整个程序包括四个部分:测定有色颜料分散体的制备条件，以及测定有色颜料与白色颜料的比例；在自动研磨机上在规定条件下制备有色颜料的分散体；以已知比例将有色颜料和白色颜料的分散液与白色颜料膏混合；将所得还原膏的强度和底色与在相同条件下由商定的参考颜料和相同的白色颜料膏制成的类似膏的强度和底色进行比较。-第二版取消并取代第一版ISO 787/16-1973。

The complete procedure consists of four parts: determination of the conditions for the preparation of the dispersion of the coloured pigment, and determination of the ratio of the coloured pigment to white pigment; preparation of the dispersion of the coloured pigment under defined conditions on an automatic muller; mixing the dispersions of coloured pigment and white pigment in a known ratio with a white pigment paste; the strength and undertone of the resulting reduction paste are compared with those of a similar paste made under the same conditions from the agreed reference pigment and the same white pigment paste. - This second edition cancels and replaces the first edition ISO 787/16-1973.
