1 Scope

This part of ISO 20565 specifies traditional (“wet process”) methods for the chemical analysis of chromebearing refractory products and raw materials.

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

Table 1 — Range of determination (% by mass)

Component	Range
SiO₂	0,5 to 10
Al₂O₃	2 to 30
Fe₂O₃	0,5 to 25
TiO₂	0,01 to 1
MnO	0,01 to 1
CaO	0,01 to 3
MgO	15 to 85
Na₂O	0,01 to 1
K₂O	0,01 to 1
Cr₂O₃	2 to 60
ZrO₂	0,01 to 0,5
P₂O₅	0,01 to 5
LOI	-0,5 to 5
NOTE These values are after the loss on ignition (LOI) has been taken into account.
