Describes a gravimetric method for determining the loss on ignition and the classical and spectrophotometric methods of analysis of high alumina refractory materials for the determination of the oxides of silicon, phosphorus, aluminium, iron(III), titanium, manganese, calcium and magnesium. Sodium, potassium and lithium are determined as the oxides by flame photometry. The results are expressed as a percentage (m/m) of the original material. The typical composition of high alumina refractory materials, is included together with a statement on the repeatability of the analysis.

This standard sets out methods for the sampling, preparation of sample and analysis of high alumina refractories and high alumina refractory materials. Procedures are described for determining-(a) the loss on ignition; and(b) the chemical composition, viz the amount of silicon, phosphorus, aluminium, iron, titanium, manganese, calcium, magnesium, sodium, potassium and lithium present, expressed as the oxides of these elements.
