CAN/CSA-Z5200-17

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.
