Projekta Nr.ISO 105-J03:2009
Nosaukums<p>ISO 105-J03:2009 provides a method of calculating the colour difference between two specimens of the same material, measured under the same conditions, such that the numerical value ∆<i>E</i><sub>cmc</sub>(<i>l</i>:<i>c</i>) for the total colour difference quantifies the extent to which the two specimens do not match. It permits the specification of a maximum value (tolerance) which depends only on the closeness of match required for a given end-use and not on the colour involved, nor on the nature of the colour difference. The method also provides a means for establishing the ratio of differences in lightness to chroma and to hue.</p>
