ASTM D/DM: Standard Test Methods for Tensile Testing of Aramid Yarns. ASTM D (D) determines the tensile testing of aramid yarns, cords twisted from such yarns, and fabrics woven from such cords. The yarn or cord may. How do you test yarn tensile strength for your application? Learn about ASTM D and how it compares to ASTM D in this basic test.

Testing conditions accordingly are specified precisely to obtain reproducible test results on a specific sample. Active view current version of standard. 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.
ASTM D / DM – 10 Standard Test Methods for Tensile Testing of Aramid Yarns
Inch-pound units is the technically correct name for the customary units used in the United States. Due to the unique surface finish of the jaws, they are able to grip the strong aramid cord in such a manner that limits internal slippage and provides more accurate and consistent results. Glossary of Materials Testing Terms.
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 c7269 to use.
SI ashm is the technically correct name for the system of metric units known as the International System of Units. The aramid cord and yarn grips did not exhibit symptoms of internal slippage.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Shape, size, and internal construction also can have appreciable effect on product performance. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. The asstm length of the specimen was set to mm.
The methods include testing procedure only and include no specifications or tolerances. Bluehill LE for Basic Testing.
WaveMatrix 2 for Dynamic Testing. Looking at the differences in d729 results between the regular and aramid cord and yarn grips, it seems that the cords gripped with the regular grips exhibited internal slippage in the jaw. Other materials with established test values may be used for this purpose.
The yarn or cord may be wound on cones, tubes, bobbins, spools, or beams; may be woven into fabric; or may be in some other form.
Give our test engineers a call today ast, help configuring the best test machine and accessories according to ASTM D The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Link to Active This link will always route aetm the current Active version of the standard. Subscribe to Instron News! When internal slippage occurs, the cord is weakened for obvious reasons.
Historical Version s – view previous versions of standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. Contact Us View Accessories Catalog. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The yarn or cord may be wound on cones, tubes, bobbins, spools, or beams; may be woven into fabric; or may be in some other form.
To check for slippage, we attached flags of tape to the ends of the cord and monitored them to make sure there was no relative movement of the flag with asgm to the grip. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of each other, without combining values in any way.

How can we help you?
It is not possible, therefore, to evaluate the performance of a textile reinforced product in terms of the reinforcing material alone. Although modulus may be determined at any specified force, initial modulus is the value most commonly used. We are confident that we have what you are looking for. The methods include testing procedure only and include no specifications or tolerances. Breaking toughness is work-to-break per unit mass. The yarn or cord may be wound on cones, tubes, bobbins, spools, or beams; may be woven into fabric; or may be in some other form.
They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. d726
