Live working - Ladders of insulating material

Is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and 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.

This standard concerns only ladders made of synthetic material.

These ladders are used to provide access, generally on overhead line structures, and to facilitate live working, either hot stick, barehanded, or a combination of both.
