DEVELOPMENT OF A TEST METHOD FOR HIDING POWER

THE PRESENT ASTM METHOD D 1738 FOR MEASUREMENT OF HIDING POWER OF NONCHROMATIC PAINTS WAS IMPROVED AND APPLIED TO THE MEASUREMENT OF CHROMATIC PAINTS. THE METHOD WAS FOUND BY FIVE COOPERATING LABORATORIES TO BE NOT ONLY REPRODUCIBLE BUT CAPABLE OF MEASURING VARIATIONS IN HIDING POWER WITH FILM THICKNESS, WHEN THIS OCCURS, WHICH IS NOT POSSIBLE BY OTHER METHODS. HIDING POWER IS THE FINAL RESULT OF A NUMBER OF DIFFERENT MEASUREMENTS ALL OF WHICH MUST BE MEASURED REPRODUCIBLY. THE METHOD IS ALSO APPLICABLE TO NONCHROMATIC PAINTS AS WELL AS THE TESTED CHROMATIC PAINTS. IT SIMULTANEOUSLY YIELDS AN EVALUATION OF THE SCATTERING COEFFICIENT OF THE PAINT. /AUTHOR/
