Test Method

Determination of Cold Crushing Strength of Insulating Refractory Products - Test Method - BS EN ISO 8895:2006


Shaped insulating refractory products. Determination of cold crushing strength.


Cold crushing strength is the maximum load per unit area, applied under specified conditions at room temperature, that a refractory product will withstand before failure occurs.


A test piece of known dimensions is subjected under specified conditions to a steadily increasing compressive load until its failure, when it cannot support a further increase in load.

The cold crushing strength is calculated from the maximum load indicated at failure and the mean cross-sectional area over which the load is applied.
