Pulps - Preparation of laboratory sheets for physical testing - Part 2: Rapid-Köthen method (ISO 5269-2:2004)

ISO 5269-2:2004 specifies a method, using a Rapid-Köthen 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.
ISO 5269-2:2004 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.

Faserstoffe - Laborblattbildung für physikalische Prüfungen - Teil 2: Rapid-Köthen-Verfahren (ISO 5269-2:2004)

Dieser Teil der ISO 5269 legt ein Verfahren für die Blattbildung zur Herstellung von Laborblättern auf einer
Rapid-Köthen-Blattbildungseinrichtung fest. Die so hergestellten Laborblätter können anschließend
physikalischen Prüfungen unterzogen werden, um die relevanten Eigenschaften des Faserstoffes zu
bestimmen.
Dieser Teil der ISO 5269 ist auf die Mehrzahl aller Faserstoffe anwendbar, eignet sich jedoch nicht für
besonders langfaserige Faserstoffe, wie sie beispielsweise aus ungekürzter Baumwolle, Flachs und ähnlichen
Rohstoffen hergestellt werden.
Ferner ist dieses Verfahren nicht für die Herstellung von Laborblättern zur Bestimmung des diffusen blauen
Reflexionsfaktors (ISO-Weißgrad) nach ISO 3688 [1] geeignet.
WARNUNG - Wenn langfaseriger Zellstoff in ungekürzter Form verwendet wird, ist die Blattformation
nicht immer zufrieden stellend.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 5269-2 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps, Subcommittee SC 5,
Test methods and quality specifications for pulps.
This third edition cancels and replaces the second edition (ISO 5269-2:1998), of which the Introduction,
Clauses 1, 2 and 7 and Subclause 5.1 have been revised.
ISO 5269 consists of the following parts, under the general title Pulps — Preparation of laboratory sheets for
physical testing:

 Part 2: Rapid-Köthen method

ISO 5269-2:2004(E)
Introduction
It has been agreed that the ultimate aim of standardization of the preparation of laboratory sheets should be to
develop one method which is internationally acceptable and which, if possible, permits the use of different
types of sheet-making apparatus.
For practical reasons, it has not proved possible to achieve this at present. Therefore, as an interim measure,
in view of the widespread use of equipment described in this part of ISO 5269, it has been decided to provide
agreed guidance on the use of different types of equipment in order to achieve consistency of results with
each method.
To avoid creating too many levels of results, the method specified in this part of ISO 5269 should preferably
be used with the PFI mill method of laboratory beating according to ISO 5264-2. The method specified in
ISO 5269-1 (Conventional sheet-former method) should preferably be used with the Valley beater or PFI mill
[2]
methods of laboratory beating according to ISO 5264-1 and 5264-2, respectively.

INTERNATIONAL STANDARD ISO 5269-2:2004(E)

Pulps — Preparation of laboratory sheets for physical testing —
Part 2:
Rapid-Köthen method
1 Scope
This part of ISO 5269 specifies a method, using a Rapid-Köthen 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
[1]
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.

3 Principle
A circular sheet is formed from a pulp suspension on a wire screen under suction. The sheet is subjected to
pressure and dried in a dryer, with almost complete prevention of shrinkage, in a specified way with respect to
the pressure applied, the suction and the temperature.

4.1 Rapid-Köthen apparatus, consisting of a sheet former, transfer equipment, one or more dryers and
accessories (see Figure 1). The parts of the instrument which come into contact with stock or water shall be
corrosion resistant.
4.1.1 Sheet former, consisting of a stock container for preparing the pulp suspension, the screen section
on which wet fibre is forwarded, and the suction chamber for drawing off and holding the water after passing
through the screen. The lower part of the stock container, screen section and suction chamber may be sealed
off.
4.1.1.1 Stock container (see Figure 1)
The stock container consists of a transparent cylindrical tube (1) with an internal diameter of
200 mm ± 0,5 mm and a capacity of not less than 10 litres. The container is graduated in litres. Around the
