本文件规定了用气相色谱法测定主流烟气中总颗粒物中水的方法。吸烟和主流烟雾的收集通常按照ISO 4387进行。然而，本文件的方法也适用于非标准吸烟产生的主流烟雾中总颗粒物中水的测定。 注:在无法使用气相色谱法的国家，使用卡尔·费舍尔法（见ISO 10362-2）测定主流烟气中总颗粒物中的水分。在这种情况下，使用从主流烟气中获得的总颗粒物中水的值，并在结果表达式中添加注释。交叉引用:ISO 4387ISO 3696:1987ISO 3308ISO 10362-2ISO 10315ISO 3402ISO 8243购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies a method for the gas-chromatographic determination of water in total particulate matter from the mainstream smoke. The smoking of cigarettes and collection of mainstream smoke are normally carried out in accordance with ISO 4387. However, the method of this document is also applicable to the determination of water in total particulate matter from the mainstream smoke obtained by non-standard smoking. NOTE In countries not in a position to use the gas-chromatographic method, the determination of water in total particulate matter from the mainstream smoke is performed using the Karl Fischer method (see ISO 10362-2). In such cases, values obtained for water in total particulate matter from the mainstream smoke are used with the addition of a note made in the expression of the results.Cross References:ISO 4387ISO 3696:1987ISO 3308ISO 10362-2ISO 10315ISO 3402ISO 8243All current amendments available at time of purchase are included with the purchase of this document.
