Pulps. Preparation of laboratory sheets for physical testing -- Conventional sheet-former method
This part of ISOÂ 5269 specifies a method, using a conventional sheet former, for the preparation of laboratory sheets of pulp for the purpose of carrying out subsequent physical tests on these sheets in order to assess the relevant properties of the pulp itself.
This part of ISOÂ 5269 is applicable to most kinds of pulp. It is not suitable for some pulps with very long fibres, such as those made from unshortened cotton, flax and similar materials.
This method is not suitable for the preparation of laboratory sheets for the determination of diffuse blue reflectance factor (ISO brightness) in accordance with ISOÂ 3688[1].
WARNING — When long-fibred pulp is used in the unshortened form, the sheet formation may not always be satisfactory.
