Methods of testing cellulose acetate flake
This standard describes methods of test for the following cellulose acetate flake properties:
moisture content;
ash content;
acetic acid yield;
bulk density;
particle size distribution;
free acidity;
viscosity ratio of a 5 g/L solution at 25 °C;
viscosity at a concentration of 60 g/L;
viscosity at 25 % concentration at 25 °C;
insoluble particles;
original light absorption and change of light absorption after heating of plasticized cellulose acetate;
the reduction in viscosity ratio on moulding.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
