ASTM C484-99(2003)

Standard Test Method for Thermal Shock Resistance of Glazed Ceramic Tile

SIGNIFICANCE AND USE
This test method is intended for testing glazed ceramic tile that are to be used in areas in which they may be subjected to rapid or severe temperature changes.
SCOPE
1.1 This test method covers the determination of the resistance to thermal shock of glazed ceramic tiles under normal conditions of use.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
