ASTM D / DM – 17 Standard Test Methods for Tensile Testing of Aramid Yarns

Looking at the differences in the results between the regular and aramid cord and yarn grips, it seems that the cords gripped with the regular grips exhibited asrm slippage in the jaw. Email addresses can only contain letters, numbers and the following special characters: It is a measure of the ability of a textile structure to absorb mechanical energy. By means of our tensile testing d72699 and modular product design, we will help find the solution that is right for you.

Testing conditions accordingly are specified precisely to obtain reproducible test results on a specific sample. As a minimum, test samples should be used that are aatm homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing.

This means that the fibers within the jaw slipped past one another, which jeopardizes the accuracy of the test results. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. How can we help you? Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Glossary of Materials Testing Terms.

ASTM D D determines the tensile testing of aramid yarns, cords twisted from such yarns, and fabrics woven from such cords.

The values stated in either acceptable metric units or other units shall be regarded separately as standard. It is not possible, therefore, to evaluate adtm performance of a textile reinforced product in terms of the reinforcing material alone.
