Standard Test Method for Small Punch Testing of Polymeric Biomaterials Used in Surgical Implants

Importancia y uso:

4.1 Miniature specimen testing techniques are used to characterize the mechanical behavior of polymer stock materials and surgical implants after manufacture, sterilization, shelf aging, radiation crosslinking, thermal treatment, filler incorporation, and implantation (1-3). Furthermore, experimental materials can be evaluated after accelerated aging, fatigue testing, and hip, knee, or spine wear simulation. Consequently, the small punch test makes it possible to examine relationships between wear performance and mechanical behavior. This test method can also be used to rank the mechanical behavior relative to a reference control material.

4.2 Small punch testing results may vary with specimen preparation and with the speed and environment of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled.
