Scope

This Standard sets out methods for the sampling, preparation of samples and analysis of dolomite and magnesite refractories and refractory materials. Procedures are described for determining -
(a) the loss on ignition;
(b) the chemical composition, i.e. the amount of silicon, iron, titanium, manganese, chromium, aluminium, magnesium, calcium, sodium, potassium and lithium present in magnesites and dolomites, expressed as the oxides of these elements; and
(c) the boron content of magnesites expressed as boron (III) oxide.
This Standard applies to dolomites and magnesites whose composition is typified by Table 1. It may be applicable to materials which fall outside these ranges subject to agreement between interested parties.
