4.5 out of 5 based on 6 customer ratings
(6 customer reviews)

Elmendorf Tear tester, a computer controlled falling-pendulum instrument, to decide the ballistic tearing strength of textiles, plastics, paper or board. Tear Strength Tester complies with ASTM D1424/5734, ISO 1974/9290, BS ISO 13937, etc. The tearing tester is further enhanced and supported by the easy to use computer. Elmendorf Tear Strength Tester will show its good performance when you do Elmendorf tear test.


Auto Elmendorf Tear Tester (patented product), is used to determine the ballistic tearing strength of textiles, plastics, paper or board.

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.

Elmendorf type tear tester is not applied to sparse fabric or stretch materials which the tearing direction might be shift in test.

Compressed air of 0.4~ 0.7 mPa is required.


  • Works in accordance with all known test standards.
  • The model is the only one that covers the most completed test range from 0 to 12800cN.

Some information about tear strength tester you may need to know:

  1. What are the relevant standards of domestic and foreign textile tearing strength testing?

    at present, the most commonly used method of fabric tearing strength test is mainly the pendulum method, tongue method and trapezoidal method. Aside from these three methods, there is also Wing method, rectangle method and nail method used nationally. Table 1 shows the relevant standards for testing the tearing strength of textiles.

  2. What are the test methods of the tearing strength? What are the characteristics of each of them?

    Breaking strength is also known as tearing strength. The testing methods includes trapezoidal method, tongue method (there is a single tongue and double tongue of the points), hammer fall method. Strictly speaking, hammer fall method also belongs to the tongue method, but the ways of determination are different.

    trapezoidal method: Draw two diagonal lines at the ends of the strip to form an isosceles triangle in the middle and then cut at the bottom. Try to clamp and follow the two diagonal lines and add tensile loading. The first yarn that is close to the incision will bear more external force, while the other yarns will endure less force. When the first yarn experience cracks, it will split. Then the line below will become the first yarn. It will endure strong tension until tears apart.

    tongue method: Cut it into two pieces along the length of the strip. Apply tensile load in the two clamps of the machine respectively. The yarn in longitudinal direction experiences tension; the lateral yarn slides. The tension of the sliding yarn and the elongation increases dramatically and will form a stressed triangle. The first yarn of the bottom incision of the triangle withstands the greatest force. When it tears, it will have the highest tear value. The yarn breaks one by one until the fabric is torn. Factors affecting the triangle will also affect the fabric tearing strength. So, that is why  the strength of tongue tear does not only reflect the tenacity of the fabric, it can also evaluate the effect of dyeing and finishing process and other factors caused by the friction effect of tear on the impact. The result of a single tongue tear is generally expressed as the maximum value during tearing. When a more accurate result is needed, it is available as the mean value of the five peaks. However, at this point, the five zone markings must be made starting at 5 mm from the incision (12.5 mm length for each zone) within the tear length on the specimen. During testing, when it is torn to a marking, put a marking to a corresponding point in the recording curve. Afterwards, read the highest value in each of the region, and take the average. Note: the zone division must be made on the sample otherwise it cannot be determined in the curve because the displacement of the curve includes the length of tearing, as well as the slip of yarn and elongation.

    Hammer fall method: The testing method uses the principle of conversation of energy, which measures the energy consumed to test the tearing of a specific length of fabric. (Fall of Fan-shaped pendulum and potential energy consumed). The energy will be converted into the strength of tearing, which is the average tearing  strength of the process of tearing. The feature of Hammer fall method and tongue method are similar. They quickly complete the tearing process. It is easy to use. The result is stable and is popular nationally.
