If you are writing a paper or studying the standard, here are the key technical changes introduced in the current version (2015) compared to the previous one: iso 146446 pdf
The standard was first published in 1999 and provides a universally recognized method for measuring the viscosity of industrial cellulose nitrate, commonly known as nitrocellulose. This substance is a key ingredient in various surface coatings and printing inks. The standard is specifically designed for solutions where the nitrogen content of the nitrocellulose varies between 10.7% and 12.6% by mass . Crucially, ISO 14446 does not just stop at measurement. It also establishes a classification system (detailed in Annex A of the document) for these solutions based on the viscosity results obtained. The primary goal is to create "standard" types, preventing discrepancies in classification that often arise from laboratories using different measurement techniques or various types of solvents. The ISO 14644 family consists of multiple parts, e
