Quality control
1:Fragment Strength Test
Testing standard:Chatillon model LTC
Load tester: displacement accuracy: 0.01 mm, and movable 1 mm, 0.1 mm, 0.01 mm
Force accuracy: 0.1gf (1kg capacity)
Testing head: 3.0 mm (0.12") flat head Ukrainian steel, x 2.5 times strength.
Height tester e: 0.001-600 mm, minimum unit 0.001 mm



2:Testing
The center of the metal shrapnel is located in the center of the test head of the load tester. The shrapnel must be aligned vertically with the test head, placed on a hard plane, and left a vent to ensure the accuracy of the test results. The excess air at the bottom of the shrapnel affects the strength and results in erroneous results.

3:Life test of shrapnel
The center of the metal shrapnel is located in the center of the test head of the load tester. The shrapnel must be aligned vertically with the test head, placed on a hard plane, and left a vent to ensure the accuracy of the test results. The life test of progress shrapnel at room temperature.
The test speed range is: 1-10 times per second; counter: 6 bits (1 million times), counting once per time;
