BS EN ISO 10058-2:2008

This standard BS EN ISO 10058-2:2008 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 traditional (“wet process”) methods for the chemical analysis of magnesite and dolomite refractory products and raw materials.

It is applicable to components within the ranges of determination given in Table 1.

Table 1

Range of determination (percentage by mass)

Component	Range	Component	Range
SiO2	0,1 to 10	MgO	30 to 99,9
Al2O3	0,05 to 10	Na2O	0,01 to 1
Fe2O3	0,01 to 10	K2O	0,01 to 1
TiO2	0,01 to 1	Cr2O3	0,01 to 3
MnO	0,01 to 1	ZrO2	0,01 to 1
CaO	0,01 to 60	P2O5	0,01 to 5
LOI	0,01 to 60	—	—
NOTE These values are after the loss on ignition (LOI) has been taken into account.
