Over deze norm
1.1 These test methods cover the determination of the following properties of refractory shapes:
1.1.1 Apparent porosity,
1.1.2 Liquid absorption,
1.1.3 Apparent specific gravity, and
1.1.4 Bulk density.
1.2 These test methods are applicable to all refractory shapes except those that chemically react with both water and mineral spirits. When testing a material capable of hydration or other chemical reaction with water but which does not chemically react with mineral spirits, mineral spirits is substituted for water and appropriate corrections for the density differences are applied when making calculations.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3.1 Exception—The apparatus used in this standard is only available in SI units.
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.
Note 1: Test Methods cover procedures for testing properties of refractories that are not attacked by water.
