IEC60950-1-2001: clause 4.5.2
4.5.2 Resistance to abnormal heat
Thermoplastic parts on which parts at HAZARDOUS VOLTAGE are directly mounted shall be
resistant to abnormal heat.
Compliance is checked by subjecting the part to the ball pressure test according to
IEC 60695-10-2. The test is not made if it is clear from examination of the physical
characteristics of the material that it will meet the requirements of this test.
The test is made in a heating cabinet at a temperature of (T – Tamb + 40 °C) ± 2 °C (see 1.4.12.1
for the significance of T and Tamb). However, a thermoplastic part supporting parts in a PRIMARY
CIRCUIT is tested at a minimum of 125 °C.
