ASTM C373 – Standard Test Methods for Determination of Water Absorption and Associated Properties by Vacuum Method for Pressed Ceramic Tiles and Glass Tiles and Boil Method for Extruded Ceramic Tiles and Non-tile Fired Ceramic Whiteware Products
Description:
Significance and Use
3.1 Measurement of density, porosity, and specific gravity is a tool for determining the degree of maturation of a ceramic body, or for determining structural properties that may be required for a given application.
Scope
1.1 These test methods covers procedures for determining water absorption, bulk density, apparent porosity, and apparent specific gravity of non-tile fired unglazed ceramic whiteware2 products, glazed or unglazed ceramic tiles, and glass tiles.
1.2 The values stated in metric units are normative. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not normative.
