8.15 If compliance with this standard depends upon the operation of a replaceable thermal link or
fuse-link, the reference number or other means for identifying the link shall be marked on the link, or in a
place that it is clearly visible after the link has failed, when the tool has been dismantled to the extent
necessary for replacing the link.
This requirement does not apply to links which can only be replaced together with a part of the tool.
Compliance is checked by inspection.
9 Protection against access to live parts
Tools shall be so constructed and enclosed that there is adequate protection against accidental contact
with live parts.
Compliance is checked by inspection, and by the tests of 9.2 to 9.4, as applicable.
9.1 An accessible part is not considered to be live if:
– the part is supplied with safety extra-low voltage, provided that
• for a.c., the peak value of the voltage does not exceed 42 V;
• for d.c., the voltage does not exceed 42 V;
or
– the part is separated from live parts by protective impedance.
In the case of protective impedance, the current between the part and the supply source shall not exceed
2 mA for d.c., and its peak value shall not exceed 0,7 mA for a.c., and moreover:
– for voltages having a peak value over 42 V up to and including 450 V, the capacitance shall
not exceed 0,1 µF;
– for voltages having a peak value over 450 V up to and including 15 kV, the discharge shall
not exceed 45 µC.
Compliance is checked by operating the tool at rated voltage. Voltages and currents are measured
between the relevant parts and either pole of the supply source. Discharges are measured immediately
after the interruption of the supply.
