CHEMOTRONIC III

55

Standard test method for cloud point 

measurements

Apparatus:

1)

CHEMOTRONIC automatic cloud point tester

2)

Digital balance min. range 0..100 grams with 0.01 
grams resolution

Preparation:

A 10% solution of the resin under test oil with the 
high-quality grade mineral test oil must be prepared 
as follow:

1)

Place the glass test tube with the magnet stirrer rod 
into the test tube holder and place the holder on the 
balance.

2)

Zero the balance.

3)

Weigh in 2.0 grams of resin.

4)

Zero the balance.

5)

Weigh in 18.0 grams of test oil.
