ASTM D is a testing standard for those needing to test fabrics made from Acetate, Acrylic, Cotton, Flax, Nylon, Olefin, Polyester, Rayon, Silk, or Wool. ASTM D Tear strength of fabrics test to determine the resistance to the formation of pills and other related surface changes of textile fabrics using Tongue. Designation: D – 96 (Reapproved ) Standard Test Method for Tearing Strength of Fabrics by the Tongue (Single Rip) Procedure.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of d226 limitations prior to use.
The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated.
ASTM D Tearing Strength of Textile Fabrics – Instron
Competent statistical assistance is recommended for the investigation of bias. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Please confirm that you agree with our privacy and cookies policy to submit this form.
WaveMatrix 2 for Dynamic Testing. Manual clamping is permitted providing no slippage of the specimen is observed. The reported value obtained is not directly related to the force required to initiate or start a tear. This test method allows the use of the CRT-type tensile machine when agreed upon between the purchaser and the dd2261. The tearing force may increase to a simple maximum value, or may show several maxima and minima, as shown in Fig.
The challenges of testing to this standard are: Before a meaningful statement can be made about two speci?
Take the specimens to be used astk the measurement of machine direction with the longer dimension parallel to the cross-machine direction. 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. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Tear Strength of Fabrics – Tongue Tear (Single Rip)
This test method applies to most fabrics, including those which are treated or untreated. Label to maintain specimen identity. Competent statistical assistance is recommended for the investigation of bias. Four of the eight specimens were tested on one day, and four specimens were tested on a second day. The three fabric types were: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Description Literature Contact Us Originally introduced inthe latest version was released in Preparation of Test Apparatus and Calibration 8. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Take the specimens to be used for the measurement of the crossmachine direction with the longer dimension parallel to the machine direction.
The inch-pound units may be approximate.
ASTM D2261 Tearing Strength of Fabrics
Disengage the pawls from the rachet to render them inoperative. When testing to this standard, it is important to consider data rate. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Precision and Bias If a bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results with consideration to the known bias. Avoid getting oil, water, grease, and so forth, on the specimens when handling. No known procedure is 2 available sstm can be used with all fabrics to determine the minimum tearing strength.
Consequently, these test instruments may be used when agreed upon between the purchaser and the supplier. Discontinued November and reinstated as D No known astn is available that can be used with all fabrics to determine the minimum tearing strength.
Consequently, these two tensile testers cannot be used interchangeably unless the degree of quantitative correlation has been established between the purchaser and the supplier.
For fabrics not readily wet out with water, such as those treated with waterrepellent or water-resistant materials, add a 0. Concrete, Asphalt and Rock. There were sufficient differences related to the fabric type and structure to warrant listing The valleys recorded between the peaks have no speci? V2261 Us View Accessories Catalog. B Refer to
