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 D1424/1922/5734, ISO 1974/9290/6383-2, 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 (protear) 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.

What Factors to Pay Attention to when Determining the Tearing Strength?

1.The sample should be cut according to the size in the following chart.

ProjectTrapezoid MethodSingle Tongue MethodHammer Drop Method
Sample Length(mm)≥200 (approximately 150)≥20075 (approximately 63)
Sample Width(mm)50(After repairing the edge yarn)75100
Cut Length(mm)108020
Tear Length(mm)107513
Holding Distance(mm)10075<2
Stretching Rate(mm)200200(Hair Length 50)Hammer Drop

2. The test direction refers to the direction in which the yarn is torn, ie, the direction perpendicular to the incision, such as the warp yarns of the warp sample in the single tongue tear in the width direction, and the trapezoid method in the opposite direction.

3.The cut should be cut along the warp or weft direction, otherwise the tear may deviate from the cut during tearing.

4.When the specimen is clamped, the yarn at the incision can not be stressed.

5. Measurement observed in the observation of the tear of the specimen, such as the slit deviate from the incision extension line should be examined further. It should be removed and added to the results.

6.Drop the weight of the bezel in order to determine the pressure, full, not with the fan hem friction.


Elmendorf Tear Test – Pendulum Method

What is elmendorf tear definition? Elmendorf tear strength (or tear resistance) is a measure of how well a material can withstand the effects of tearing by pendulum method. Elmendorf tear tester manual and Elmendorf tear test units are most common used machines in this method.

The pendulum method (elmendorf test) is similar to the tongue tearing method and is in the family of fast tear strength test methods. The elmendorf tear test is commonly used. It can bet used for woven fabrics and also other fabrics that are produced with similar technology. However, this method can not be used for woven elastic fabrics, knitted fabrics, or any fabric that has the possibility of tearing transfer and has a great difference on weft and warp.

The Pendulum Method’s testing parameters have different national testing standards, as shown in Table 1 below.

Current GB / T 3917.1-2009 steps (elmendorf tear test procedure) for detection methods are as follows:

  1. Sample Preparation

Two sets of specimens were cut at a distance of 150 mm from the edge of the cloth, one for the warp sample and the other for the weft sample. The short side of the specimen shall be parallel to warp or weft to ensure that the tear is made along the incision. At least five samples of each group, the sample size shown in Figure 1. Tear length remains (43 ± 0.5) mm.


Fig: Sample Size

Fig: Sample Size / mm


Be careful when sampling, the sample should be representative to ensure that the sample does not contain the same between the warp and weft. Take the longitudinal direction of the sample, the sample should be parallel to the short side of the weft, not cut off incision weft; weft to take the same principle of the sample. After the sample is cut, put into a constant temperature and humidity laboratory humidity conditioning treatment before testing.

  1. Instrument Preparation

Check the calibration equipment, choose the quality of the pendulum, so that the elmenforf tear  test results of the sample fell within the range of 15% ~ 85% of the corresponding scale; with the calibration instrument at zero, the pendulum should rise to the starting position, the pointer is also placed at the zero position.

  1. Clamping the Specimen

The sample is sandwiched between the clamps so that the long side of the sample is centered, the lower side abuts against the base of the clamp head, the upper side is parallel to the top of the clamp head, and the two clamps clamp the sample evenly. In the middle of the opposite side of the groove of the sample, cut a (20 ± 0.5) mm incision with a shearing device according to the rule, leaving a length of (43 ± 0.5) mm to be torn.

  1. Measurement Performance

Start the instrument and let go of the pendulum for tearing. Hold the pendulum when it is in the high position, so as not to damage the position of the pointer, read out the data indicated by the pointer. The test results fall within the range of 15% ~ 85% of the scale used. According to the observations in the longitudinal and latitudinal directions, the mean (N) tear strength of the samples in the warp and weft directions are each calculated.

When testing, care should be taken to see if the tear is in the direction of the force, and whether the yarn slips off the fabric instead of being torn. If the fabric does not slip from the jaws, tear has been in the 15mm wide groove area, the test is normal, otherwise the results need to be removed. This method does not apply if three or more of the five specimens are rejected.
