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

The 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The convex surface, where accompanying bone screws will be inserted, should face downward, towards the support rollers. 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.
Roller dimensions are another important factor. No other units of measurement are included in this standard.
Important Guidelines for ASTM F Bone Plate Testing | Element
The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates. ASTM does not give any warranty express or implied or make any representation that the axtm of this abstract are accurate, complete or up to date.
Therefore, the test method is asmt applicable for testing bone plates under conditions that would approach or exceed the bending strength 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.
This neither defines the levels of performance or case-specific clinical performance for bone plates, nor describes specific designs for bone plates. By means of our biomedical testing expertise and modular product design, we will help find the testing solution that is right for you.
Important Guidelines for ASTM F382 Bone Plate Testing
Your test setup will undoubtedly have an impact on your mechanical testing results. The user is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application.
By Engaged Expert Maciej Jakucki. This article is geared towards bone plate testing within astk medical device industry. 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.
When working with the FDA or another regulatory body, one will have to justify their reason for deviating from a specification. However, it must be noted that the user is not obligated f328 test using all of the described methods.
For testing bone platesuse your best judgment — but also consult with the plate designer and any regulatory officials. TestResources has advanced experience in the biomedical field. View more articles about More Sectors Find related articles to you through the Nucleus.
Historical Version s – view previous versions of standard. ASTM F covers testing methods for mechanical properties of metallic bone plates. The user is cautioned to consider the appropriateness of the method in view of the devices being tested and their potential application.
As Mechanical Testing Engineers we can provide valuable insight into when to deviate from a test specification and when not to. The four c382 flexural bend fixture consists of two loading zstm near the center and two support rollers at the ends of the fixture.
We are confident that we have what you are looking for. View more articles about More Sectors. F suggests using rollers of equal diameters within the range of 6 to 12 mm. The user is cautioned to consider the appropriateness of the asm in view of a particular bone plate and its potential application. No other units of measurement are included in this standard. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom ff382 for unique applications.
Bone plates are used during orthopedic awtm reconstructive surgery for alignment and fixation of bone segments. Perfect the test setup. The strength and stiffness of the plate allows the bone to heal while providing structural support. 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.
