Description:
Specifies a test method for determinig the number of insoluble and visible particles including all impurties and foreign particles in cellulose acetate. A test portion is dissolved in a mixture of dichloromethane, methanol and dimethylphthalate. Counting of all visible particles with a diameter greater than 0,15 mm in a square area with a side length of 25 mm.
