  • Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = \u2018Poor\u2019 and 8 = \u2018Excellent\u2019.<\/li>\n
  • Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.<\/li>\n
  • Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.<\/li>\n
  • Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
    \nwhere 1 = \u2018Heavy bleeding\u2019 and 5 = \u2018No bleeding”<\/li>\n<\/ul>\n
