Historical Standard: ASTM C1171-05 Standard Test Method for Quantitatively Measuring the Effect of Thermal Shock and Thermal Cycling on Refractories
SUPERSEDED (see Active link, below)
ASTM C1171
1. Scope
1.1 This test method is used for determining the strength loss or reduction in continuity, or both, of prism-shaped specimens which are cut from refractory brick or shapes and subjected to thermal cycling.
1.2 The strength loss is measured by the difference in modulus of rupture (MOR) between uncycled specimens and the specimens subjected to thermal cycling.
1.3 The reduction in structural continuity is estimated by the difference in sonic velocity before and after thermal cycling.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values stated in parentheses are for information only.
1.5 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.
