ART-ESCR Environmental Stress Cracking Apparatus

Benefits

• Simple stress cracking determination for Ethylene Plastics.
• Designed in accordance with the ASTM D1693 international test standard.
• Integrated stirrer motor ensures absolute temperature stability throughout the bath.
• Electronic timer monitors the total test duration.
• 316 stainless steel rack accommodates up to 46 borosilicate test tubes submerged in a heat transfer medium.
• Each tube is supplied with a rubber stopper and a brass specimen holder designed to maintain constant stress on the mid-section of the test samples.
• Each specimen holder can house up to 10 specimens simultaneously.
• For operator safety, the unit is fitted with a secondary thermostat, an emergency stop, and a protective bath lid.
• Full traceable certificate of calibration and instrument user manual.
• UKCA/CE certified.

To compliment the Environmental Stress Cracking Apparatus (ESCA), a full set of tooling is supplied to prepare the sample ready for test. This includes, sample cutting die (38mm x 13mm), sample bending clamp, a sample nicking jig  to initiate controlled stress points. and sample transfer tool for secure specimen management.

How does the ESCA perform environmental stress cracking testing?

The ESCA measures environmental stress cracking resistance by simulating conditions where soaps, wetting agents, oils, or detergents accelerate mechanical failure, allowing for the identification of potential ruptures caused by tensile stresses significantly lower than a material’s short-time mechanical strength.
