Abstract / scope

The principle of the method specified is dispersing the test pigment and an agreed reference pigment in a particular test medium (mixture of an alkyd resin and fumed silica), preparing specimens on suitable substrates from the dispersions, measuring the tristimulus values of the specimens as described in ISO 7724-2, calculating the appropriate colour characteristics as described in ISO 7724-3.
