Medical Materials Testing

Introduction

The physical testing of medical materials is generally handled the same as other material applications and other sections of this web site apply. However there is the unique requirement that materials sometimes be tested in Saline at body temperature or in water at ocular temperature. Additional considerations may be required for physically small or very soft materials that occur regularly in medical applications.

This section:

  • Testing in Saline Solution
  • Testing Materials at Low Forces


  • Testing in Saline Solution

    Material testing in saline requires the use of saline recirculation and non-contact strain measurement.

    Testing Materials at Low Forces

    Testing at low forces require low force load cells and very low mass gripping systems. In addition, very soft materials need non-contacting strain measurement.
