标准简介
This Standard is one of a series of standard dealing with the sampling and testing of paints, varnishes and related products. It specifies methods for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of tristimulus value Y greater than 25, applied at a spreading rate of 20 m*2/l to an agreed black and white chart or to colourless transparent polyester foil, in the latter case the tristimulus valus Y being measured subsequently over agreed black and white glass panels.
