本国际标准涵盖用于交流或直流电气装置带电作业的伸缩杆和伸缩测量杆，交流电压为1000 V及以上，直流电压为1500 V及以上。伸缩杆设计用于接受符合适当带电作业标准的附件，以及这些附件，可用于远距离对带电部件执行机械作业。本标准涵盖的工具（伸缩杆和伸缩测量杆）可在干燥条件下使用，但也可在非常潮湿的条件下使用，使用适当的工作程序。 伸缩杆还设计用于接受符合适当带电作业标准的诊断设备，并用于使诊断设备到达待测试装置的零件。伸缩式测量杆或带有刻度的伸缩杆用于测量带电部件之间的距离。本标准不包括伸缩钩杆。本标准不包括伸缩粘结杆和根据用户要求设计的任何其他特殊伸缩杆。

This International Standard covers telescopic sticks and telescopic measuring sticks to be used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c.The telescopic sticks are designed to accept attachments that meet appropriate live working standards and, together with these attachments, may be used to perform mechanical work on live parts at a distance.The tools (telescopic sticks and telescopic measuring sticks) covered by this standard are for use under dry conditions but could also be used under very humid conditions, using appropriate working procedures. Telescopic sticks are also designed to accept diagnostic devices that meet appropriate live working standards and are used to make the diagnostic devices reach parts of an installation to be tested. Telescopic measuring sticks, or telescopic sticks equipped with graduations, are used to measure distances to or between live parts.Telescopic hook sticks are not covered by this standard. Telescopic bonding sticks and any other speciality telescopic sticks designed at the request of users are not covered by this standard.
