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
