DDL, a provider of medical device package, product and material testing, has expanded their testing capabilities with the addition of orthopaedic testing. DDL's ability to perform the orthopaedic testing came with the recent purchase of a biaxial tester.
This tester combines tensile and compression (pulling and pushing a test specimen) with a torque action (twisting). For the orthopaedic industry it is mainly used for fatigue or cycle testing.
Some of the orthopaedic test standards that DDL can now test 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, etc. (Source: Healthcare Packaging)
