The GB/T 6730.88-2024 standard specifies a method for the determination of chlorine content in iron ore using wavelength dispersion X-ray fluorescence spectrometry. It is suitable for the determination of chlorine content in natural iron ore, iron concentrate, sinter and pellet, with a determination range of 0.010% to 1.20% (mass fraction). The standard requires users to have practical experience in formal laboratory work and warns users to take appropriate safety and health measures to ensure compliance with relevant national regulations. The cited normative documents include Precision of Measuring Method, Preparation of Iron Ore Samples and Sampling Methods to ensure the accuracy and Reliability of test results.
