BS EN ISO 10058-1:2008

This standard BS EN ISO 10058-1:2008 Chemical analysis of magnesite and dolomite refractory products (alternative to the X-ray fluorescence method) is classified in these ICS categories:

• 81.080 Refractories
• 73.080 Non-metalliferous minerals

This part of ISO 10058 specifies apparatus, reagents, dissolution and gravimetric silica analysis for the chemical analysis of magnesite and dolomite refractory products and raw materials.

This part of ISO 10058 is applicable to the ranges of determination given in Table 1.

ISO 10058 specifies procedures for the chemical analysis of magnesite and dolomite refractory products and raw materials within the ranges of determination given in Table 1.
