本国际标准规定了石油产品中水含量高达25%的测定方法， 通过蒸馏法从这些材料中提取的沥青、焦油和产品，不包括乳液。这个 表3列出了本试验方法制定过程中考虑的特定产品。 本国际标准可用于测定超过25%的水含量。然而，没有精确的数据 已在高于25%的水平上确定。挥发性水溶性物质（如果存在）被测量为水。 注1:了解石油产品的含水量对石油产品的精炼、购买、销售和转让至关重要 产品。 注2:通过该方法确定的水量可用于校正监护转移中涉及的水量 当然是产品。

This International Standard specifies a method for determination of water up to 25 % in petroleum products, bitumens, tars and products derived from these materials, excluding emulsions, by the distillation method. The specific products considered during the development of this test method are listed in Table 3. This International Standard may be used to determine water content in excess of 25 %. However, no precision data has been determined at levels greater than 25 %. Volatile water-soluble material, if present, is measured as water. NOTE 1 A knowledge of the water content of petroleum products is important in the refining, purchase, sale and transfer of products. NOTE 2 The amount of water determined by this method can be used to correct the volume involved in the custody transfer of product.
