ISO 11349:2010定义了使用重量分析法测定水中低挥发性亲脂性物质的方法。 该方法适用于所有类型的水，并允许测定悬浮、乳化或溶解的低挥发性亲脂性物质，其浓度约为10 mg/l至500 mg/l。高于该值时，适当稀释试验部分。 该方法不适用于具有单独油层的水。

ISO 11349:2010 defines a method for the determination of lipophilic substances of low volatility in water using gravimetry. The method is applicable to all kinds of water and allows the determination of low？volatility lipophilic substances which are suspended, emulsified, or dissolved, in concentrations of about 10 mg/l to 500 mg/l. Above this value, the test portion is diluted appropriately. The method is not applicable to water with a separate oil layer.
