标准范围

规定方法的原理是将主流烟雾中的烟雾冷凝液溶解在溶剂中，并用标准卡尔·费希尔试剂滴定，测定一份溶液的含水量。吸烟和主流烟雾的收集通常按照ISO 4387进行。然而，该方法也适用于通过非标准吸烟获得的烟雾冷凝液中水分的测定。

The principle of the method specified is dissolving the smoke condensate from the mainstream smoke in a solvent and determination of the water content of an aliquot of the solution by titration with standardized Karl Fischer reagent. The smoking of cigarettes and collection of mainstream smoke are normally carried out in accordance with ISO 4387. However, the method is also applicable to the determination of water in smoke condensates obtained by non-standard smoking.
