ASTM D Testing Aramid Cords: The Proper Grip – Instron
When internal slippage occurs, the cord is weakened for obvious reasons. Subscribe to Our Newsletters. 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 internal slippage in the jaw.
Software for Series Systems. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. 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.
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. Onsite Training At Your Facility. It is not possible, therefore, to evaluate the performance of a textile reinforced product in terms of the reinforcing material alone.
Combining values from the two systems may result in non-conformance wstm the standard.
