Model RTC-II Cord Bending FatigueTester
|
|
In the RTC-II Cord Bending Fatigue Tester, the cord samples are subjected to repeated bending at given load through 2 free rotating rollers simultaneously and repeatedly moving up and down.
For testing, select some samples to be tested at the same time: fix the samples to the clamp in order, then wrap the cord around the A and B rollers to be connected with the lower clamps (see the following figure for instruction). Then the test starts, the A and B rollers will repeatedly move up and down, and the cord is subjected to a repeated bending fatigue. Record the number of bending times before breaking of every cord, collect data from all cords, and round the results to the nearest number, which indicates the fatigue resistance of the sample. Alternatively, you can also measure the remaining strength of unbroken cord after certain amount of bending, and use this remaining strength as an indication of the fatigue resistance of the sample.
