  • Inquiry

Introduction:

Plastic Environmental Stress-Cracking Tester聽 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.

Working Principle:

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.

Standard:

ASTM D1693聽

ISO 4599

Temperature rangeRT-95鈩
Temperature accuracy卤0.5鈩
Temperature fluctuation卤0.2鈩
Temperature gradient卤0.5鈩
Nicking depth0~1mm, adjustable
