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

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. Although the ASTM F Four Point Bend test standard may seem very straight forward, there are specific guidelines the user must follow in order to maintain test validity.
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. The user is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application.
Roller dimensions are another important factor. Therefore, the method is not applicable for testing bone plates made from materials that exhibit non-linear elastic behavior.
Know when to deviate, and when ast to. When comparing test results of prototype devices and predicate devices, make sure the tests were conducted in a similar fashion, without major deviations or differences in test setup, the specimen, and method in which data was collected and analyzed.
If the test data is for internal use, then one can deviate more loosely. There are instances when we test prototypes and new devices without an established test specification.
Plate bending ASTM F
No other units of measurement are included in this standard. By means of our biomedical testing expertise and modular product design, we will help find the testing solution that is right for you. Astmm, the test method may be used to estimate a bone plate’s fatigue strength for a specified number of fatigue cycles. Three general items come to mind when performing any mechanical test.
Instead, the user should only asmt test methods that are appropriate for a particular device design.
Important Guidelines for ASTM F382 Bone Plate Testing
The user should follow the standard as closely as possible when dealing with irregular geometries and ASTM F provides guidelines for this case. This test method may be used to determine a fatigue life of the bone plate at either a specific maximum bending moment or over a range of maximum bending moment conditions. Become familiar with the test standard in order to perform the test accurately.
There are occasions when the test must deviate from the spec in order to successfully carry out the experiment. Perfect the test setup. 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.

Either way, there are appropriate occasions when the user may deviate from a test standard. Have a question about conducting the test for this standard? Futhermore, it is not the intention of the standard to describe or specify specific designs for bone plates used in the surgical internal fixation of the skeletal system. Historical Version s – view previous versions of standard. 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.
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 strength and stiffness of the plate allows the bone to heal while providing structural support.

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. We are confident that we have what you are looking for.
The standard establishes consistent methods to f328 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. Rigid extension segments work well to sufficiently lengthen small bone plates so that they can be tested per the four point bend method.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates. Futhermore, it is not the intention wstm the standard to describe or specify specific designs for bone plates used in the surgical internal fixation of the skeletal system.
Bending strength and stiffness information and fatigue life of the device are determined in this specification.
