CAN/CSA-Z5200-17 (R2022)

Description

Preface 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. Cellulose nanomaterials extracted from cellulose sources, such as wood pulps, are biodegradable, sustainable, and retain the non-toxicity of cellulose. These materials have numerous potential applications in areas such as composite materials, optical films and devices, catalysts, and pharmaceuticals. This Standard was reviewed by the Technical Committee on Cellulose Nanomaterials, under the jurisdiction of the Strategic Steering Committee on Health Care Technology and Systems and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard provides guidance and a blank detail specification for cellulose nanomaterials (CNMs), for determining and listing essential properties and characteristics with reference to corresponding test methods in CSA Z5100 and other standards. CNMs in this Standard include cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs), and cellulose microfibrils (CMFs). 1.2 Numeric values for properties and characteristics in the blank detail specification are intentionally left blank and should be determined by agreement between the customer and the cellulose nanomaterial supplier. Properties and characteristics deemed by the customer and supplier as not relevant to a specific cellulose nanomaterial or application may be classified as “not applicable” or “not specified”. 1.3 This Standard does not include detail specifications for cellulose nanomaterial-based nano-enhanced or nano-enabled products. 1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.5 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
