Standard Test Method for Linear Dimensional Stability of a Gasket Material to Moisture

Importancia y uso:

3.1 Gasket materials undergo several processing steps from point of manufacture to installation in a flange. Many applications require close control of dimensional change. An accurate test method for determining the relative stability of various materials is needed for design and quality assurance purposes. This test method is useful towards that end. It simulates the extreme storage conditions that a material may undergo prior to installation. Samples are allowed unrestricted expansion or contraction, and so this test method should not be used to predict behavior clamped in a flange or other applications, or during specific processing steps.

3.2 This test method measures linear change, and may need to be modified if the test specimen is not flat, homogeneous, or free of voids.
