Edge tearing strength of paper is the load required to tear a sample over a V-notch fixture.Three standard methods are available for determining tear resistance of plastic films: ASTM D-1004 details a method for determining tear resistance at low rates of loading; a test in ASTM D-1922 measures the force required to propagate a precut slit across a sheet specimen; and ASTM D-1038 gives a method for determining tear propagation .
The size of the specimen and related fixtures requires the use of a dual column system, while the tensile and tear resistance tests can be performed on either a dual column or a single column system, such as Instron's 68SC-5 model. A 5kN or 10kN (1125 or 2250 lbf) system is the most common, capable of applying the vast majority of compressive . Fabric tear test is mainly used to test the tear resistance of film, sheet, soft polyvinyl chloride, textiles and non-wovens,etc. skip to Main Content +86-551-68 105003 [email protected] . Comprehensive and constantly-updated products, covering solutions to wide range demands of different materials, properties and test methods.The tear resistance is measured as the average force in mN propagating the tear to the edge of the test piece. We are UKAS accredited for testing to British standard BS 2782:3 method 360A. Smithers also test to International standard ISO 6383-2 and ASTM D1922.
It is a quantitative tear resistance test for plastic films, sheets, and materials in grams or millinewtons. Such results help manufacturers detect weak spots in the material and improve product durability by optimizing the manufacturing process. . The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions .Purpose of a tear test: The overall goal of a tear test is to determine a materials ability to resist the growth of the initial tear or its “tear resistance”. The value of a material’s tear resistance is generally accepted to be the force required to complete the tear so that it has gone completely though the material so that it has been .Tear resistance testing measures the force required to tear a polymerr test piece, from as small as a prepared cut or nick to a tear force completely across the width of a plastic or rubber material. For rubber materials, our rubber testing labs are equipped for all three of the trouser, crescent, and angle tear testing techniques.Originally introduced in 1964, ASTM D2261 was most recently updated in 2013 and specifies the method for tear testing of fabrics by the tongue (single rip) procedure to measure the tearing strength of the fabric.

Testing with the ProTear is easy - simply secure the sample in the clamps, make an initial tear with the attached blade and release the pendulum. The tearing resistance of the 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 ofThe tensile strength of a material is the maximum mechanical tension it can withstand before it cracks. It is given in N/mm² or MPa. The tear resistance of a material, also called tensile strength at break, is the mechanical tensile stress at the exact moment of tearing and is also given in N/mm² or MPa.. Since the maximum tensile stress and the tensile stress at the moment of .
