I. Instruments summary:

Used for impact test of flat tableware and concave ware center and impact test of

concave ware edge. Flat tableware edge crushing test, the sample can be glazed or not

glazed. The impact test on the test center is used to measure: 1. The energy of a blow

that produces the initial crack. 2. Produce the energy needed for complete crushing.
