ICS Code (Insulating oils): | 29.040.10 |
ICS Code (29.035.40): | 29.035.40 |
ICS Code (Paper and board insulating materials): | 29.035.10 |
ICS Code (Other standards related to electricity and magnetism): | 17.220.99 |
scope:
This International Standard describes methods for the determination of water in insulating liquids and in oil-impregnated cellulosic insulation with coulometrically generated Karl Fischer reagent.
The method in clause 2 is applicable to water concentrations above 2 mg/kg in liquids having viscosity 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 the preferred method for insulating liquids of viscosity higher than 100 mm2/s.
Clause 4 describes methods for the determination of water content in oil-impregnated paper and pressboard over the range 0,1 % to 20 % by mass.
