This International Standard describes methods for the determination of water in insulatingliquids and in oil-impregnated cellulosic insulation with coulometrically generated Karl Fischerreagent.The method in clause 2 is applicable to water concentrations above 2 mg/kg in liquids havingviscosity of less than 100 mm2/s at 40 °C.The test method in clause 3, where water is extracted by means of a nitrogen stream, is thepreferred method for insulating liquids of viscosity higher than 100 mm2/s.Clause 4 describes methods for the determination of water content in oil-impregnated paperand pressboard over the range 0,1 % to 20 % by mass.
