Hence, the test environment, whether a simulated body fluid, saline 9g NaCl per mL H 2 Owith a saline drip, or dry, is an important characteristic of the test and must be reported accurately. One side of the longitudinal element is firmly clamped aastm the other side remains free. Subscription pricing is determined by: The connecting element serves as a lever arm, so that a moment about the x- or y-axis is generated.
This standard is not included in any packages. Please first verify your email before subscribing to alerts.
If the document is revised or amended, you will be notified by email. A force-displacement curve reveals a significant drop in force, which marks the exceeding of the connection strength.

We offer various test methods for the mechanical characterization of partial constructions of spinal implants according to ASTM F Accreditation certificate arrived Need more than one copy?
Historical Version s – view previous versions of standard. This test method outlines standardized evaluations of different interconnection mechanisms to facilitate comparison between different designs. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. As the voice of the U. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct.
Your Alert Profile lists the documents that will be monitored. The force-displacement curves are recorded and evaluated with regard to the mechanical properties including stiffness and strength. From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants: You may delete a document from your Alert Profile at any time.
From the following range, we will select the appropriate test procedures for the partial constructs of your individual spinal implants:. Comparisons must be made cautiously and with careful analysis, taking into account the effects that design differences can have on the loading configurations.
In this test, the connection stability between the connecting element and the longitudinal element is determined. Link to Active This link will always route to the current Active version of the standard.
Referenced Documents purchase separately The documents listed below v1798 referenced within the subject standard but are not provided as part of the standard.
Within the scope of the test, loads and moments are applied in three directions corresponding to a vertebral body: Dynamic test methods Following the static tests, the tests with new test specimens are performed dynamically over 2.
ASTM F1798 – 13
However, the results can be used to compare different component designs in terms of relative mechanical parameters. Remember me for one month.
F Terminology Relating to Spinal Implants. There were no books found for the applied search filters. The mechanical tests are conducted in vitro using simplified, unidirectional loads and moments. The longitudinally proceeding component is firmly clamped in the test device asmt a load max. If you like to setup a quick demo, let us know at support madcad.

Wirbelsäulenimplantate – Verbindungs- und Teilkonstrukte ASTM F
It is not the intention of this guide to address the analysis of spinal implant constructs or subconstructs or to define levels of performance of spinal implants as insufficient knowledge is available to predict the consequences of the use of particular spinal implant designs. Ultimately, the various components and interconnections should be combined for static and fatigue testing of the spinal implant construct.
This standard is also available to be included in Standards Subscriptions. Land Use and Development.

If the partial construct fails before reaching the 2. Following the dynamic tests, the axial joint strength is tested under torsion to determine residual stability. Please first log in with a verified email before subscribing to alerts.
