Biological material testing encompasses a wide range of testing of both natural and synthetic analogues of natural materials. Examples of natural materials are bones, tissues, fibers of animals and humans, as well as stems, branches and leaves of plants. For all practical purposes biological material, more specifically biological tissues, are broadly classified into soft and hard tissues. Hard tissues include bones, teeth, other skeletal and exoskeletal muscles from humans and animals as well as wood stem from plants. Mechanical properties such as bearing strength and flexure of hard tissues are generally required for assessment of implants in health care industries.

Capability – Touchstone Testing Lab has capability to evaluate mechanical performance of hard tissues and their synthetic analogues. We have test frames with load capability from a few milli-Newtons to several kilo-Newtons to assess bearing properties, flexure properties and hardness of hard tissues such as bone, plant stems, etc. We can run these tests under corrosive environments to assess the impact of biological fluids on the hard tissues.

Some relevant standards:

• ASTM F382 – Standard Specification and Test Method for Metallic Bone Plates
• ASTM F451 – Standard Specification for Acrylic Bone Cement
• ASTM F543 – Standard Specification and Test Methods for Metallic Medical Bone Screws
