Plastics. Polyols for use in the production of polyurethane. Determination of water content Ingestion-build-189776 PD CLC IEC/TR 62453-52-31 specifies1 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
