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.
