4.1 负载容量：额定电流测100%，能继续通电*熔化现象。        
4.1 Loading Capacity The Listed Electrical.(Included) add 100%for following,and it's available to let        
    Current Kurrcnt Keep on flowinng without any melding        
4.2 温度特性：进行上项测试1.5  小时，后继续维持原加之电流，每隔十分钟测试一次，继续测试        
    三次，温度不得升高，若使用热偶式测量方法，（Thermometer method)则本体温度在70℃以下        
    若使用温度计测量方法（Thermometer method)则在50℃以下。        
4.2 Temperature proceed: the prccedingtest for1.5  hours,keep testing iteith 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℃ by way of Thermocouple Method While it keeps below        
    50℃ by way of Thermometer Mcthod.         
4.3 电阻测量：调整保险丝之额定电流值达10%时，在保险丝两端使用高阻*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）        
4.3 Resistance Measuring:Adjust the fuse upto 10% more than listde electrical current the 10%,we        
    mcasure on two ends of the fuse with high voltage meter,and caculare the resistance value with        
    elec-trical brige way.(If the listed currecct equal or more the 2.5  Amp,it's not necessary to        
    measure the resistance value.)

   无松动或损坏现象发生。        
5.1Leads and/or caps are soldcred(adhcred)to withstand axial pulling force 1.1 pounds 5         
   min without loosening ou any harfulness to firmly arlachment        
5.2 回转强试Torsion Strength:        
   1 固定一端铜头，另一端施加 720 g/cm 的力左右摇动，铜头不得拉动及发生任何本体损坏        
          After being subjecteedd to 720 g/cm torsion go one cap while te othe terminal fixed,no any        
         damage or loo*ning resulted        
        
  2  一端导线弯折90度，本体以原轴旋转360度（五秒），三次不同方向旋转。导线或结合处不        
     发生损坏        
       One lead bent through90o,the body be clamped and rotated through 360o at a rate or 5 sec        
        about the original axis,Vophisical damage to leads or connections twsulted after 3 successive
