Pulps — Laboratory wet disintegration — Part 1: Disintegration of chemical pulps
ISO 5263-1:2004 specifies an apparatus and the procedure for the laboratory-wet disintegration of chemical pulps. This apparatus and procedure are required for preparation of the test portion in a number of other International Standards dealing with pulps. In principle, this method is applicable to all kind of chemical pulps, including recovered fibres. It is not suitable for mechanical pulps and some very long-fibred chemical pulps such as those from cotton and similar materials.

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 5263-1 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps, Subcommittee SC 5,
Test methods and quality specifications for pulps.
This first edition cancels and replaces ISO 5263:1995 which has been technically revised. In the revision,
ISO 5263 has been divided into three parts; Part 1 which is applicable to chemical pulps, Part 2 which is
applicable to mechanical pulps without latency and Part 3 which is applicable to mechanical pulps exhibiting
latency. In Part 3, an informative Annex has been inserted describing the effect of latency in mechanical pulps.
ISO 5263 consists of the following parts, under the general title Pulps — Laboratory wet disintegration:
— Part 1: Disintegration of chemical pulps
— Part 2: Disintegration of mechanical pulps at 20 °C
— Part 3: Disintegration of mechanical pulps at W 85 °C

INTERNATIONAL STANDARD ISO 5263-1:2004(E)
Pulps — Laboratory wet disintegration —
Part 1:
Disintegration of chemical pulps
1 Scope
This part of ISO 5263 specifies an apparatus and the procedure for the laboratory-wet disintegration of
chemical pulps. This apparatus and procedure are required for preparation of the test portion in a number of
other International Standards dealing with pulps.
In principle, this method is applicable to all kind of chemical pulps, including recovered fibres. It is not suitable
for mechanical pulps and some very long-fibred chemical pulps such as those from cotton and similar
materials.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 638, Pulps — Determination of dry matter content
ISO 4119, Pulps — Determination of stock concentration
ISO 14487, Pulps — Standard water for physical testing
3 Definition
For the purposes of this part of ISO 5263, the following definition applies.
3.1
disintegration of chemical pulp
mechanical treatment in water so that interlaced fibres, which were free in the pulp stock, are again separated
from one another without appreciably changing their structural properties
4 Apparatus
Ordinary laboratory apparatus and the following:
4.1 Standard disintegrator, as described in Annex A.
NOTE The procedure for checking the Standard disintegrator is given in Annex B.
4.2 Balance, capable of weighing with an accuracy of ± 0,2 g.
4.3 Standard water, for physical testing, as specified in ISO 14487.
