This document specifies a method for determining the hiding power (spreading rate necessary to give a hiding power of 98 %) of white or light-coloured paints. It is applicable to paint films having the tri-stimulus value of Y<\/i> ? 70 and hiding power > 80 %. It is not applicable to fluorescent or metallic paints.<\/p>\n
