This standard specifies a method for determining the electrical conductivity of an aqueous extract. The method is based on extracting a sample of semi-finished fibrous product, paper or cardboard with boiling double-distilled or deionized water and measuring the electrical conductivity or electrical resistance of the resulting extract
