This standard specifies test methods to determine the presence of water in insulating liquids at concentrations generally below 200 ppm. 2 Annex A2 lists some modified solvent systems that allow the use of these methods to perform the volumetric analysis of some high viscosity oils and also silicones. 3 Values are given in metric units. 4 The materials, operations and equipment used in the application of the standard may present risks. However, this standard does not intend to point out all the industrial safety problems related to its application. The user of the standard has the responsibility of establishing appropriate industrial safety and occupational health conditions and also applying current legislation in this regard. Some recommendations are established in Annex A3, sections 1.1 and 4.1.
