This method is a rapid EDTA complexometric method for determining calcium in lime and limestone products used in cane sugar processing. The absolute difference between two results obtained under repeatability conditions should be not greater than 0.24 g/100g CaO in the sample. The absolute difference between two results obtained under reproducibility conditions should be not greater than 0.31 g/100 g CaO in the sample.
