Scope

This document is applicable to cable cutting devices to be used to verify that a cable is dead in accordance with the rules given in EN 50110. The following limits apply to the cable cutting devices: - pressure less than 1 000 bar or pressure (bar) x volume (l) less than 10 000; - fluid outside the categories listed in Article 13 Group 1 (explosive, extremely flammable, highly flammable, flammable (where the maximum allowable temperature is above flashpoint), very toxic, toxic, oxidizing) of the Pressure Equipment Directive 2014/68/EU. Cable cutting devices specified in this standard are for use on systems with nominal voltage up to 60 kV AC and nominal frequencies up to 60 Hz and shall only be suitable for operation by foot or by hand. This document does not cover motorised cable cutting devices. For devices to be used on systems with nominal voltages above 60 kV AC this standard should be used as a guide but additional requirements and tests shall be agreed between manufacturer and customer to provide for an equivalent level of safety. Cable cutting devices are not designed to be used on cables with special armour, or with steel wires or steel tapes more than 1 mm in diameter or thickness. The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.

Purpose

The previous version was published in 2010. This third edition includes the main following changes: - definitions revised; - references standards of were updated; - requirements and tests of the nominal voltages were extended to 60 kV; - only one method of determining the insulating hose assembly was chosen; - a mechanical endurance test was inserted; - dielectric test of insulating hose assembly was changed.
