This part of ISO 20565 specifies traditional (“wet process”) methods for the chemical analysis of chrome-bearing 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.
