IEC60335-2-79 撞击试验装置是广东安规检测有限公司根据标准IEC60335-2-79第22.35及图102设计制造而成。
IEC60335-2-79标准要求:
22.35 Modification:
These parts are subject to the hammer test of Clause 21. If this insulation does not meet the requirement of 29.3, these are subject to the following impact test.
A sample of the covered part is conditioned at a temperature of 70 ºC ± 2 ºC for 7 days (168 h). After conditioning, the sample is allowed to attain approximately room temperature.
Inspection shall show that the covering has not shrunk to such an extent that the required insulation is no longer given or that the covering has not peeled off, so that it may move longitudinally.
After this, the sample is maintained for 4 h at a temperature of – 10 ºC ± 2 ºC.
While still at this temperature, the sample is then subjected to impact by means of the
apparatus shown in Figure 102. The weight "A", having a mass of 0,3 kg, falls from a height of 350 mm onto the chisel "B" of hardened steel, the edge of which is placed on the sample.
One impact is applied to each place where the insulation is likely to be weak or damaged in normal use, the distance between the points of impact being at least 10 mm.
After this test, it shall show that the insulation has not peeled off and an electric strength test as specified in 16.3 is made between metal parts and metal foil wrapped round the insulation in the required area.
