The ISO 14680-1:2000 standard specifies a technique for determining the pigment content in Paints and varnishes using centrifugation. This method separates solids in Coatings by centrifugal settling in order to determine the pigment content. This method is particularly suitable for checking coatings containing carbon black, very fine silica or titanium dioxide, but may encounter difficulties for latex paints, etc. The standard provides detailed operating procedures and precautions to ensure the accuracy and Reliability of the measurement results.
