When calibrating the concentration of the standard titration solution according to the "GB / T601-2002 Preparation of Chemical Reagent Standard Titration Solution", two people are required to carry out the experiment, each doing four parallels. The relative value of the critical range [CrR95 (4)] is 0.15%. The relative value of the two people's total eight parallel determination results should not be greater than the relative value of the repeatable critical range [CrR95 (8)] of 0.18%.
