Preface
This is the first edition of CSA Z5300, Cellulose filaments (CF) – Preparing handsheets for physical tests.
This Standard describes methods for the preparation of handsheets of cellulose filaments (CF) and CF-reinforced pulp handsheets for physical properties testing. The properties of the handsheets can be studied to give an indication of the performance of CF as a reinforcement additive in the production of paper or tissue.
This Standard is the third in a series on cellulose nanomaterials intended to serve as a foundation for the development of both Canadian and international standards to facilitate the introduction of cellulose nanomaterials into global markets. Other standards in the series on cellulose nanomaterials include CSA Z5100, Cellulose nanomaterials — Test methods for characterization and CSA Z5200, Cellulose nanomaterials — Blank detail specification.
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 describes methods for the preparation of low-basis weight handsheets of cellulose filaments (CF) and CF-reinforced pulp handsheets to be used for physical tests.
1.2
This Standard also covers the preparation of low-basis weight handsheets of cellulose microfibrils (CMF) and cellulose nanofibrils (CNF), and CMF- or CNF-reinforced pulp handsheets, provided that handsheets of acceptable quality can be obtained using the methods described.
1.3
This Standard does not cover the preparation of handsheets of CF, CMF, or CNF for optical tests.
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.
