This International Standard specifies a method for
the determination of the reduction in viscosity which
occurs when cellulose acetate is moulded. The viscosity
loss on moulding is related to the
depolymerization of cellulose acetate, which generally
increases brittleness in the moulded product.
This method is suitable for cellulose acetate which
does not contain additives, fillers, etc., which may
interfere with the determination of viscosity.
lt is suitable for cellulose acetate having an acetic
acid yield above 50 %.
