Test Method

Determination of Refractoriness Under Load - Test Method - BS EN ISO 1893:2008

Title

Methods of test for dense shaped refractory products. Determination of refractoriness-under-load.

Overview

Refractoriness under load is a measure of the behaviour of a refractory material subjected to the combined effects of load, rising temperature and time.

Principle

A cylindrical test piece is subjected to a specified contant compressive load and heated at a specified rate of temperature increase until a prescribed deformation or subsidence occurs. The deformation of the test piece is recorded as the temperature increases, and the temperatures corresponding to specified proportional degrees of deformation are determined.
