Whole Shoes Flexing Tester Test Method

2019-09-20

Footwear Testing Equipment For Shoes Flexing Tester
Whole Shoes Flexing Tester applies SATRA TM92 standard, is used to test the flexing resistance of finished shoes or shoe sole.

Test purposes:
Whole Shoes Flexing Tester is used to test finished shoes, like sports shoes, casual shoes, work shoes etc. And determine its flexibility resistance or indicating the cracks of shoe or shoe sole through reciprocating flexing movements under the specified angle and frequency. 

Test equipment:
Whole Shoes Flexing Tester GT-KA01-2

 

 

 

The shoe bending tester consists of the following structural components:
a) swinging the metal plate with a swing frequency of 140 times/min;
b) two artificial feet of adjustable size and position;
c) digital counter with reset function, which can be set by testing the required number of times of operation;
d) Angle adjustment device, adjustable to zero position (start position);
f) The control panel can switch the working state of the instrument and set the counter, including: start button, stop button, manual button, reset button, preset electronic counter.

 

Sample requirements:
The sample shall be the finished shoe after 48 hours of processing, with no obvious defects.Each group of samples is not less than two pairs.The sample shall be tested after a temperature adjustment of the test chamber for 6 hours.


Test conditions:
1. The bending angles are adjustable from 30°45°, 50°, 60°, 90°, etc.
2. The test speed is 50 to 150 times/min.
3. Laboratory temperature: 23 ± 2 ° C.


Experiment Procedure:
1. Adjust the eccentricity of the test machine so that the bending angle reaches a specified angle.
2. Place the sample shoe on the test machine.
3. Adjust the distance of the clamp in the shoe so that the front end of the clamp is at the toe of the shoe.
4. Zero the counter before the test starts, set the number of bends to the specified value, and start the host to start the test.
5. After the specified number of tests is reached, observe the changes after the whole shoe is bent.

 


Testing Report:
The bending value is expressed in number of times, no crack is acceptable, the crack is unqualified, and the length of the crack is expressed in millimeters. The test results of each pair of shoes are subject to visual inspection. If one of them has only a crack, the pair of shoes are treated as cracks.
