顏料物性試驗方法 Method of testing the Property of Pigments
1.耐光性試驗  Teshing of Light Fastness
取各色別之試片裁剪成適當之長寬,放置于Fade-O-Meter中照射,區(qū)分3-400小時取出,其結果對照
 Blue Scale 1-To-8標準色卡之級數(shù)判定耐光程度優(yōu)劣,8級(不變色),1級***差(嚴重變色)。
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.耐熱性試驗  Testing of Heat Resistance
取各色別之試片裁剪成適當之長寬,8塊放置于烘箱中,以180±2℃每隔10分鐘取出1塊,至8塊取完
為止,作老化試驗,觀察其變色(褪色)程度。5級(不變色),1級***差(嚴重變色)。
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.耐酸堿性試驗  Testing for Acids or Alkalis Resistance
去各色別之試片裁剪成適當之長寬,將試片浸泡于5%鹽酸或10%氫氧化鈉中,24小時后取出,觀察
其變色程度,5級(不變色),1級***差(嚴重變色)。
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.

顏料物性檢驗分級  Scale for Assessment of Physical Property of Pigment
1.耐光性Light Fastness
耐光性堅牢度分為8級,8級代表耐光性(不變色),1級代表耐光性***差(嚴重變色)。
Light Fastness is assessed on 1 to 8 grade,grade 8 is the Exellent,grade 1 is very poor.
