30.1 External parts of non-metallic material, parts of insulating material supporting live parts including connections, and parts of thermoplastic material providing supplementary insulation or reinforced insulation, shall be sufficiently resistant to heat if their deterioration could cause the appliance to fail to comply with this standard. This requirement does not apply to the insulation or sheath of flexible cords or internal wiring.
Compliance is checked by subjecting the relevant part to the ball pressure test of IEC 60695-10-2. The test is carried out at a temperature of 40 °C ± 2 °C plus the maximum temperature rise determined during the test of clause 11, but it shall be at least – 75 °C ± 2 °C, for external parts; – 125 °C ± 2 °C, for parts supporting live parts.
标准明确规定支撑带电部件的材料(并没有说为热缩型材料不需要做)需要做球压测试.但是如果是提供附加绝缘或加加强绝缘才考滤热缩型材料,是热缩性材料才不做. |
