Scope

WARNING: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This standard specifies the principle of the method, reagents, devices, samples, analysis steps, calculation of analysis results and tolerances for the determination of carbonate content in fluorite. This standard includes two methods: EDTA titration, measuring range (mass fraction expressed as calcium carbonate) 0.10% to 3.00%; acid-base titration method, measuring range (mass fraction expressed as calcium carbonate) WCaCO₃ ≥0.040%. This standard applies to the determination of carbonate content in fluorite.
