Pulps - Laboratory beating - Part 2: PFI mill method (ISO 5264-2:2002)

ISO 5264-2:2002 specifies a method, using a PFI mill, for the laboratory beating of pulp. The description is limited to the sampling and beating of the pulp, the withdrawal and distribution of samples, and the beating equipment.
NOTE Beating is a preliminary step in testing the physical properties of pulp.
In principle, this method is applicable to all kinds of chemical and semi-chemical pulps. In practice, the method may not give satisfactory results with certain pulps with extremely long fibres.

Pâtes - Raffinage de laboratoire - Partie 2: Méthode au moulin PFI (ISO 5264-2:2002)

L'ISO 5264:2002 spécifie une méthode utilisant un moulin PFI pour le raffinage de la pâte en laboratoire. La description se limite à l'échantillonnage et au raffinage en pile de la pâte, au prélèvement et à la répartition des échantillons, ainsi qu'à l'appareillage de raffinage.
NOTE Le raffinage en pile est une phase préliminaire dans la détermination des propriétés physiques d'une pâte.
En principe, la présente méthode est applicable à tous les types de pâtes chimiques et mi-chimiques. En pratique, cette méthode peut ne pas donner de résultats satisfaisants avec certaines pâtes à fibres extrêmement longues.

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 3.
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 part of ISO 5264 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 5264-2 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps,
Subcommittee SC 5, Test methods and quality specifications for pulps.
This second edition cancels and replaces the first edition (ISO 5264-2:1979), which has been technically revised.
ISO 5264 consists of the following parts, under the general title Pulps — Laboratory beating:
— Part 1: Valley beater method
— Part 2: PFI mill method
— Part 3: Jokro mill method
Annexes A and B form a normative part of this part of ISO 5264. Annex C is for information only.

Introduction
In view of the widespread use of the following beaters:
— Valley beater;
— PFI mill;
— Jokro mill;
it has been decided to provide guidance on the use of these beaters in order to achieve consistency of results with
each instrument. Although all three beaters show similar trends in the effect on pulp properties, there is no correlation
between the actual results obtained with the different types of beaters.
ISO 5264-1 specifies a method of laboratory beating using a Valley beater and ISO 5264-3 a method using a Jokro
mill.
Beating is a preliminary step in the preparation of laboratory sheets for testing the physical properties of pulps. In the
PFI mill, each beating is performed separately, i.e. a new test portion of unbeaten pulp is taken for each beating.
NOTE A complete test of physical properties normally comprises unbeaten pulp and several beatings of the same pulp, where
the beating is carried out for different numbers of roll revolutions. The number of roll revolutions depends on the type of pulp and
the beating load. After beating, the drainability is measured according to ISO 5267-1 or ISO 5267-2, and laboratory sheets are
prepared according to ISO 5269-1 or ISO 5269-2.

1 Scope
This part of ISO 5264 specifies a method, using a PFI mill, for the laboratory beating of pulp. The description is
limited to the sampling and beating of the pulp, the withdrawal and distribution of samples, and the beating
equipment.
NOTE Beating is a preliminary step in testing the physical properties of pulp.
In principle, this method is applicable to all kinds of chemical and semi-chemical pulps. In practice, the method may
not give satisfactory results with certain pulps having extremely long fibres.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 5264. For dated references, subsequent amendments to, or revisions of, any of these publications do
not apply. However, parties to agreements based on this part of ISO 5264 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of
currently valid International Standards.

3 Principle
A measured amount of pulp at a specified stock concentration is beaten between a roll with bars and a smooth beater
housing, both rotating in the same direction, but at different peripheral speeds.

4.1 PFI mill, as specified in annex A.
See normative annex B and informative annex C.
4.2 Disintegrator, as specified in ISO 5263.
4.3 Balance, capable of weighing the sample with an error of less than ± 0,2 g.

4.4 Standard water, purified to an electrical conductivity � 0,25 mS/m at 25 C, as specified in ISO 14487.
4.5 A reference pulp, kept for beating-control purposes and stored for a time sufficiently long to avoid further
changes in physical properties. The reference pulp should, if possible, be of the same grade as that normally beaten
in the beating equipment concerned. Since some pulp grades are not stable, it might be necessary to choose
another grade.
To avoid the influence of storage time, the reference pulp should be kept at room temperature (not at too high a
relative humidity) in a dark and dust-free place.
NOTE Stored under the recommended conditions, the reference pulp will, in most cases, be stable for approximately 10 years.
Changes in the level of the tensile strength and tear strength values may be an indication that the reference pulp is no longer
stable. The stability can be checked by measuring the viscosity of the reference pulp, e.g. twice a year.
5 Sampling
If the beating is being done to evaluate a lot of pulp, the sample shall be selected in accordance with ISO 7213.
If the beating is done on another type of sample, report the source of the sample and, if possible, the sampling
procedure used.
Select the test portions so that they are representative of the gross sample received.
6 Preparation of sample
If the sample is wet or air-dry, weigh a test portion for the determination of dry-matter content in accordance with
ISO 638. If the sample is in the form of an aqueous pulp suspension, determine the dry matter content in accordance
with ISO 4119.
Take a test portion of the sample corresponding to (30,0± 0,5) g of oven-dry pulp. Do not cut pulp sheets and avoid
the use of cut edges. If the sample is in the form of machine-dried sheets or flash-dried slabs, soak the pulp
thoroughly in 0,5 litre of standard water (4.4) at room temperature for not less than 4h. Tear the soaked pulp into
pieces approximately 25 mm× 25 mm in size. It is essential that the pulp sample be thoroughly softened by soaking,
to ensure that the preliminary disintegration leads to only a minimal beating effect. Wet pulps may be disintegrated
without soaking.
7 Procedure
7.1 General
For each test portion (each degree of beating), carry out the following procedure.
7.2 Disintegration
Disintegrate the initially wet portion or the soaked test portion as described in ISO 5263. Use standard water (4.4) at
