标准摘要
[中文适用范围]： 本国际标准规定了采用毛细管气相色谱分离这些酸的挥发性甲酯来测定松香中某些松香酸含量的气相色谱方法。 其主要目的是鉴定特定松树品种中的松香。 它不是为松香的定量分析而设计的。 如果需要进行此类分析，则应使用 ASTM D 5974 中规定的内标技术。 [外文原描述]： ISO 19334:2010 specifies a gas-chromatographic method for determining the amounts of certain rosin acids in gum rosin using capillary gas-chromatographic separation of the volatile methyl esters of these acids. It is intended primarily to permit the identification of gum rosin from specific species of pine trees. It is not designed for the quantitative analysis of gum rosin. If such analyses are required, the internal-standard technique specified in ASTM D 5974 should be used.
英文名称Binders for paints and varnishes — Gum rosin — Gas-chromatographic analysis
