UL62-2006的条款:
5.2.3 Insulation resistance
5.2.3.1 Insulation resistance for all ²W² Type cords at 15°C
The insulation resistance of the insulated conductors shall be not less than shown in Table 47 or 48 when
a specimen of at least 15 m (50 ft) of the finished cord is tested in water at 15 °C immediately following
the dielectric strength test described in Clause 5.2.2. If tested at temperatures different than 15 °C, the
values shall be corrected to 15 °C.
5.2.3.2 Insulation resistance for all indoor cords at room temperature
The insulation resistance of the insulated conductors shall be not less than 0.76 GΩ?m (2.5 MΩ?1000 ft)
at 15 °C when a specimen of the finished cord at least 15 m (50 ft) in length is tested in air at 15 °C or
higher after conditioning for at least 6 h and immediately following the dielectric strength test described in
Clause 5.2.2.
5.2.3.3 Test method
Compliance with all insulation resistance tests shall be determined in accordance with the method
described in CSA C22.2 No. 0.3, Clause 4.28.2.1 and Table 15; UL 1581, Section 920; or
NMX-J-294-ANCE.
