3.2 陶瓷管 Ceramic Tube
陶瓷管无破裂、缺损或污染等现象。
Ceramic tube shall have no defects such as crack, injury and contamination.
4．电气特性 ELECTRICAL PERFORMANCES
4.1 测试条件 TEST CONDITIONS
全部测试条件都应在环境温度 20℃±5℃条件下进行。
All electrical tests are conducted at a ambient temperature of 20±5℃.
4.2 负载能力测试 CURRENT-CARRYING CAPACITY TEST
当熔断体通以100%倍额定电流的条件下进行测试时，在4小时内电路不应断开，熔断体不被电流熔断，管体不破裂。
A fuse-link shall carry 100% of rated current for 4 hours, and the circuit shall not be opened. While the fuse is
carrying this current, no open circuit, melt fusible element, and ruptured tube shall occur in any manner during this
test.
