标准摘要
[中文适用范围]： 本国际标准规定了用电位滴定法测定乙醇总酸度的方法。总酸度以每升乙醇中含有的乙酸质量表示，单位为毫克；或者以乙酸的质量分数（% m/m）表示，如果已知乙醇的密度。 注意：对于本国际标准而言，“% m/m”和“% v/v”分别代表材料的质量分数和体积分数。 [外文原描述]： ISO 17315:2014 specifies a test method for the determination of total acidity of ethanol by potentiometric titration. The total acidity is reported as acetic acid mass, in milligrams, per ethanol volume, in litres, or as mass percent of acetic acid (% m/m), if the density of ethanol is known.
