The Elmendorf Tear Tester is an automated tear tester equipped with an optical encoder for measuring the angular position of the pendulum during .
One use of these results would be for the specification of material and thickness for plastic film used in packaging. Depending upon the application, a low propagation force or a high propagation force might be more desirable. . There are 3 standard samples for Elmendorf Tear testing. The preferred test sample for plastic films is the .Tear resistance is one of the properties that make a plastic film strong. It proves to be crucial for its durability if the material is subjected to tear events. When testing a film's tensile strength, tensile modulus and tear resistance are often used in conjunction to provide a comprehensive picture of its strength. ASTM D1004 Test MethodElmendorf Tear Strength Tester is used to test how well the material can withstand the effect of tearing. The elmendorf tear tester is suitable to test textile, non-woven fabric, plastic film, paper and etc. Elmendorf tear strength tester test methods includes ASTM D1922, ASTM D1424, DIN 53862, EN ISO 13937-1, ISO 4674-2 and etc. Welcome to .Work with us to find the right equipment for your ASTM standard ASTM D5587 | Textiles | Tension Testing ASTM D5587 is a testing specification that determines the tearing strength of textile fabrics by the trapezoid procedure using a recording constant-rate-of-extension-type (CRE) tensile testing machine. This test method applies to most fabrics such as woven fabrics,

Physical specifications: 584 x 483 x 406 mm; Net weight 16.8 kg .
5.1 This test method is of value in rating the tear-propagation resistance of various plastic films and thin sheeting of comparable thickness. For highly extensible film or sheeting the deformation energy of the specimen legs is significantly greater than the tearing energy. The tear-propagation resistance in slightly extensible or non-extensible film or sheeting is .

The drop weight tear test (DWTT), specified in API RP 5L3 or ASTM E436, was developed in the early 1960s at the Battelle Memorial Institute, USA, to overcome some limitations of the 'Pellini' drop-weight test. Drop weight tear testing is a material characterisation test aimed at avoiding brittle fracture and ensuring crack arrest in pipelines (seamless or welded).cause a nick or cut in a Type A (nicked crescent) test piece to grow by tearing the rubber, divided by the thickness of the test piece. 3.2.2 Type B tear strength—the maximum force required to cause a nick or cut in a Type B (nicked tab end) test piece to grow by tearing the rubber, divided by the thickness of the test piece.S; Tear length: 43mm;Specifications subject to change without notice.

ABB’s L&W Tearing Tester uses the tearing principle according to the Elmendorf method, which is the classical method to measure tearing resistance in paper. The instrument now offers several enhanced features for automatic, easy and safe operation to get more tests done – faster. Features • Intuitive touchscreen with user-friendly interface One way to measure tear resistance is through the Pendulum Method or Elmendorf Tear Test, as defined by ASTM D1922. . The resulting data can be used to determine the material and thickness specifications for plastic film used in packaging. To perform the test, ten samples each are cut from the plastic film in the machine direction and in the .Smithers also measures tear initiation using a Finch tear attachment on a tensile test machine. This edge tear test conforms to Tappi T470. Standards and accreditation. There are many applicable standards including BS EN 21974, ISO 1974, Tappi T414,DIN 53128, and SCAN P11. Smithers is UKAS, ISO 17025 accredited for the determination of internal . apex. If tear initiation does not occur at the apex, the results are more indicative of tensile strength than tear strength. 4.2.4 Type T, a trouser tear test piece, as shown in Fig. 2 .
