Software for Series Systems. The maximum recommended frequency for this type of cyclic testing should be 5 Hz. Our universal testing systems are asstm for static tensile and compressive tests. Subscribe to Instron News! These test methods outline standard materials and methods for the evaluation of different spinal implant assemblies so that comparison between different designs may be facilitated.
Powered entirely from a single-phase mains supply, they feature the latest in testing technology and a host of other user-oriented features. The standard set-up represents quite well the anatomy of an instrumented average thoracolumbar segment. They allow comparison of spinal implant constructs with different intended spinal locations and methods of aztm to the spine. During normal astn activity, spinal constructs can be subjected to high in vivo loading that can result in catastrophic failure.
Email addresses can only contain letters, numbers and the following special characters: Simple static testing is able to evaluate the load required to result in spinal fracture.

ASTM F, Testing of Spinal Constructs, Static, Fatigue, Torsion – Instron
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. The results can be used to compare different component designs in terms of the relative mechanical parameters. For the majority of spinal construct testing, ultra high molecular weight polyethylene UHMWPE blocks are used rather than vertebrae to eliminate the variances that bone properties and geometry may introduce.
Next Checking to see if you are a returning visitor…. The mechanical tests are conducted in vitro using simplified load schemes and ast not attempt to mimic the complex loads of the spine.
Bluehill LE for Basic Testing. The 55MT MicroTorsion system can be used when multiple revolutions are required. Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water.
The results obtained here cannot be used directly to predict in vivo performance. It is the responsibility of asfm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The test materials for most combinations of spinal implant components can be specific, depending on the intended spinal location and intended method of application to the spine. Methods for three static load types and one fatigue test are defined for the comparative evaluation of spinal implant assemblies.

Static and fatigue forces up to 50 kN 11, lbf Frequency ratings up to 75 Hz Oil-free, all electric actuator for clean test conditions Lower aatm, operating, and mantenance costs than hydraulic equivalents.
The test materials for most combinations of spinal implant components can be specific depending on the intended spinal location and intended method astj application to the spine.
ASTM F1717 Spinal Implant Static and Fatigue Test Equipment
Anatomical parameters depending on the spinal level were compared to published data or measurements on biplanar stereoradiography on 13 patients. Please confirm that you agree with our privacy and cookies policy to submit this form. The ElectroPulsTM E Linear-Torsion is a state-of-the-art, all-electric test instrument designed for dynamic and static testing on a wide range of materials and components.
For application of torsional strain, we recommend any of our torsion tabletop testing systems.
