HY4150 enviromental stress-cracking tester

Descripción del producto

Application:
HY***0 Environmental Stress-Cracking Tester is used to determine the susceptibility of ethylene plastics to environmental stress-cracking when subjected to specified conditions and in the presence of environments such as soaps, wetting agents, oils, or detergents, ethylene plastic may exhibit mechanical failure by cracking. The principle is: Bent specimens of the plastic, each having a controlled imperfection on the surface, are exposed to the action of a surface-active agent. The proportion of the total number of specimens that crack in a given time is observed. 
This machine conforms to ISO ***9, ASTM D***3, GB/T ***2, etc.

Features:
1.It consists of constant-temperature bath, nicking jig, bending clamp, transfer tool, etc.
2.The constant-temperature bath can be independent test equipment to be used for conditioning test specimens
