Standard Test Method for Compressibility and Recovery of Laminated Composite Gasket Materials

Importancia y uso:

3.1 This test method is designed to compare related laminated composite gasket materials under controlled conditions and their short-time compressibility and recovery at room temperature. It measures compressibility with a matched pair of opposing upper and lower penetrators which provide better precision and bias than methods using an upper penetrator and a lower anvil. It is difficult to prepare undistorted test specimens from laminated composite gasket materials which will lay flat on an anvil. Also, with many composites having rigid inner layers the load on the upper penetrator is distributed over the bottom anvil area resulting in a lower than actual compressibility reading. This test method may be used as a routine test method when agreed upon between the purchaser and the producer.
