For this test, it is important to have an increased test data rate to ensure the capture a high number of data points. Work Item s – proposed revisions of this standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Active view current version of standard. The average results from the two laboratories should be compared using Student’s t -test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun.
The breaking force determined by the grab procedure is not a reflection of the strength of the yarns actually gripped between clamps and cannot be used for direct comparison with yarn strength determinations.
ASTM D Breaking Strength and Elongation of Textile Fabrics Grab Test – Instron
Work Item s – proposed revisions of this standard. Historical Version s – view previous versions of standard. This is because when individual fibers within the fabric fail, the data rate must be fast enough to catch these peaks. This test method is particularly applicable to high-strength fabrics.
The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. Rapid data capture rate with Instron’s controller allows data peaks qstm valleys to be captured accurately at up to 2, points per second Instron pneumatic side action grips with rubber faces are well-suited to gripping nearly all types of fabric specimens for this test while maintaining high atm It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
How can we help you? The values stated in either acceptable metric units or in other units shall be regarded separately as standard. Bluehill LE for Basic Testing. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.
The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining in any way.
ASTM D5034 Textile Strength and Elongation Grab Test
Grab test specimens require much less time to prepare although they require more fabric per specimen. 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 in light of the known bias. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
Provisions are made for wet testing. Competent statistical assistance is recommended for the investigation of bias. WaveMatrix 2 for Dynamic Testing.

Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: 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. Adjustable grip pressure also allows users to fine-tune the gripping pressure to avoid jaw breaks or slippage.
