Pin-on-Disc Testing

Standards We Test

ASTM F732

Standard Test Method for Wear Testing of Polymeric Materials Used in Total Joint Prostheses

ASTM F2025

Practice for Gravimetric Measurement of Polymeric Components for Wear Assessment

Service Overview

Pin-on-disc (POD) testing is a cost-effective preliminary screening method that yields valuable information regarding material wear characteristics and durability. POD testing can be used for screening candidate material couples  to optimizing product design and performance prior to real-world application.

We use a six-station OrthoPOD system developed and manufactured by Advanced Mechanical Technology Inc. (AMTI). Pin rotation, disc rotation, and dynamic pin loading are all independently controlled. In addition, track patterns and loads can be customized and are fully programmable. Equipment specifications are provided below.
