This Standard sets out the evacuation method and the boiling water method for determining the following properties of a refractory:(a) Bulk density.(b) Apparent solid density.(c) Apparent porosity.(d) Water absorption.The evacuation method is applicable to all refractories. The boiling water method is applicable only to refractories which are unaffected by boiling water and should not be used where the resistance to boiling water is in doubt.In addition it sets out a method for determining bulk density by direct measurement of mass and volume and provides equations from which, after determining true density by AS 1774.6, the following may be calculated:(i) True porosity.(ii) Sealed porosity.The direct measurement method for determining bulk density is applicable only to regular shaped specimens having a volume of at least 0.001 m3.
