This Standard describes a procedure for determining the resistance to thermal shock of a refractory when a face is exposed to specified temperature fluctuations in a prescribed manner.This Standard is applicable to all dense, prefired refractories that-(a) are chemically stable in an oxidizing atmosphere;(b) when tested in accordance with AS 1774.3 have a modulus of rupture not less than2 MPa; and(c) are large enough for test specimens of the required dimensions to be cut.NOTE: The thermal shock conditions specified in this Standard may not be severe enough for testing special refractories such as silicon carbides.
