顏料物性試驗(yàn)方法 Method of testing the Property of Pigments
1.耐光性試驗(yàn)  Teshing of Light Fastness
取各色別之試片裁剪成適當(dāng)之長(zhǎng)寬，放置于Fade-O-Meter中照射，區(qū)分3-400小時(shí)取出，其結(jié)果對(duì)照
 Blue Scale 1-To-8標(biāo)準(zhǔn)色卡之級(jí)數(shù)判定耐光程度優(yōu)劣，8級(jí)（不變色），1級(jí)***差（嚴(yán)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(yàn)  Testing of Heat Resistance
取各色別之試片裁剪成適當(dāng)之長(zhǎng)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(yàn)，觀察其變色（褪色）程度。5級(jí)（不變色），1級(jí)***差（嚴(yán)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(yàn)  Testing for Acids or Alkalis Resistance
去各色別之試片裁剪成適當(dāng)之長(zhǎng)寬，將試片浸泡于5%鹽酸或10%氫氧化鈉中，24小時(shí)后取出，觀察
其變色程度，5級(jí)（不變色），1級(jí)***差（嚴(yán)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(yàn)分級(jí)  Scale for Assessment of Physical Property of Pigment
1.耐光性Light Fastness
耐光性堅(jiān)牢度分為8級(jí)，8級(jí)代表耐光性（不變色），1級(jí)代表耐光性***差（嚴(yán)重變色）。
Light Fastness is assessed on 1 to 8 grade,grade 8 is the Exellent,grade 1 is very poor.
