Refractory products - Determination of refractoriness under load - Differential method with rising temperature

ISO 1893:2007 specifies a method for determining the deformation of dense and insulating shaped refractory products, when subjected to a constant load under conditions of progressively rising temperature (or refractoriness under load), by a differential method. The test may be carried out up to a maximum temperature of 1700 °C.
