Binders for paints and varnishes - Determination of the viscosity of industrial cellulose nitrate solutions and classification of such solutions (ISO 14446:1999)
This International Standard specifies a method of determining the viscosity of industrial cellulose nitrate, usually
referred to as nitrocellulose, the nitrogen content of which can vary between 10,7 % by mass and 12,6 % by mass,
depending on the type.
It also gives a classification system for industrial cellulose nitrate solutions (see annex A) which is based on
viscosity measurements made using the method. The use of a standard procedure results in "standard" types and
avoids classification differences which could be caused by the fact that there are many ways of determining
viscosity and a wide variety of solvents available.
