Preface:
This is the first edition of CSA W206, Kraft lignin — Glass transition temperature by differential scanning calorimetry.
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 a method for the determination of the glass transition temperature (Tg) of kraft lignin. The procedure utilizes differential scanning calorimetry (DSC).
This procedure is applicable to solid lignins (e.g., powdered form) isolated from the kraft pulping process.
It does not apply to raw black liquor and lignin in the sodium form produced from the kraft pulping process.
1.2
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.
