Plastics - Unplasticized cellulose acetate - Determination of acetic acid yield

inactive, Most Current
Organization: NEN
Publication Date: 1 December 1975
Status: inactive
ICS Code (Thermosetting materials): 83.080.10
scope:

This International Standard specifies a methode for the determination of acetic acid yield of unplasticized cellulose acetate. These methods are intended for cellulose acetate without plasticizers and free of additives, fillers, dyes or other materials which affect the tests. When they are present, they must be separated by a method agreed between the contracting parties. The methods are applicable to cellulose acetate having any acetic acid yield. Method A is applicable to cellulose acetate in the form of finely divided powder. Method B is applicable to cellulose acetate in any physical form (powder, grains, flakes, etc.)
