Methods of test for paints - Determination of colour and colour difference: calculation Ingestion-build-251241 voltage and current tolerances from1 Scope and field of application This part of ISO 7724 describes a method for the quantitative colorimetric evaluation of small colour differences between paint films. NOTE There are numerous formulae for calculating a colour difference from the colour co ordinates of two specimens. For various reasons the results given by such formulae, including the one defined here, do not in all cases agree satisfactorily with visual perception nor are they likely
