This document describes the method for determining the permanent change in dimensions on heating (drying and/or firing) of refractory mortars.
Abstract
Overview
ISO 13765-7:2021 - Refractory mortars: Determination of permanent change in dimensions on heating specifies a laboratory method to measure the permanent dimensional change (shrinkage or expansion) of refractory mortars when subjected to . The procedure quantifies dimensional stability after heating by measuring distances between marks on mortar-bonded refractory bricks before and after heat treatment and expressing changes as percentage values.
