ASTM E815

Calcium Fluoride in Fluorspar by EDTA Complexometric Titrimetry

Applicability: ASTM E815 is the standard test method for determining the calcium fluoride (CaF₂) content in fluorspar by EDTA complexometric titrimetry. It is a vital analytical standard for quality control and compliance, ensuring materials meet compositional specifications for specific industrial applications.

Purpose: The purpose of ASTM E815 is to establish a standardized test method for accurately measuring the concentration of calcium fluoride (CaF₂) in fluorspar. It relies on EDTA (ethylenediaminetetraacetic acid) complexometric titration to determine exact purity.
