英文名称：Sodium carbonate for industrial use — Determination of total soluble alkalinity — Titrimetric method

发布日期：1976-02

标准范围

规定了测定溶解物质碱度的滴定试验方法。该程序的原理包括将供试品在水中溶解，过滤溶液，并在甲基橙存在下用盐酸标准体积溶液滴定。重新采用ISO建议R 740-1968。

Specifies a titrimetric test method for the determination of the basicity of soluted material. The principle of the procedure consists in solution of a test portion in water, filtration of the solution and titration with a standard volumetric solution of hydrochloric acid in presence of methyl orange as indicator. Repaces ISO Recommendation R 740-1968.
