EN ISO 105-J03 Textile - Color Fastness Tests - Part J03: Test for Calculation of Color Differences

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 105-J03 testing. EN ISO 105-J03 provides a method for calculating the color difference between two samples of the same material, measured under the same conditions.

It allows specifying a maximum value (tolerance) that depends only on the closeness of the match required for a particular end use, not the color involved or the nature of the color difference. The method also provides a means of determining the ratio of differences in aperture to chroma and tone.

The color space has been modified to increase visual uniformity when calculating the color difference between two samples. Modifications to CIELAB by the CMC equation provide a numerical value that describes the color difference between a sample and a reference in a more uniform color space. This allows a single-digit tolerance ("acceptability tolerance" or "pass/fail tolerance") to be used to judge the acceptability of a color match where the tolerance is independent of the color of the reference.
