| 颜料物性试验方法 Method of testing the Property of Pigments | ||||||||
| 1.耐光性试验 Teshing of Light Fastness | ||||||||
| 取各色别之试片裁剪成适当之长宽，放置于Fade-O-Meter中照射，区分3-400小时取出，其结果对照 | ||||||||
| Blue Scale 1-To-8标准色卡之级数判定耐光程度优劣，8级（不变色），1级***差（严重变色）。 | ||||||||
| Cutting various pieces of color pattern sheets to suitable sizes,then put them into the Fade- | ||||||||
| O-Meter for light exposure,ａnd to divide the time of exposure to be in the range of 3-400 ho- | ||||||||
| urs. Afterward,take out the test pattern sheets to assess their degrees of color fading and dis- | ||||||||
| coloration against a standard Blue Scale which is assigned to value form 1 to 8. Grade 8 is the | ||||||||
| excellent(color will not be changed),grade 1 is very poor (color is shanged severly). | ||||||||
| 2.耐热性试验 Testing of Heat Resistance | ||||||||
| 取各色别之试片裁剪成适当之长宽，8块放置于烘箱中，以180±2℃每隔10分钟取出1块，至8块取完 | ||||||||
| 为止，作老化试验，观察其变色（褪色）程度。5级（不变色），1级***差（严重变色）。 | ||||||||
| Cutting various pieces of color pattern sheets to suitable sizes,Take 8 pieces and put them into | ||||||||
| an oven under a condition of 180±2℃ for testing.Take out each piece every 10 minute,ａnd to | ||||||||
| inspect their degree of color changing (degree of color fading).Grade 5 is the excellent and | ||||||||
| grade 1 is the worst. | ||||||||
| 3.耐酸碱性试验 Testing for Acids or Alkalis Resistance | ||||||||
| 去各色别之试片裁剪成适当之长宽，将试片浸泡于5%盐酸或10%氢氧化钠中，24小时后取出，观察 | ||||||||
| 其变色程度，5级（不变色），1级***差（严重变色）。 | ||||||||
| Cutting various pieces of color pattern sheets to suitable sizes,Take desired piece dip in into | ||||||||
| the bath of 5% HCl or 10% NaOH for 24 hours,then take them out to assess their degree of | ||||||||
| color fading. On a comparison scale,Grade 5 is the excell ent and grade 1 is the worst. | ||||||||
| 颜料物性检验分级 Scale for Assessment of Physical Property of Pigment | ||||||||
| 1.耐光性Light Fastness | ||||||||
| 耐光性坚牢度分为8级，8级代表耐光性（不变色），1级代表耐光性***差（严重变色）。 | ||||||||
| Light Fastness is assessed on 1 to 8 grade,grade 8 is the Exellent,grade 1 is very poor. | ||||||||
| Blue scale for Light Fastness | ||||||||
| Blue Scale | Fade-O-Meter Full Exposure | |||||||
| 8级：特优 Outstanding | 400Hours | |||||||
| 7级：极优 Exellent | 200Hours | |||||||
| 6级：优 Very Good | 100Hours | |||||||
| 5级：良 Good | 50Hours | |||||||
| 4级：中 Fairly Good | 25Hours | |||||||
| 3级：可 Moderate | 12Hours | |||||||
| 2级：差 Poor | 6Hours | |||||||
| 1级：极差 Very Poor | 3Hours | |||||||
