Protear Elmendorf Heavy Duty Tearing Tester
Microprocessor controlled tear tester with testing capacities up to 25,000g
Manufactured by Thwing Albert, the instrument is specifically designed for heavy duty substrates and equipped with pneumatic pendulum release, statistical analysis of results and with a choice of interchangeable pendulums.
The Elmendorf Tear Testers are essential in materials quality control, providing more information on tearing properties than any other instrument. They are recognised as the worldwide standard and are the best way to accurately measure the tear resistance of heavy duty sheet materials.
The tearing resistance of a material is measured via the transference of the potential energy stored in the raised pendulum to kinetic energy. A portion of this energy is absorbed during the tearing of the sample and is used as a measure of the material’s resistance to a continuing tear. The force required to tear the sample is reported as a percentage of the pendulum capacity.
The heavy duty tester offers capacity configurations ranging from standard 6,400g increasing to 25,000g. Capacities are changed quickly and easily by adding augmenting weights, a configuration that eliminates the necessity for multiple pendulums and simplifies the testing of different materials.
Standards: DIN 53862; DIN 53128; ISO 1974; ASTM D295; D751; D1424; D1922; TAPPI T-414; T-496; BS 4253; BS 4468; CPPA D.9; SCAN P-11
