Cellulose

Cellulose nanomaterials standards are published by CSA and ISO. Both standards from CSA cover test methods for characterization and blank detail specification respectively, and both are available as a package in CSA Z5100/Z5200 Package-2017. ISO standards cover technical terms and characterization of cellulose nanocrystals. Cellulose is a valuable material in the nanotechnology field and these standards can protect investments in its synthesis and application.

CSA Z5100/Z5200 Package-2017

Z5100/Z5200 PACKAGE - Consists of Z5100-17, Cellulose nanomaterials - Test methods for characterization and Z5200-17, Cellulose nanomaterials - Blank detail specification

CSA Z5100-2017

Z5100-17 - Cellulose nanomaterials - Test methods for characterization

This is the second edition of CSA Z5100, Cellulose nanomaterials - Test methods for characterization. It supersedes the first edition, published in 2014. The major differences between this edition and the previous edition include: a) addition of a new test method for CMF content (consistency); b) addition of more information on recommended test methods for degree of crystallinity, colour and ISO brightness, and morphology; c) updated test methods for viscosity and rheological properties, total sulfur content, sulfate half- ester content, carboxylate content, thermal stability, and dispersibility in aqueous media; and d) alignment with new CSA standard Z5200. This Standard provides a consolidated set of test methods to characterize base cellulose nanomaterials. This Standard is the first in a series on cellulose nanomaterials intended to serve as a foundation for the development of both Canadian and international standards to facilitate introduction of cellulose nanomaterials into global markets. This is a companion standard to CSA Z5200.

CSA Z5200-2017

Z5200-17 - Cellulose nanomaterials - Blank detail specification

This is the first edition of CSA Z5200, Cellulose nanomaterials - Blank detail specification. This Standard specifies how to report measurable properties and characteristics of cellulose nanomaterials in commercial applications, for use between vendor and user. Since the quality of an end product depends, among other things, on the properties and characteristics of the nanomaterial, it is necessary to define a material specification for intended applications. This Standard is the second in a series on cellulose nanomaterials intended to serve as a foundation for the development of both Canadian and international standards to facilitate introduction of cellulose nanomaterials into global markets. This is a companion standard to CSA Z5100.

ISO/TR 19716:2016

Nanotechnologies - Characterization of cellulose nanocrystals

ISO/TR 19716:2016 reviews commonly used methods for the characterization of cellulose nanocrystals (CNCs), including sample preparation, measurement methods and data analysis. Selected measurands for characterization of CNCs for commercial production and applications are covered. These include CNC composition, morphology and surface characteristics.

ISO/TS 20477:2017

Nanotechnologies - Standard terms and their definition for cellulose nanomaterial

ISO/TS 20477:2017 defines terms and definitions for different types of cellulose nanomaterials including secondary components found in cellulose nanomaterials due to their manufacturing processes. The document also gives information on cellulose micromaterials in Annex A. Where necessary, terms from the ISO/IEC 80004 vocabulary series are included in this document. Terms in this document are applicable to all types of cellulose nanomaterials regardless of production methods and their origin (plants, animals, algae or bacteria).
