ASTM F Flexural Fatigue Testing Metallic Bone Plates. After orthopedic reconstructive ASTM F Metallic Angled Orthopaedic Fracture Fixation Devices. Although ASTM F (Four Point Bend) test standard may seem very straight forward, there are specific guidelines you must follow to maintain. Metallic Bone Plates need to undergo several tests before gaining approval as internal fixation devices of the skeletal system. One standard, ASTM F

Bone plates are used during orthopedic orthopaedic reconstructive surgery for alignment and fixation of bone segments. The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates.

The strength and stiffness of the plate allows the bone to heal while providing structural support. TestResources has advanced experience in the biomedical field. The user is cautioned to consider the appropriateness of the method in view asttm the devices being tested and their potential application. However, it must be noted that the user is not obligated wstm test using all of the described methods.

Have a question about conducting the test for this standard? Abnormally shaped bone plates will obviously be much trickier to set up and test. Therefore, the test method is not applicable for testing bone plates under conditions that would approach or exceed the bending strength of the bone plate being tested.

The user should follow the standard as closely as possible when dealing with irregular geometries and ASTM F provides guidelines for this case. While on the subject of test setup, we should also discuss the use of rigid extension segments. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability f3822 regulatory limitations prior to use.

The standard also presents a catalog of standard specifications that specify material; labeling ff382 handling requirements; and standard test methods for measuring performance related mechanical characteristics determined to be important to the in vivo performance of bone plates.

The user is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application. Alternatively, the test method may be used to estimate a bone plate’s fatigue strength for a specified number of fatigue cycles.

Important Guidelines for ASTM F382 Bone Plate Testing

We are confident that we have what you are looking for. The convex surface, where accompanying bone screws will be inserted, should face downward, towards the support rollers.

Your test setup will undoubtedly have an impact on your mechanical testing results. This neither defines the levels of performance or case-specific clinical performance for bone plates, nor describes asmt designs for bone plates. View more articles about More Sectors. Instead, the user should only select test methods that are appropriate for a particular device design. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Therefore, the method is not applicable for testing bone plates made from materials that exhibit non-linear elastic behavior. In most instances, only a subset of the herein described test methods will be required. Link to Active This link will always route to the current Active version of the 3f82. 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.

Perfect the test setup.

There are many steps a Test Engineer or Technician can take early in the testing stages to avoid the painful woes of mechanical testing. This article is geared towards bone plate testing within the medical device industry.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The user should be aware of items that will influence the outcome of a test. This abstract is a brief summary of the referenced standard. This specification and test method establishes the consistent methods for classifying, and defining the geometric and performance characteristics of five types cloverleaf, cobra head, reconstruction, straight, and tubular of metallic bone plates used in the surgical internal fixation of the skeletal system.

The user should note that the test results generated by this test method can not be used to directly predict the in vivo performance of the bone plate being tested. Also presented here are catalogs of standard specifications for material, labeling, and handling requirements, and standard test methods for measuring performance related mechanical single cycle bend and bend fatigue characteristics determined to be important to the in vivo performance of bone plates.

There are instances when we test prototypes and new devices without an established test specification.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F ASTM F covers testing methods for mechanical properties of metallic bone plates.

The standard calls for a special TestResources test fixture GF that replicates bending movement in a single cycle test, as well as fatigue evaluation of the plate design. Three general items come to mind when asstm any mechanical test. The four point flexural bend fixture consists of two loading rollers near the center and two support rollers at the ends of the fixture.

Plate bending ASTM F

Roller dimensions are another important factor. The user is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application. For ASTM F testing, the orientation of the bone plate will have a direct effect on the strength of the part in a four point bend scenario. Either way, there are appropriate occasions when the user may deviate from a test standard.
