BS 1902-9.2:1987

This standard BS 1902-9.2:1987 Methods of testing refractory materials. Chemical analysis by instrumental methods is classified in these ICS categories:

• 81.080 Refractories

This Section of BS 1902-9 describes a method for analysing silica refractories using X-ray fluorescence.

The method is intended for materials containing more than 92 % of silica (SiO₂) on the ignited basis. The ranges of content of constituents are given in Table 1 except for those used in glass manufacture which are given in Appendix C.

Appendix C gives modifications to this method which are required where it is to be used for the analysis of silica sands used in glass manufacture.
