Repeating all or part of these test methods in simulated body fluid, saline 9 g NaCl per mL watera saline drip, water, or a lubricant should be considered. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Subscribe to Instron News! Anatomical parameters depending on the spinal level were compared to published data or measurements on biplanar stereoradiography on 13 patients.
Active ff current version of standard. Onsite Training At Your Facility. For application of torsional strain, we recommend any of our torsion tabletop testing systems. Next Checking to see if you are a returning visitor…. The American Society for Testing and Materials reapproved F standard for the assessment of mechanical properties of posterior spinal fixators, which simulates a vertebrectomy model and recommends mimicking vertebral bodies using polyethylene blocks.
We are confident that we have what you are looking for. The 55MT MicroTorsion system can be used when multiple revolutions are required.
Additionally fatigue tests are employed to quantify the static and dynamic mechanical characteristics of different designs of spinal implant assemblies. Email addresses can only contain letters, numbers and the following special characters: 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 purchase, operating, and mantenance costs than hydraulic equivalents.
Have a question about conducting the test for this standard? Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water. The maximum recommended frequency for this type of cyclic testing should be 5 Hz.
The ElectroPulsTM E Linear-Torsion is a state-of-the-art, all-electric test instrument designed for g and static testing on a wide range of materials and components. They allow comparison of spinal implant constructs with different intended spinal locations and methods of application to the spine.
The worst-case combination of parameters demonstrates that devices implanted below T5 could potentially undergo higher stresses than those described in the standard suggestions maximum increase of The effect of environment may be significant.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental 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.
