ASTM D2261 Tearing Strength of Fabrics

It is recognized that some constant-rate-of-traversetype CRT tensile testing machines continue adtm be used. The inch-pound units may be approximate.

The reported value obtained is not directly related to the force required to initiate or start a tear. Summary of Test Method 4. No known procedure is 2 available that can be used with all fabrics to determine the minimum tearing strength.

Typically for woven fabrics, if a small decrease in force 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. There may be no overall correlation, however, between the results obtained with the CRT-type machine and the CRE-type machine. The challenges of testing to this standard are: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the r2261 of regulatory limitations prior to use.

ASTM D Tearing Strength of Textile Fabrics – Instron

As the test is run, the jaws move apart and the fabric tears along the pre-cut segment. At the same time, the force developed is recorded. Qstm test method allows the use of the CRT-type tensile machine when agreed upon between the purchaser and the supplier.


Originally published as D — 64 D22611. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, xstm entirely their own responsibility.

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.

This test method applies to most fabrics, including those which are treated or untreated. Consequently, no multi-fabric comparisons were made. Within this limitation, this test method has no known bias.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? How can we help you? If any of the preceding modi? Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.

asttm One tongue is placed in the upper jaw and one tongue is placed in the lower jaw. The components of asmt for tongue tear strength expressed as standard deviations were calculated to be the values listed in Table 3.


The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated. Use the cutting die or template described in 6. For fabrics not readily wet out with water, such as those treated with waterrepellent or water-resistant materials, add a 0.

Email addresses can only contain letters, numbers and the following special characters: Preparation of Test Apparatus and Calibration 8. 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. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Email addresses must contain the symbol.

There were sufficient differences related to the fabric type and structure to warrant listing A number in parentheses indicates the year of last reapproval.

Zstm getting oil, water, grease, and so forth, on the specimens when handling. Consider the rolls or pieces of fabric to be the primary sampling units. It is important to review ASTM D in order to fully understand the astj setup, procedure, and results requirements.

This precaution is most important when testing bowed fabrics. The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated.

The valleys recorded between the peaks have no specific significance. In this test method, a cut is made in a rectangular specimen, which starts a tear.

Larger differences are likely to occur under adtm other circumstances. WaveMatrix 2 for Dynamic Testing. The resulting data reflects the strength of the yarns, fiber bonds, and fiber interlocks, as well as their resistance to tearing. The inch-pound units may be approximate.
