ISO 758:1976 工业用液态化学制品.在20℃时的浓度测定

标准编号：ISO 758:1976

中文名称：工业用液态化学制品.在20℃时的浓度测定

英文名称：Liquid chemical products for industrial use — Determination of density at 20 degrees C

发布日期：1976-11

标准范围

规定的参考方法的原理包括在20°C下测定比重瓶中所含物质体积的质量，以及通过在20°C下测量足够体积的水的质量来测定比重瓶的容量。通过物质质量除以比重瓶容量来计算密度。-取代ISO建议R 758-1968。

The principle of the specified method of reference consists in the determination of the mass of a volume of the substance at 20 °C which is contained in a pyknometer, and the determination of the capacity of pyknometer by measuring the mass of an adequate volume of water at 20 °C. Calculation of the density by division of the mass of substance by the capacity of pyknometer. - Replaces ISO Recommendation R 758-1968.
