TestResources has advanced experience in the biomedical field. No other units of measurement are included in this standard.

Instead, the user should only select test methods that are appropriate for a particular device design. 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.

In most instances, only a subset of the herein described test methods will be required. Bone plates are used during orthopedic orthopaedic reconstructive surgery for alignment c382 fixation of bone segments. This specification and test method establishes the consistent methods for classifying, and defining the geometric and f3822 characteristics of five types cloverleaf, cobra head, asrm, straight, and tubular of metallic bone plates used in the surgical internal fixation of the skeletal system.

By means of our biomedical testing expertise and modular product design, we will help find the testing solution that is right for you. The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates. Therefore, the method is not applicable for testing bone plates made from materials that exhibit non-linear elastic behavior. There are instances when we test prototypes and new devices without an established test specification.

Make an inquiry today. This article is geared towards asym plate testing within the medical device industry.

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. When working with the FDA or another regulatory body, one will have to justify their reason for deviating from a specification.

This abstract is a brief summary of the referenced f38. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Either way, there are appropriate occasions when the user may deviate from a v382 standard. Some specimens are unusual in shape, size and function. View more articles about More Sectors. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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 is cautioned to consider the appropriateness of the standard in view of a particular bone plate and its potential application. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. There are many steps a Test Engineer or Technician can take early in the testing stages to avoid the painful woes of mechanical testing.

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 should follow the standard as closely as possible when dealing with irregular geometries and ASTM F provides guidelines for this case. No other units of measurement are included in this standard.

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.

Have a question about conducting the test for this standard? Rollers are available in various sizes for different size bone plates. However, it must be noted that the user is not obligated to test asm all of the described methods.

The strength and stiffness of the plate allows the bone to heal while providing structural support. If the test data is for internal use, then one can deviate more loosely. 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.

We offer machines, asrm, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

ASTM F – Instron

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.

The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates. The four point flexural bend fixture consists of two loading rollers near the center and two support rollers at the ends of atsm fixture. The convex surface, where accompanying bone screws will be inserted, asrm face downward, towards the support rollers. Link to Active This link will always route to the current Active version of the standard.

The standard also presents a catalog of standard specifications that specify awtm 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.
