前言

本标准是根据国际电工委员会(IEC)出版物IEC1294(1993年第一版)绝《缘液体局部放电起始

电压测定试验程序》制定的，在技术内容上与其等效。因原文第5章内容在本标准第7章中已详细叙

述，故在本标准中删除原文第5章内容。

本标准的附录A为提示的附录。

本标准由中华人民共和国机械工业部提出。

本标准由全国绝缘材料标准化技术委员会归口。

本标准起草单位:西安交通大学。

本标准起草人:曹晓珑、徐阳、陈文桂。

本标准1999年10月首次发布。

本标准委托全国绝缘材料标准化技术委员会负责解释。

IEC前言

1)IEC(国际电工委员会)是一个由各国家电工委员会((IEC国家委员会)组成的世界性标准化组

织。IEC的目的是促进电气和电子领域内所有标准化问题的国际合作。为此目的，除了其他活动外，IEC

还出版国际标准并把制定国际标准的任务委托给各技术委员会。任何对所研究问题表示关切的IEC国

家委员会都可以参加此制定工作，与IEC保持联络的国际的、政府的和非政府的组织也可参加此制定

工作。根据两组织间协议确定的条件，IEC与国际标准化组织(ISO)保持密切合作。

2)IEC关于技术问题的正式决议或协议，是由对这些技术问题特别关切的各国家委员会代表组成

的技术委员会制定的。对其中所研究的问题，尽可能地表达国际上一致意见。

3)这些决议或协议以标准、技术报告或指南的形式出版，向国际上推荐使用并在这个意见上为各

国家委员会所接受。

4)为了促进统一，IEC各国家委员会承诺，在其国家标准或地区标准中，尽可能明白无误地采用

IEC国际标准。IEC标准与相应国家标准或地区标准之间的任何差异，应在国家标准或地区标准中明确

指出。

IEC技术委员会的主要任务是制定国际标准。在特殊情况下，某技术委员会可以建议出版下述三种

形式之一的技术报告

形式1:当历经反复努力之后，就出版某一国际标准还是得不到所需要的支持时;

形式2:当所研究的问
