ASTM C20

1.1 These test methods cover the determination of the following properties of burned refractory brick:

1.1.1 Apparent porosity,

1.1.2 Water absorption,

1.1.3 Apparent specific gravity, and

1.1.4 Bulk density.

1.2 These test methods are not applicable to refractories attacked by water.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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.
