Enviormental Stress Cracking Apparatus

Cracking Resistance (ESCR) Apparatus determines the susceptibility of ethylene plastics to stress-cracking when exposed to different environments such as soaps, wetting agents, oils and detergents. When the material is under certain conditions of stress, these reagents can accelerate the cracking process which is one of the most common causes of unexpected brittle failure of polymers known. Designed in accordance with the ISO 4599, ASTM D1693 international test standard, the apparatus is extremely cost effective and very simple to use.

►  Manufactured to a high standard, the apparatus is supplied with electronic digital temperature control, temperature bath and all tooling accessories.

►  The integrated temperature bath fitted with digital temperature controller, heater and a PT100 platinum resistance thermometer accurately maintains the test temperature, accuracy is ± 0.5 °C.

►  To ensure temperature stability within the bath, a stirrer motor system is fitted and the built in electronic timer monitors the duration of the test. 

►  The bath is fitted with a stainless steel sample rack which holds up to 8 glass test tubes which are immersed in a heat transfer medium such as silicone oil.

►  The specimen holder is designed to maintain a constant stress on the mid section of the test samples with up to 8 specimens fitted into a specimen holder at one time.
