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

This neither defines the levels of performance or case-specific clinical performance for bone plates, nor describes specific designs for bone plates.
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. Instead, the user should only select test methods that are appropriate for a particular device design.
ASTM F – 14 Standard Specification and Test Method for Metallic Bone Plates
In most instances, only a subset of the herein described test methods will be required. However, it must be noted that the user is not obligated to test using all of the described methods.
The user should be aware of items that will influence the outcome of a 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.

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.
We are confident that we have what you are looking for. Astj standard also presents a catalog of standard specifications that specify material; labeling and 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 data generated from this test method can be used to conduct relative comparisons of different bone plate designs. Abnormally shaped bone plates will obviously be much trickier to set up and test.
ASTM F382 Flexural Fatigue Bone Plate Fixation Devices Test Equipment
No other units of measurement are included in this standard. 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 maintenance costs than hydraulic equivalents.
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. Bending strength and stiffness information and fatigue life of the device are determined in this specification.
Alternatively, the test method may be used to estimate a bone plate’s fatigue strength for a specified number of fatigue cycles. Rollers are available in various sizes for different size bone plates. This article is geared towards bone plate testing within the medical device industry. No other units of measurement are included in this standard. Futhermore, it is not the intention of the standard to f328 or specify specific designs for bone plates used in the surgical internal fixation of the skeletal adtm.

ASTM F – 17 Standard Specification and Test Method for Metallic Bone Plates
Perfect the test setup. The user is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application. The user should follow the standard as closely as possible when dealing with irregular geometries and ASTM F provides guidelines for this case.
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 standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates. Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Know when to deviate, and when not to. Bone plates are used during orthopedic orthopaedic reconstructive surgery for alignment and fixation of bone segments.
The concave surface of the bone plate which will come into contact with the bone during surgery should face upward in testing, toward the load rollers. This abstract is a brief summary of the referenced standard.
