Plastics. Polyols for use in the production of polyurethane. Determination of water content1 Scope This International Standard specifies methods used to measure the water content of polyols employed as polyurethane raw materials. Method A is a manual amperometric method which has been included to better define the principles of the Karl Fischer measurement. Amperometric methods are applicable to a wide range of polyols, including those which have enough colour to obscure a visual end point. Method B includes an automated amperometric
