4.1玻璃管Gl tube（陶瓷管Cermic tube） 玻璃管或陶瓷管须陷、缺损、凹陷，明显脏污。（The gl tube should be of no blemish, no damage and no pollution.） 4.2铜帽（Copper cap） 每个铜帽须焊接牢固，导电性良好，表面镀层结合牢固，不易脱落，伤。浸入温度为15-35℃的水中24小时，按标准的要求施加轴向拉力5N，并持续1分钟，不会出现松动、松脱的情况。（Every copper cap must be welded tightly and have good electric conductivity. Also the outer coating can be very tight, and not easily fallen off. It can be immersed in water with temperature between 15-35℃for 24 hours. Every copper cap can stand axial pulling force 5N exercised by special equipment for minute.） 4.3焊锡（solder） 焊料应具有良好的电接触性能，并且在正常使用时不应有熔化的迹象。(The welding materials should have good electric conductivity and not be melted at normal using.) 4.4引线(Lead tail) 引线采用镀锡铜线，具有良好的可焊性能，导电性能。可焊性合GB2423.28-82 /IEC68-2-20之标准。引线的尺寸以及形状可以根据客户的不同要求制作。（Lead should be tinned and have the performance of welding and good contact with electricity.Jionting performance apply for GB2423.28-82/IEC68-2-20 standard） 5.电气性能(Electricity function) 5.1测试具备的环境条件如下(The environment condition of the tt)：

5.4耐久性试验(Endurance tt) 对保险丝通过1.0In电流1小时，然后断电15分钟，此为一个循环，如此经过100次循环后，再对保险丝通以1.5In持续1小时，此测试完成后，再量保险丝两端的电压降，此数值不出10%的变化。并且相关数据不能出规格表中的要求。同时在测试过程中不能出现保险丝断开的情况。 Fuse shall carry 100% of rated current continuously for1 hour.Immediately after,The current is switched off for 15 minut. This cycle is repeated 100 tim. After 100 cycl, Fuse shallcarry 150% of rated currend continuously for1 hour.Immediately after,Fuse shall carry 100% of rated currendin order to measurethe fuse voltage drop. the voltage drop shall not be deviated from the value before endurance tt by more than 10% and the value can not exceed the standard list. Meanwhile, the fuse can not open during the above tts. 规格表
