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 standard defines nine classes of air cleanliness:
Use the EnPIs from your ISO 14644-6 PDF to create a rolling 12-month energy baseline. Document all changes in your Quality Management System (QMS). For ISO 50001 (Energy Management) certified facilities, ISO 14644-6 integrates perfectly with the Plan-Do-Check-Act cycle. iso 146446 pdf
Operational best practices for staff behavior, gowning protocols, and daily upkeep.
To ensure you are using the most current, non-pirated, and accurate documentation, you should acquire the standards directly from accredited distributors. The standard was first published in 1999 and
Airflow that moves in a single direction with uniform velocity.
The standard is not just a technical document; it is a critical tool for risk management, quality assurance, and operational excellence. Crucially, ISO 14446 does not just stop at measurement
If your work involves the formulation of paints, coatings, or adhesives, ISO 14446 is the standard you are likely searching for. Officially titled "Binders for paints and varnishes — Determination of the viscosity of industrial cellulose nitrate solutions and classification of such solutions," this document is a critical technical specification for the industry.
