1. Test Objective
This machine is a special equipment for testing the bending fatigue strength of AC
and DC power cord. It can be automatic counting. When sample bending fold to
break causes no power, it can automatically stop operation. (standard type with
speed display)
1. Referring to standards
GB2099.1-2008< Household and Similar Use Plug Socket Part 1: General
Requirements> 23.4 soft cable and connecting requirements, as shown in figure 21
GB4706.1-2005<Household and Similar Use Household Appliance Part 1: General
Requirements>25.14 requirements, as shown in figure 8
GB/T5023.2-2008<Rated Voltage Equal to or Less Than 450/750 PVC Insulated
Cables Part 2: Test methods> Testing: Flexing Test, as shown in figure 2.Through
the conductor of electric current is about 0.1 A according to test requirement

2. Technical Parameters
 Fixture: 6 groups
 Power supply: AC220V ±10% 5A
 Motor power: 90W/220V AC
 Angle Bending: Left or right 30、45、60、90 adjustable(0°-180°adjustable
continuously)(Weights can be changed according to customer’s needs)
 Bending Speed: Can be directly display, Header display
 Counter: Six good parts counter, a preset counter
 Weight: 50g，100g，113g，200g，284g，300g，500g(select)
 Volume: 845×400×945MM
 Failure judgment: When there is a broken line to be measured, the
corresponding LED lights are not bright, the corresponding good counter to stop
counting.
 The show value is the times of bending about the tested power line. The
machine stops running when all lines to be measured are broken.
 Qualified judgment: When the test line is set to achieve the number of tests, the
detection device automatically stops, and shows good count.
