Pressurized Internal Diameter
Determination of internal diameter under simulated physiological conditions of the same order of magnitude as the arterial blood pressure: 120 mmHg.
Test Procedure
Samples are extended to their functional length. Specified pressure is applied uniformly to the inside of a prosthesis which is extended to its usable length. A cylindrical balloon mounted over a cylindrical mandrel is used. An optical measurement system is used to measure external diameter.
