- Scope
- Specifies the standard method to be used in comparing the contrast ratios given by paint films of white or ligth colours, of refelctance factor greater than 40 %, dried at normal air temperature and applied at approximately equal wet film thickness to black and white substrates. The wet film thickness selected, approximately 50 um, corresponds to a spreading rate of approximately 20 m2/l. Because different operators using the same film coating device obtain films differing in thickness the method is not satisfactory as an absolute method for the determination of hiding power.
