Leak Testing for Medical and Diagnostic Equipment Explained Two areas of medical device manufacture require leak detection for quality assurance: product testing and packaging testing. Product testing includes verifying the function of devices, flow paths, valves and assembly integrity. Pack testing is about ensuring the sterility of the devices, or other protective requirements such as low humidity, during their shelf lives. The test methods in ...
