ISO 2477:2005 describes a method for determining the permanent change in dimensions on heating of a shaped insulating refractory product.
Abstract
Overview
ISO 2477:2005 specifies a standardized test method for determining the permanent change in dimensions on heating of shaped insulating refractory products. The procedure measures the residual dimensional change (shrinkage or expansion) when a shaped insulating refractory is heated in an oxidizing furnace to a prescribed temperature, held for a specified period, then cooled to ambient temperature. This method supports product quality control and material characterization for high-temperature insulating refractories.
