Describes the methods for characterizing acetate flame which have been updated in line with internal standards in this area.

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.
