YY-500 Ceramic Crazing Tester

Introduction Of Instrument:

The instrument uses the principle of electric heater heating water to produce steam design, its performance in line with the national standard GB/T3810.11-2016 and ISO10545-11: 1994 “Ceramic tile enamel anti-cracking test method” requirements for test equipment, suitable for ceramic tile anti-cracking test, but also suitable for working pressure of 0-1.0MPa other pressure tests.

The samples are subjected to saturated steam at a defined pressure for a number of cycles in an autoclave to test resistance to crazing due to moisture expansion, The steam pressure is increased and reduced slowly in order to minimize thermal shock, The samples are examined for crazing after each cycle, A stain is applied to the surface toaid in the detection of crazing cracks.
