applicable specification sheet (see 3.1).
3.5 Finished cords. The finished cords shall be in accordance with the requirements of this
specification and the applicable specification sheet (see 3.1).
3.6 Electrical requirements.
3.6.1 Dielectric withstanding voltage. The insulated conductors shall withstand, without breakdown,
an applied voltage of 500 volts DC (350 volts AC rms), when tested as specified in 4.6.2.1.
3.6.2 Insulation resistance. Immediately after the insulated conductors have been subjected to the
dielectric withstanding voltage test, the insulation resistance shall be measured as specified in 4.6.2.2.
The insulation resistance of each insulated conductor shall be not less than the value specified on the
applicable specification sheet (see 3.1).
3.6.3 Continuity. Each conductor of the finished cord shall be continuous when tested as specified in
4.6.2.3.
