3.2 两端铜盖:须以导电良好之黄铜底材料.
3.2 Tow brass and caps:Made of brass of good conductiviry.
   
3.3 铜盖处理:铜盖部分镀镍 标示最后若加"S"者表示须镀银
3.3Coating of brass caps plaring the surfacc with nickel If the indicaron is added with "S".
   it needs to be plared with silver.
   
3.4铜盖强度:铜盖和玻管本体间的扭力最小720g/cm.
3.4Slrength of brass caps:The minimum tortion beteen brass caps and glass tube is 720g/cm.
 
4  电气特性:(Charactcrristics of Electrical Appliancos)
4.1负载容量:额定电流测100%,能继续通电无任何熔化现象.
4.1 Loading Capacity :The listed electrical (Included) add 100% for following,add it's 
    available to let current kurrcnt.Keep on flowing without any  melding.
 
4.2温度特性:进行上项测试须1.5小时后继续维持原加之电流,每隔十分钟测试一次,连续测三次,温度不得
   升高,若使用热偶式测量方法(Tbermocouple  mcthod)则本体温升在70°C以下,若使用温度计测量方法
   则在 50°C以下.
4.2Temperature:Proceed the prcceding test for 1.5 houres ,Keep testing it with the original 
   current every 10 minutes.Continue to test it for 3 times The temperature is not allowed to
   be higher The main temperature is below 70°C by way of Thermocouple Method While it keeps
   below 50°C by way of Thermometer Mcthod.
 
4.3电阻测量:调整保险丝之额定电流达10%时,在保险丝两端使用高阻抗电压表测量降压值,以计算电阻值或
   电桥方式测量(额定电流2.5安培含以上者,无须测量电阻值)
4.3Resistance Measuring:Adjust the fuse upto  listed electrical current 10%,we measure on two
   ends of the fuse with high voltage meter and caculare the resistance value with electrical
   brige way.(If the listed currecct equal or more the 2.5 Amp,it's not necessary to measure 
   the resistance value)

5. 机械特性(Mechanical Properties):
   乃经下述实验证明(Terminal Connections & Lead Solderability)
 
5.1 拉力强度(Terminal Strength)
   当施加轴向拉力__1.1____磅于两端导线(或套盖)___5___分钟后,无松动或损坏现象发生.
   Lead and/or caps are soldcred(adhcrcd) to with stand axial pulling force of__1.1___pounds 
   for___5___mine.without loosening or any harmfulness to firmly arlachment.
 
5.2 回转强度(Torsion Strength)
    ① 固定一端铜头,另一端施加 720 g/cm 的力左右摇动,铜头不得松动及发生任何本体的损坏.
    After being subjecteed to  720 g/cm torsion to one cap while other terminal fixed ,no any 
    damage or loosmning resulted.
 
②一端导线弯折90度,本体以原轴旋转360度(5秒),三次不同方向之旋转后,导线或结合处不发生损坏.
   One lead bent through 90°the bady be clamped and rotated through 360°at a rate or(5 sec)
   about the original axis,Vophisical damage to leads or connections resulted after 3 time
   successive-altematero-tations.
 
5.3 弯折强度(Bending Strength):
   导线经过两次反方向之弯折后(弯折90度同折回原位置之一次弯折)不发生损坏.
   After two bends of Opposite directions(bending through an angle of 90°and back is detined
   as one bond ) of lead ,Nodamage are to be visualized.
