Product Name: Environmental Stress Crack Test Equipment for Plastic Model NO.: JJESC Trademark: JJ-TEST Transport Package: Wood Specification: ASTM D 1693 Origin: China HS Code: 90248000 Product Description It is used to determine the susceptibility of ethylene plastics, as defined in terminology D883, to environmental stress-cracking when subjected to the conditions specified in ASTM D1693-01. under certain conditions of stress and in the presence of environments such as soaps, wetting agents, oils, or detergents, ethylene plastics may exhibit mechanical failure by cracking.Bent specimens of the plastic, each having a controlled imperfection on one 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.
