Pulps - Laboratory wet disintegration - Part 2: Disintegration of mechanical pulps at 20 degrees C (ISO 5263-2:2004)

ISO 5263-2:2004 specifies an apparatus and the procedures for the laboratory-wet disintegration of mechanical pulps that do not exhibit latency or pulps where latency has already been removed. 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 mechanical pulps (i.e. mechanical, semi-chemical and chemo-mechanical pulps) that do not exhibit latency, including recovered fibres from mechanical pulps. It is not suitable for mechanical pulps exhibiting latency for which the disintegration procedure described in ISO 5263-3 shall be used.
The procedure specified by ISO 5263-2:2004 should also be used to disintegrate all mechanical pulps to be measured for brightness.

Faserstoffe - Nassaufschlagen im Labor - Teil 2: Aufschlagen von Holzstoff bei 20 grad C (ISO 5263-2:2004)

Dieser Teil der ISO 5263 legt ein Gerät und ein Verfahren zum Nassaufschlagen von Holzstoffen im Labor ohne oder mit bereits beseitigter Latenz fest. Das Gerät und das Verfahren finden auch zur Probenvorbereitung in mehreren anderen Internationalen Normen zum Thema Faserstoffe Anwendung.
Grundsätzlich ist das Verfahren für alle latenzfreien Holzstoffarten anwendbar (z. B. Holzstoffe, Halbzellstoff und chemische Holzstoffe) - aus Holzstoffen gewonnene Sekundärfaserstoffe eingeschlossen. Es ist nicht geeignet für Holzstoffe mit Latenz, für die das in ISO 5263-3 beschriebene Aufschlagverfahren zu verwenden ist.
Das in ISO 5263-2 festgelegte Verfahren sollte auch zum Aufschlagen all der Holzstoffarten verwendet werden, die auf den Weißgrad untersucht wurden.
ANMERKUNG   Der Weißgrad wird durch das Vorhandensein von Latenz nicht signifikant beeinflusst; bei der Heißzerfaserung  von Holzstoffen kann es jedoch zu signifikanten Weißgradverlusten kommen.

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 5263-2 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 partially 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
