Take the specimens to be used for the d221 of the crossmachine direction with the longer dimension parallel to the machine direction. Description Literature Contact Us Originally introduced inthe latest version was released in When testing to this standard, it is important to consider data rate.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Perform the test within 2 min after removal of the specimen from the water.

Preparation of Test Apparatus and Calibration 8. By continuing to use our site, you accept our cookie policy. The average results from the two laboratories should be compared using the appropriate statistical analysis and an acceptable probability level chosen by the two parties before testing is begun.

ASTM D2261 Tearing Strength of Fabrics

Take the specimens to be used for the measurement of machine direction with the longer dimension parallel to dd2261 cross-machine direction.

Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. This test method allows the use of the CRT-type tensile machine when agreed upon between the purchaser and the supplier. Current edition approved Feb. Typically for woven fabrics, if a small decrease in d226 occurs at a time when the force is increasing, it is not considered to peak unless the indicated force exceeds the force required to break a yarn.

Consequently, these test instruments d221 be used when agreed upon between the purchaser and the supplier. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

Tear Strength of Fabrics – Tongue Tear (Single Rip)

Strong fabrics or fabrics made from glass? As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of fabric of the type in question.

As the test is run, the jaws move apart and the fabric tears along the pre-cut segment. The three fabric types were: Precision and Bias Competent statistical assistance is recommended for the investigation of bias. Make a preliminary cut 75 mm 3 in. In this test method, a cut is made in a rectangular specimen, which starts a tear.

If any of the preceding modi? NOTE 2—The tabulated values of the critical differences should be considered to be a general statement, particularly with respect to betweenlaboratory precision.

When specimens are aztm be tested wet, take the specimens from areas adjacent to the dry test specimens. Originally introduced inthe latest version was released in Glossary of Materials Testing Terms.

Stop the crosshead motion after a total tear of approximately 75 mm 3 in. Email addresses must contain the symbol. Instructions are provided for testing specimens with or without wetting.

ASTM D Tearing Strength of Textile Fabrics – Instron

In spite of the empirical nature of the reported values, the values are considered to reflect comparative performance of similar fabrics tested and measured in the same way.

Referenced Asgm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Onsite Training At Your Facility. Record values as read from the direct-reading scale to the nearest 0. The tearing force may increase to a simple maximum value, or may show several maxima and minima, as shown in Fig. Larger differences are likely to occur under all other circumstances. Email addresses can only contain letters, numbers and the following special characters: Link to Active This link will always route to the current Active version of the standard.

Analysis of the data was conducted in accordance with Practices D and D and the adjunct Tex-Pac. No known procedure is available that can be used with all fabrics to determine the minimum tearing strength. The highest peaks appear to reflect the strength of the yarn components, fiber bonds, or fiber interlocks, individually or in combination, needed to stop a tear in a fabric of the same construction.

In d2621 of the empirical nature of the reported values, the values are considered to re? In the d2261 of such an agreement, take the number of fabric rolls speci?

The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated. For fabrics not readily wet out with water, such as those treated with waterrepellent or water-resistant materials, add a 0. There may be no overall correlation, however, between the results obtained with the CRT-type machine and the CRE-type machine.
