适用范围：1.1 This European Standard is applicable to the erection and operation of fixed and temporaryelectrical test installations.1.2 Compliance with this European Standard is not necessary, if contact with live parts presents nodanger. This is the case when one of the following conditions is satisfied at live exposed points:a) the voltage at frequencies above 500 Hz does not exceed 25 V a.c. or 60 V d.c. and complies withthe requirements for SELV or for PELV in accordance with HD 60364-4-41;b) in case of voltages at frequencies up to 500 Hz exceeding 25 V a.c. or 60 V d.c., the resultantcurrent through a non-inductive resistance of 2 kΩ does not exceed 3 mA a.c. (r.m.s.) or12 mA d.c;c) at frequencies above 500 Hz the national determined current and voltage values shall be applied.If there are no national requirements determined reference values for permissible body currentsand contact voltages can be taken from Table A.1;d) the discharge energy does not exceed 350 mJ.NOTE 1 Even though compliance with the requirements of this European Standard is not necessary, if one of the abovementionedconditions is satisfied, other potential risks e. g. risk of fire and explosion shall be considered and appropriatemeasures be taken.NOTE 2 Ref. 1.2 b) & 1.2 d): The values for the resultant current of 3 mA a.c. or 12 mA d.c. and the discharge energy of350 mJ comply with the values for live working specified in EN 50110-1. These values also comply with the values specified inIEC/TS 60479-1.1.3 This European Standard does not apply to the power supply to the test installations. In thiscase, the documents of the HD 60364 series (for nominal voltages up to 1 000 V) or HD 637 (fornominal voltages exceeding 1 kV) are applicable to erection and EN 50110-1 is applicable to operation.1.4 Where no requirements are given in this European Standard, the documents of theHD 60364 series (for nominal voltages up to 1 000 V) or HD 637 (for nominal voltages exceeding 1 kV)apply to the erection of electrical test installations and EN 50110-1 applies to the operation of electricaltest installations.
