Standards & Standards Development Activities

International standards have the potential to remove trade barriers, harmonize research and development activities, and contribute to development of regulations by national and international bodies. As government, academic and industrial research and development organizations endeavor to understand and develop cellulose nanomaterial-based products for multiple industrial sectors, the need for international standards for cellulose nanomaterials is evident and growing. The Canadian Standards Association (CSA) Group and the International Organization for Standardization (ISO) are taking the lead in standards development efforts. ISO standard development activities are carried out within two technical committees: TC 6 - Paper, board and pulps (whose scope includes cellulose nanomaterials), and TC 229 - Nanotechnologies.   

Standards development has progressed in the following areas: Terminology, Measurement and Characterization, EHS, and Material Specification.

Published Standards

ISO/TC 229 - TS 20477:2017 : Standard terms and their definition for cellulose nanomaterial

ISO/TC 229 - TR 19716:2016 : Characterization of cellulose nanocrystals

ISO/TC 229 - TR 12885:2008 and CSA Z12885-12 (R2017) : Health and safety practices in occupational settings relevant to nanotechnologies

CSA Z5100-17 : Cellulose nanomaterials - Test methods for characterization

CSA Z5200-17 : Cellulose nanomaterials - Blank detail specification

Road Maps

2011 Roadmap for the Development of International Standards For Nanocellulose:

This Roadmap is a result of a 2011 International Standards Workshop held on June 9, 2011 in Washington, D.C. The Roadmap was written by a team of global experts following in-depth break-out sessions conducted at the workshop.
