This International Standard specifies a method for the determination of the tinting strength of carbon black relative to an industry tint reference black.
The method is based on the use of three different commercial instruments. Other instruments may be used but they shall have at least equivalent perform-ance.
NOTE 1 Details of the manufacturers of the Erichsen Tint Tester are given in the relevant clause of this International Standard. The Densichron reflectometer and the Meeco Colormaster are no longer available commercially, but the methods are included for the benefit of users of these in-struments.
