本试验方法适用于蒸发后干燥残留物大于或等于10 mg/kg？0.001%（m/m）ü的产品。该原理包括在水浴上蒸发试验部分，并在110°C 2 K的烘箱中将残留物（如有）干燥至恒定质量。取消并取代ISO建议R 759-1968，该建议构成了技术修订版。

The method of test is applicable to products having dry residues after evaporation greater than or equal to 10 mg/kg？0.001 % (m/m)ü. The principle consists in evaporation of a test portion on a water bath, and drying the residue, if any, to a constant mass in an oven at 110 °C 2 K. - Cancels and replaces ISO Recommendation R 759-1968 of which it constitutes a technical revision.
