This Technical Specification specifies two alternative methods for determining the resistance to thermal shock of dense shaped refractory materials by the air quenching method which proved to give the most reliable results as compared with the behaviour of the refractories placed in furnace linings. Method B can be applied to unshaped refractory materials too.
