 Notched Constant Tensile Load Tester,which also named Environmental Stress Cracking Tester or ASTM D5397-99 Enviromental Stress-cracking Tester.It is used to determine the environmental stress cracking ability of ethylene – based tree ester and plastic. It is suitable for the original granule of cable sheath.

Notched Constant Tensile Load Tester DW1440

Notched Constant Tensile Load Tester is mainly used for stress cracking test of polyethylene plastics.

It includes a Nicking Jig, bending clamp, transfer tool, specimen holder, test tubes and stoppers and a constant-temperature batch. Customer need make a specific notch on each test pieces by using the nicking jig,bend notched test pieces on the bending clamp, transfer bent notched test pieces onto the specimen holder by the transfer tool, pour the reagent into test tubes and insert specimen holder with test pieces into the test tube so that test pieces are immerged in the reagent and then place test tubes with test pieces and reagent in it into the constant-temperature bath for a specific time

We provide reasonable price and high quality Environmental Stress Cracking Tester

Follows are features of Notched Constant Tensile Load Tester
