容放电脉冲形式下的电流影响。规定值适用于0.1 ms至10 ms的脉冲持续时间。本文件仅考虑直接对体施加电流源产生的传导电流，不涉及因暴露于外部电磁场而在体内感应的电流。本基本安全出版物主要用于技术委员会按照IEC指南104和ISO/IEC指南51制定的原则编制标准。其不适用于制造商或认证机构。 [外文原描述]： IEC 60479-2:2019 describes the effects on the human body when a sinusoidal alternating current in the frequency range above 100 Hz passes through it. The effects of current passing through the human body for: – alternating sinusoidal current with DC components, – alternating sinusoidal current with phase control, and – alternating sinusoidal current with multicycle control are given but are only deemed applicable for alternating current frequencies from 15 Hz up to 100 Hz. Means of extending the frequency of applicability of pure sinusoids to a frequency of 150 kHz are given and means of examining random complex irregular waveforms are given. This document describes the effects of current passing through the human body in the form of single and multiple successive unidirectional rectangular impulses, sinusoidal impulses and impulses resulting from capacitor discharges. The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms. This document only considers conducted current resulting from the direct application of a source of current to the body, as does IEC 60479-1. It does not consider current induced within the body caused by its exposure to an external electromagnetic field. 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 first edition cancels and replaces IEC TS 60479-2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TS 60479 2:2017: a) change in status from Technical Specification to International Standard.
