IEC 61477:2009给出了与带电作业工具、装置和设备的规格、制造、选择、应用和维护相关的最低要求。它提供了对技术人员有用的信息类型，以便更安全地使用工具、装置和设备。这类信息包括: -工具、装置和设备的特性； -其使用条件； -其维修条件； -其储存和运输条件。 此类信息可以在标准、制造商的使用说明以及公司为其员工制定的内部法规中给出。此类信息应通过工作方法完成，不在本标准范围内。IEC 61477的第二版取消并取代了2001年发布的第一版及其修正案1(2002)和修正案2(2004)。 2009年4月更正的内容已纳入本副本。

It provides the type of information which is useful to skilled persons in order to make the use of tools, devices and equipment safer. This type of information includes:
- the characteristics of tools, devices and equipment;
