4.9.2 Insulated linings, sleeves and similar parts shall have adequate mechanical, electrical
and thermal strength.
Compliance is checked by inspection, by manual test and by the electric strength test in
accordance with section 10. The thermal properties of wire and sleeve are checked in
accordance with section 12. Heat resistant sleeves used as covering for wires attaining a
temperature exceeding the values given in Table 12.2 of section 12 shall comply with the
requirements of IEC 60684, taking into account the temperature measured on the wire in
question. The sleeve shall be resistant to a temperature exceeding the temperature
measured on the wire by 20 °C or withstand the following test:
a) Three test specimens of the sleeve, about 15 cm in length, are subjected to the humidity
test of 9.3 and subsequently to the insulation resistance and electric strength tests
according to section 10. A suitable uninsulated copper conductor or metal rod is passed
through the specimens, and the outside is covered by a metal foil in such a way that no
flashover at the ends of the samples can occur. The measurement of the insulation
resistance and the electric strength test is then made between the copper
conductor/metal rod and the metal foil.
b) After the copper conductors/metal rods and metal foils have been removed, the
specimens are placed in a heating cabinet for 240 h at a temperature of T + 20 °C,
T being the measured temperature of the wire.
c) The specimens are allowed to cool to room temperature and are then prepared as
indicated under item a) above.
Measurement of the insulation resistance and electric strength is then made between the
copper conductor/metal rod and the metal foil.
Compliance is checked by the insulation resistance values and test voltages specified in
Tables 10.1 and 10.2 in section 10.
问：是否只要套管的耐热温度高于电线实测温度20 °C，就不需要做电气强度测试。还是任何套管都要经过相应的电气强度测试，以满足Insulated linings, sleeves and similar parts shall have adequate mechanical, electrical，and thermal strength.作者: ksxtye 时间: 2012-1-18 17:15
"The sleeve shall be resistant to a temperature exceeding the temperature measured on the wire by 20 °C or withstand the following test:"
根据这段文字的理解就是只要套管的耐热温度高于电线实测温度20 °C，就不需要做a) b) c)测试。作者: ll123456 时间: 2012-1-18 17:15
感谢楼上的回复，我想问的是，如果套管的耐热温度高于电线实测温度20 °C，是否需要根据第十章做电气强度测试（绝缘电阻和高压测试）。按字面意思说下面 a) b) c)所列的测试都是针对Thermal Strength 所需要做的，并未提及针对Electrical Strength的测试。作者: qing1234 时间: 2012-1-18 17:15
套管的耐热温度高于电线实测温度20 °C，前面还有一个前提条件的作者: jqtimo 时间: 2012-1-18 17:16
问：EN60598-1:2004 条款4.14.1中Test A,Test B,TestC具体是指那种类型的灯具，请指点！
