Standard Test Method for Moisture Expansion of Fired Whiteware Products
2020
2
ASTM Vol.15.02 (2022)
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.
