This tester combines tensile and compression (pulling and pushing a test specimen) with a torque action (twisting). For the orthopedic industry, it is mainly used for fatigue or cycle testing.
"While we have had the ability to carry out limited orthopaedic tests using our universal testers we can now more completely address a growing market in the medical device industry," said Mark Francis, DDL's product and material division lab manager.
Some of the orthopedic test standards that DDL can now perform include:
• ASTM F2193, Standard specifications and test methods for components used in the surgical fixation of the spinal skeletal system;
• ASTM F1717, Standard test methods for spinal implant constructs in a vertebrectomy model;
• ASTM F56, Standard specification and test methods for metallic bone staples;
• ISO 7206-4, Implants for surgery—partial and total hip joint prostheses—Part 4: Determination of endurance properties and performance of stemmed femoral components; and
• ISO 14801, Dentistry implants: Dynamic fatigue test for endosseous dental implants.
"Some orthopedic testing is customized for our clients and DDL's technical experts are able to consult on a one on one basis in order to provide the best device testing solution possible." Francis said. "We look forward to working with more customers in this expanding market."
DDL has three full-service labs offering testing services that include shock testing, vibration testing, tensile testing, leak testing and validation services.
