Compliance is checked by inspection, by measurement and by fitting cables or cords of the smallest and
largest cross-sectional areas specified.
Terminals for supply cord shall be suitable for their purpose.
Compliance is checked by inspection and by applying a pull of 5 N to the connection.
After the test, the connections shall show no damage which could impair compliance with this standard.
25.3 For tools with type X attachments, terminals shall be so fixed that, when the clamping means is
tightened or loosened, the terminal does not work loose, internal wiring is not subjected to stress, and
creepage distances and clearances are not reduced below the values specified in 28.1.
Compliance is checked by inspection, and by the test of 9.6 of IEC 60999-1, the torque applied being,
however, equal to two-thirds of the torque specified in Table IV of that standard.
Terminals may be prevented from working loose by fixing with two screws, by fixing with one screw in a
recess, so that there is no appreciable play, or by other suitable means.
The requirement for fixation of terminals does not preclude the provision of supply terminals on switches,
or similar device in a recess if, after connection of the supply cable, and after re-positioning of the switch
or similar device in its recess, it can be verified by inspection that these components and the supply cable
are, after re-assembly of the tool, in the correct position.
Covering with sealing compound without other means of locking is not considered to be sufficient.
Self-hardening resins may, however, be used to lock terminals which are not subject to torsion in normal
use.
