DIN EN ISO 15091:2013-04

The standard specifies a method for determining the electrical conductivity and the electrical resistance of coating materials. The conductivity is usually measured for water-borne paints and varnishes, including electrodeposition coating materials, and the resistance is usually measured for solvent-borne paints and varnishes. If required, the resistivity of the coating material is calculated from either of these measurements. The method is applicable to products having a conductivity of less than 5 µS/cm, corresponding to a resistivity of greater than 200 kΩ cm. The conductivity of coating materials influences their processibility in the presence of an electric field. This is particularly important for electrodeposition paints and coating materials which are processed electrostatically. The committee responsible for this standard is NA 002-00-07-12 AK "Leitfähigkeit und pH-Wert" ("Electrical conductivity and ph-value") at DIN.
