- 5 - EN 50340:20011ScopeThis standard is applicable to cable cutting devices to be used to verify that a cable is dead inaccordance with the rules given in EN 50110.Cable cutting devices specified in this standard are for use on systems with nominal voltage up to30 kV AC and nominal frequencies up to 60 Hz.For devices to be used on systems with nominal voltages above 30 kV AC this standard should beused as a guide but additional requirements and tests shall be agreed between manufacturer andcustomer to provide for an equivalent level of safety.These devices are not designed to be used on cables with special armour, or with steel wires orsteel tapes more than 1 mm in diameter or thickness.2Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications.
