Nanomatériaux à base de cellulose - Méthodes d'essai pour la caractérisation

1.1
This Standard describes test methods for characterization of base cellulosic nanomaterials, specifically cellulose nanofibrils (CNFs) and cellulose nanocrystals (CNCs).

1.2
This Standard does not cover the characterization of nanostructured cellulosic materials, including cellulose microfibrils (CMF) and cellulose microcrystals (CMC).

1.3
This Standard does not cover cellulosic nanomaterial enhanced or enabled products.

Note: This Standard may be expanded in future editions as cellulosic nanomaterial-enhanced and enabled products move towards commercialization. See Annex C.

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
Values used in this Standard are in SI units. Additional accepted units are in accordance with the ISO 80000 Series of Standards. Values given in parentheses are for information only.
