《GB/T 31413-2015色漆和清漆用漆基 脂松香的鉴定 气相色谱分析法》由TC5(全国涂料和颜料标准化技术委员会)归口,主管部门为中国石油和化学工业联合会。
本标准规定了采用毛细管柱分离松香酸的挥发性甲基酯来测定脂松香中某种松香酸含量的气相色谱方法。主要目的是用来鉴定特定种类松树的脂松香,而并非用于脂松香的定量分析。如果需要进行
定量分析,应按照 ASTM D5974中规定的内标法进行测定。
Scope
This standard specifies a gas chromatographic method for the determination of the content of certain abietic acids in gum rosin by separating volatile methyl esters of abietic acids with a capillary column. The main purpose is to identify the gum rosin of a specific species of pine, not for the quantitative analysis of gum rosin. If quantitative analysis is required, it should be determined according to the internal standard method specified in ASTM D5974.
