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.

How can adtm help you? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? NOTE 2—The tabulated values of the critical differences should be considered to be a general statement, particularly with respect to betweenlaboratory precision.
The highest peaks appear to re? Take the specimens to be used for the measurement of the crossmachine direction with the longer dimension parallel to the machine direction.
ASTM D Tear Strength of Fabrics – Tongue Tear (Single Rip)
Consequently, these two tensile testers cannot be used interchangeably unless the degree of quantitative correlation has been established between the purchaser and the supplier. Perform the test within 2 min after removal of the specimen from the water. Use the cutting die or template described in 6.
Tear Strength of Fabrics – Tongue Tear (Single Rip)
The minimum tearing force, however, is indicated to be above the lowest valleys. The challenges of testing to this standard are: At the same time, the force developed is recorded.
WaveMatrix 2 for Dynamic Testing. Make a preliminary cut 75 mm 3 in.
ASTM D2261 Tearing Strength of Fabrics
The reported value obtained is not directly related to the force required to initiate or start a tear. If any of the preceding modi? Historical Version s – view previous versions of standard. The valleys recorded between the peaks have no specific significance. The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated. Subscribe to Instron News! Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
When testing to this standard, it is important to consider data rate. Competent statistical assistance is recommended for the investigation of bias.
In any event, the CRE-type machine shall prevail. B Refer to The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated. 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.
The separation of the jaws is continuously increased to apply a force to propagate the tear.

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.
Within this limitation, this test method has no known bias.
