ASTM C 368 Pendulum Impact Testing Machine Ceramics Impact Tester
ASTM C 368 Pendulum Impact Testing Machine Ceramics Lmpact Tester
1.Description:
Description:
This daily-use ceramic impact testing instrument is used for impact tests on the centers of flat tableware and concave vessels, as well as impact tests on the edges of concave vessels. The impact test on the edge of flat tableware involves either glazed or unglazed samples. The impact test at the center of the vessel is used to measure: 1. The energy of the initial strike that causes the initial crack. 2. The energy required for complete breakage.
2.Standard:
GB/T 4742 - Method for Measuring Impact Toughness of Domestic Ceramics, QB/T 1993-2012 "Test Method for Impact Resistance of Ceramic Ware", and the American standard ASTM C 368 - Test Method for Impact Resistance of Ceramic Ware.
