This standard specifies a method of determining the viscosity of industrial cellulose nitrate solutions, 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 describes a classification system for industrial cellulose nitrate (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. The Committee responsible for this standard is NA 002-00-02 AA "Lackrohstoffe" ("Raw materials for paints and varnishes") at DIN.
