Standard Test Method for Moisture Expansion of Fired Whiteware Products
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the elongation of whiteware bodies caused by rehydration as a result of autoclave treatment.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
This test method provides means to determine increases in physical dimension of fired whiteware materials which develop from the reaction of water and water vapor at elevated pressures and temperatures. These reactions can occur in time at normal atmospheric pressures and temperatures; changes in physical dimensions from water can influence the integrity and stability of an installation. In the case of glazed ware, moisture expansion can lead to crazing.
