- Scope
- This international Standard specifies two methods for the determination of the acetic acid yield of unplasticized cellulose acetate. These methods are intended for cellulose acetate without plasticizers and free of additives, 和lers,， dyes or other materials which affect the tests. When such mnaterials are present, they shall first be removed by a _pmethod agreed between the contracting parties， The methods are applcable to cellulose acetate hav- ing any acetic acid yiejd. Method Alis applicable to cellulose acetate in the form of finely divided powder. Method B is applicable to cellulcse acetate in any physical form (powder grains， flakes，etc .).
