The Operation Of Elmendorf Tearing Test

The Elmendorf Tearing Tester is a basic tear tester that offers an economic alternative to the electronic version. This model offers the quick change pendulum configuration without an electronic readout. Test results are obtained by means of a pointer on a graduated scale from 0-100%.


Digital Elmendorf Tearing Tester takes the Elmendorf method and is used to determinate tearing resistance property of films, sheets, flexible PVC, PVDC, waterproof films, woven materials, polypropylene, polyester, paper, cardboard, textile and non-woven, etc.Test range is 200-32000CN, while the impact force is corresponding to the specific pendulum. They determine ballistic tearing strength by propagating a single-rip tongue-type tear starting from a cut in a sample. The design is much user-friendly with wide range to meet different test and standards.



The operation of the Tear test is easy —simply secure the sample in the two 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 of the sample and is used as a measure of the materials resistance to a continuing tear. The energy required to tear the sample is reported as a percentage of the pendulum capacity or force.

    Thanks very much. Elmendorf tear tester enables rapid determination of the dynamic resistance of materials designed to be subject to strong shearing loads (e.g. fabrics) or liable to be damaged by sharp or heavy objects (e.g. paper bags). Subsequently, the test was naturally adopted for all materials in the form of sheet or films, cardboards, cloth, knitted fabrics, plastic films, aluminium foil, non-woven fabrics, complex flexible packaging etc. If you want to know Elmendorf tear tester price, please contact us: https://www.testextextile.com/product/elmendorf-tear-tester-tf140c/

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...

Synthetic Blood Penetration Tester for Medical Face Mask

  Features of Synthetic Blood Penetration Tester: 1. Mask fixture is metal human head mold, which can fully simulate the actual use state of the mask. 2. Metal human head mold can be rotated at a certain angle, which is convenient for sample clamping. 3. Specially designed injection control device, a certain volume of synthetic blood can be sprayed in the controlled time. 4. Instrument uses a gas source that can provide (700±25) kPa stable air pressure. 5. It can simulate the liquid injection velocity corresponding to the human blood pressure 10.6 kPa、16.0kPa 、21.3kPa (i.e .80 mmHg、120mmHg、160mmHg) for the test. 6. A fixed target plate is provided to block the high pressure edge part of the ejected liquid flow, only the steady flow part is sprayed on the area sample, which increases the accuracy and repeatability of the test. 7. This blood penetration testing equipment uses imported special aluminum wire drawing panel, equipped with metal keys, sensitive operation, not easy to dama...

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...
