ActiveRefractory products and materials—Spectrometric determination of chromium (Ⅵ)in chrome refractories
分光法测定 含铬耐火材料中六价铬分析方法
Application Summary AI generated
This standard specifies a spectrometric method for determining the concentration of hexavalent chromium (Cr(VI)) in chrome-containing refractory products and materials. It is applied in the quality control and environmental safety assessment of refractories used in high-temperature industrial furnaces, such as those in the steel, cement, and glass industries, to ensure compliance with toxicity regulations. The method is particularly relevant for testing recycled or spent chrome refractories to monitor hazardous Cr(VI) levels before disposal or reuse.
