Abstract / scope
ISO 5435:2008 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 five different commercial instruments. Other instruments may be used if the test results for the standard reference blacks are within the control limits given in ASTM D 4821.
NOTE The Densichron reflectometer and the Meeco Colormaster are no longer commercially available, but the methods have been included for the benefit of those who still use these instruments.
