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/

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...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...

Comparative analysis of water-cooled and air-cooled xenon lamp aging tester

Xenon lamp aging test chamber is the core component of using the box full sunlight spectrum xenon lamp tube simulation, under different environmental conditions to simulate the material aging law, through the experimental results to evaluate weather resistance of materials and products. This paper focuses on the comparative analysis of the advantages and characteristics of the water-cooled and air-cooled xenon lamp aging testing machine. Air-cooled xenon lamp aging test machine : A circular wind is used to cool the heat-trapping xenon lamp tube. Air-cooled xenon lamp tubes used in air-cooled xenon lamp aging test box, generally a typhoon cold xenon lamp aging test chamber is equipped with three air-cooled xenon lamp tubes, and table 1 air-cooled xenon lamp weather-resistant chamber equipped with xenon lamp tubes. The power of the air-cooled xenon lamp tube is generally 1.8kw, and the length of the lamp tube is 340mm compared with that of the water-cooled xenon lamp. The diameter of...
