WebThis document specifies methods for determining the hiding power given by paint coats of white or light colours of tristimulus values Y and Y10 greater than 25, applied to a black and white chart, or to a colourless transparent foil. In the latter case the tristimulus values Y and Y10 are measured over black and white panels. canales sin voltaje

Webthe constant opacity of each unit of thickness in the form of a decimal fraction of unity. Light passing through no unit of thickness: = a LO = a Light passing through one unit of thickness: L, = a-Pa = a (1-P) Light passing through two units of thickness: L, = (a-Pa)- (a-Pa)P = a (1-P)' Light passing through three units of thickness : L, = L, = Webcause air bubbles and a non-uniform film, which would change apparent hiding power. 3.
