Wear properties of ceramics PI-60 (ISO 6474)

PI-60: (ISO 6474; 1994) Implants for surgery – Ceramic materials based on high purity alumina

This wear test is designed as a screening test to evaluate tribologic properties of new designed implant materials or combinations. A ring (20 mm diameter) is oscillated at a 25° rotational movement on a disc (25 mm diameter). Water is used as test fluid but bovine serum or Ringer´s solution can be used optionally. The test is stopped after 100 hours at 1 Hz frequency. The amount of wear is determined by profile measurement of the wear track. EndoLab® GmbH uses a computerized method to gain 3-D results of the wear track. Due to the simplification of the kinematics in-vivo, more complex test procedures like joint simulators have to be used to obtain further information.

email problems with office 365
Dear clients & partners,

Since the end of January, we have heard from some clients who use Office 365 that they are experiencing trouble receiving our emails. Our emails seem to be classified as phishing attempts and, therefore, never reach their inboxes.

If you are also waiting for a reply, please call us at +49 8031 2313230!

We look forward to hearing from you again and hopefully re-establish full communication.

The EndoLab Team
