Abstract

This document specifies a method for the determination of the bulk density, apparent porosity and true porosity of dense shaped refractory products.

Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products.

This document is also applicable to unshaped refractories (see ISO 1927-6) after preparation of test specimens according to ISO 1927-5.

NOTE            For shaped insulating refractory products, the bulk density and true porosity are determined in accordance with ISO 5016.
