Pulps - Laboratory wet disintegration (ISO 5263:1995)

Halbstoffe - Naßaufschlagen im Laboratorium (ISO 5263:1995)

Diese Internationale Norm legt ein Gerät und ein Verfahren zum Naßaufschlagen von Halbstoffen fest. Es beschreibt das Aufschlaggerät und in einigen Fällen das Aufschlag-Verfahren, das für eine Anzahl von Internationalen für Halbstoffarten angegeben wird. Grundsätzlich ist dieses Verfahren auf die meisten Zellstoffarten - einschließlich Sekundärfasern - anwendbar. Es ist ungeeignet für einige Langfaserstoffe, wie solche aus Baumwolle oder ähnlichen Materialien. Es wird als solches nicht zum Entfernen der Latenz von Holzstoffen empfohlen.

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. Esch 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.
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.
International Standard ISO 5263 was prepared by Technical Committee
lSO/TC 6, Paper, board and pulps, Subcommittee SC 5, Test methods and
quality specifica tions for Pulps.
This second edition cancels and replaces the first edition (ISO 5263:1979),
of which it constitutes a technical revision.
Annexes A and B form an integral part of this International Standard.
