Sets out methods for the sampling, sample preparation, and analysis of chrome-bearing materials.

Scope

This Standard sets out methods for the sampling, sample preparation, and analysis of chrome-bearing refractories and refractory materials. Procedures are described for the determination ofā€”
(a) the loss on ignition*; and
(b) the chemical composition*, viz the amount of silicon, chromium, titanium, iron, aluminium, manganese, calcium, magnesium, sodium, potassium and lithium present in chrome-bearing materials, expressed as the oxides of these elements.
NOTE: Appendix C provides an overview of these test procedures in flowchart form.
This Standard applies to chrome-bearing materials represented by those defined in Clause 1.3, whose composition is typified by Table 1.1. It may be applicable to materials which fall outside these ranges, but if used for such cases, it is necessary to exercise caution when interpreting the results as it cannot be assumed the limits cited in Clause 1.5 apply.
