Method of Testing for Physical Property
Testing of Light Fastness:
Take pieces of general color pattern sheets to put them into the Fade-o-Meter for light exposure. Afterward, take out the test pattern sheets to assess their degrees of light fastness against a standard Blue Scale which is assigned to value from 1 to 8. Level 8 is the outstanding (color will not be changed) and Level 1 is very poor (color is changed severely).
Testing for Heat Resistance:
Take pieces of general color pattern sheets and put them into an oven under a condition of 180℃ ± 2℃ for 30 min. Then take out the test pattern sheets to inspect their degree of color changing (degree of color fading). Afterward, assess the results for their degrees of heat resistance against a standard Gray Scale which is assigned to value from 1 to 5. Level 5 is the most excellent (color will not be changed) and Level 1 is the worst (color is changed severely).
Testing for Migration:
Take pieces of general color pattern sheets sandwiched in between two pieces of white color pattern sheets, and put the whole structure into an oven under a loading pressure of 3KG on the top for 80°C x 24 hours. Then take them out finally to inspect the degree of migration on the white color sheets surface against a Scale which is assigned to value from 1 to 5. Level 5 is the most excellent (no migration) and Level 1 is the worst (severe migration).
Testing for Acids or Alkalis Resistance:
Take pieces of general color pattern sheets and dip it into the bath of 5% HCI or 10% NaOH for 24 hours. Then take out the test pattern sheets to inspect their degree of color changing against a Scale which is assigned to value from 1 to 5. Level 5 is the most excellent (color will not be changed) and Level 1 is the worst (color is changed severely).
Testing for Sulfur Resistance:
Take pieces of general color pattern sheets and place them on the top of a H2S (Hydrogen Sulfur) generator. Then cover them with a flat piece of glass on top for pressing for 15 minutes. And then take out the test pattern sheets to inspect their degree of contamination against a Scale which is assigned to value from 1 to 5. Level 5 is the most excellent (was not contaminated at all) and Level 1 is the worst (was contaminated severely).

※Remark: The Scale of Fastness for comparison is very important in the proper selection of appropriate pigments for coloring processes. Conditions of processing, end-uses application fields and the required properties of the finished product should be consulted before making a final selection of the optimal pigments.
