外觀Appearance
外觀不應(yīng)有顯著的污點、裂紋。
There shall not be any remarkable stain,rust or crack on the appearances.
標(biāo)示應(yīng)該很容易辨識。
Marking shall be easily legible.
機械特性Mechanical characteristics
拉力強度試驗Tensile test
將保險絲固定好后,對保險絲引線施加5N的拉力,持續(xù)1分鐘。試驗過后,保險絲沒有任何破損現(xiàn)象。
Exert the axial pulling force of 5N to the both ends of lead wire for 1 minute. After the test the fuse shall be no damage and loosening.
電氣特性Electrical characteristics
實驗條件Test condition
所有測試環(huán)境溫度為25±5℃。
All electrical characteristics tests are conducted at an ambient temperature of 25±5℃.

絲的絕緣阻抗值大于0.1ΜΩ。
The fuse interrupting capacity:35A or 10 times the rated current whichever is greater. After
interrupting, the insulation resistance between the fuse terminations shall be not less than 0.1ΜΩ.
3溫度上升試驗:通1.5倍額定電流15分鐘,然后每隔15分鐘增加0.1倍額定電流。測得保
險絲斷開時任何部位的溫升不得超過135℃,周圍環(huán)境溫度為25±5℃。
Temperature Rising Test: The rated current of 1.5 times is applied for 15 minutes. After the first
15minutes, the current is increased by 0.1 times the rated current every 15 minutes until the fuse
operates. The temperature rising on the fuse surface is not higher than 135℃.

耐久性測試 Endurance test
對保險絲通過相關(guān)標(biāo)準(zhǔn)規(guī)格單規(guī)定的額定電流1小時,然后截斷電流15分鐘,將該循環(huán)重復(fù)
100次。試驗過后保險絲沒有任何破損現(xiàn)象。
A ampere rating specified in the relevant standard sheet is passed through the fuse for a period of
1h.The current is then switched off for a period of 15 minutes. This cycle is repeated 100 times. After
the test the fuse shall be no damage and loosening.
