The wire insulation coating inside motors deteriorates over time with typical wear and tear. Other factors that can cause a motor to fail prematurely include moisture or contamination of the insulation. . Insulation resistance testing with an instrument such as the Fluke 1555 FC 10 kV Insulation Tester with Fluke Connect® technology can .ASTM D1004 Tear Resistance This test method covers the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading, 51 mm (2 in.)/min. and is designed to measure the force to initiate tearing. The specimen geometry of this test method produces a stress concentration in a small areaThe mean force required to continue the tearing of an initial cut in a single sheet of paper is expressed as the internal tearing resistance. If the initial slit is made in the machine direction, the result is given as machine direction tearing resistance and similarly for the cross-machine direction (ISO 1974). Why measure tearing resistance?
The tearing strength tester is an appropriate tool to measure the tear resistance of various materials including textiles and fabric. Types of tear test: Tongue Test; Trapezoid; Elmendorf; Measurement of fabric tearing strength: Elmendorf tear tester: Sample Preparation: First we take specimen of 100 ×75 . Well, the force needed to tear the material is measured, and it offers a reliable indication of its tearing resistance. This materials test is suitable for a wide range of fabric types that contain woven, knitted and then non-woven materials.
