ISO 5269-2:2004 PDF

Scope: This part of ISO 5269 specifies a method, using a Rapid-Kothen 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 ISO 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 ISO 3688 WARNING — When long-fibred pulp is used in the unshortened form, the sheet formation may not always be satisfactory.
