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. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM D SI units is the technically correct name for the system of metric units known as the International System of Units.

They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. 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.

Description Literature Contact Us Aramid cords are synthetically prepared and are stronger per weight than steel. Onsite Training At Your Facility.

It is the responsibility of the user of this standard to establish appropriate safety, aztm, and environmental practices and determine the applicability of regulatory limitations prior to use. Contact Us View Accessories Catalog. Combining values from the two systems may result in non-conformance with the standard. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Due to the unique surface finish of the jaws, they are able to grip the strong aramid cord in such sstm manner that limits internal slippage and provides more accurate and consistent results. In order to correct for this, higher air pressure can be used, but this could lead to jaw breaks, further jeopardizing the accuracy of the test results.

The values stated in either acceptable metric units or other units shall be regarded separately as standard.

ASTM D7269 Testing Aramid Cords: The Proper Grip

Although modulus may be determined at any specified force, initial modulus is the value most asrm used. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The methods include testing procedure only and include aztm specifications or tolerances. 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 respect to the grip.
