Second, sponge constant load impact tester main scope and functions:
Mainly used for reciprocating impact compression foam polymeric material fatigue test, the determination of the thickness of the specimen to reduce value and lower hardness values (residual deformation rate), and thus can understand the dynamic fatigue properties of materials. The instrument at the same time satisfy the standard of our country auto industry QCT56-93 car seat liner material performance test methods and abroad such as Japan's auto industry standard JASOB408-84 standard requirements. This instrument adopts the microprocessor control, automatic setting load load size and number of reciprocating compressor, when the load is less than or greater than the setting load can automatically adjust, in a set of numerical test is carried out under load. LCD screen display Chinese operations, this instrument is to use easy to operate, reliable performance, high measurement precision, etc.
