T/SSM 4-2021 The determination method for residual dimethyl sulfoxide content in polyacrylonitrile-based carbon fiber precursor using acetone method
Basic Information
Scope
Scope: This document specifies the method for determining the content of dimethyl sulfoxide, a residual solvent in polyacrylonitrile-based carbon fiber precursor filament (acetone method). This document is applicable to the determination of the content of dimethyl sulfoxide, a residual solvent, in polyacrylonitrile-based carbon fiber precursor filament after the washing process. Main technical content: This document specifies the method for determining the content of dimethyl sulfoxide, a residual solvent, in polyacrylonitrile-based carbon fiber precursor filament (acetone method). This document is applicable to the determination of the content of dimethyl sulfoxide, a residual solvent, in polyacrylonitrile-based carbon fiber precursor filament after the washing process.
