ASTM C 134 : 1995 : R1999

1.1 These test methods cover procedures for measuring size, dimensional measurement, bulk density, warpage, and squareness of rectangular dense refractory brick and rectangular insulating firebrick. More precise determination of bulk density of refractory brick can be made by Test Methods C20. Stack height is generally determined only for dense refractories.

Note 1--Test Methods C830 and C914 are also used to determine bulk density of refractory brick, by different procedures.

1.2 The test methods appear in the following order:

1.3 The values stated in inch-pound units are to be regarded as standard. The values in parentheses are provided as 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.
