10.耐久性试验/ ENDURANCE TEST
耐久性试验过程（The
process of endurance test is as follows.）
1）对熔断½通过 1
倍的额定电流
1
小时，然后切断电流
15
分钟，重复此循环
100
次。
current 1.0In is passed through the fuse-link for a period of 1hour. The current is then switched off for a period
of 15 minutes. The cycle is repeated 100 times.
2）然后对熔断½通以 1.5
倍额定电流
1
小时；并测量两端电压降，计算其最大功耗不½超过上表所规定的最大
值。
Fuse through to 1.5 times the rated current of 1 hour; and measure the voltage drop across, to calculate the
maximum power consumption can not exceed the above table under the maximum
3）测量熔断½两端的电压降,且电压降的增大量不大于试验前测得值 10%。
Measuring both ends of the fuse voltage drop, and a large number of the
increased voltage drop is not greater than 10% of the measured value
before the test.
4）
试验后,标记仍应清晰可辨，而且诸如端½上的焊点不应出现任½明显的劣变。
After the test, the marking shall still be legible and soldered joints on end caps, for example, shall not show
and appreciable deterioration.
