标准范围

本方法适用于醛含量在0.00025%（m/m）至0.00125%（m/m）范围内的产品。该原理基于试验部分中的醛与希夫试剂的反应。将获得的颜色与含有已知量乙醛的标准比色溶液的颜色进行目视比较。-国际标准ISO 1388/1至ISO 1377/12取消并取代了ISO建议R 1388-1970，这些标准构成了技术修订版。

The method is applicable to products having aldehyde contents in the range 0.00025 % (m/m) to 0.00125 % (m/m). The principle is based on the reaction of the aldehydes present in a test portion with Schiff reagent. Visual comparison of the colour obtained with the colours of standard colorimetric solutions containing known quantities of acetaldehyde. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which they constitute a technical revision.
