ISO 13765-3:2004 PDF

Overview

ISO 13765-3:2004 specifies a laboratory test method for determining the joint stability of refractory mortars. The standard describes how to prepare and lay mortar between refractory bricks, the apparatus and environmental controls required, and the procedure for measuring the time during which a mortar joint remains stable when one brick is moved by hand without breaking the joint. This test is used as part of quality control and product characterization in the refractory industry.
