ASTM D1922 Plastic Film and Thin Sheeting Pendulum Tear Resistance Tester SLY-S1 is designed for the tearing test of films, sheets, flexible PVC, PVDC, waterproof films, woven materials, polypropylene, polyester, paper, cardboard, textiles and non wovens. ASTM D1922 Plastic Film and Thin Sheeting Pendulum Tear Resistance Tester is the necessary testing instrument for the packaging,paper industries, quality inspections and quarantine labs. Standards:ISO 6383-1-1983, ISO 6383-2-1983, ISO 1974, ASTM D1922, ASTM D1424, ASTM D689, TAPPI T414 Test Principle Lift the pendulum up to a certain height to give it an initial potential energy. The pendulum tears the specimen while swinging down. Computer calculates the decreased energy caused by tearing to obtain the required force for tearing.
It is controlled by micro-computer, large LCD display It is designed by automatic and electronic measurement which improves the testing accuracy Pneumatic specimen clamping and automatic release of pendulum could avoid the system error effectively Computer assisted horizontal adjustment system could maintain the instrument optimum status ASTM D1922 Plastic Film and Thin Sheeting Pendulum Tear Resistance Tester is equipped with double system operation, micro-computer or computer software control Professional software supports multi-unit data output It is equipped with pendulums of multiple capacities mainframe, Professional Software, Communication Cable, One Basic Pendulum and One Extra Weight Optional Configurations: Basic Pendulum: 200 gf, 1600 gf Extra Weight: 400 gf, 800 gf, 3200 gf, 6400 g
