The ISO 14446-1999 standard specifies a method for determining the viscosity of industrial nitrocellulose solutions and provides a classification system. The standard applies to nitrocellulose solutions with a nitrogen content in the range of 10.7% -12.6%, helping to classify products of different viscosities. The standard classification system helps to avoid classification differences due to different viscosity measurement methods and solvent types.
