Pulps - Estimation of dirt and shives - Part 1: Inspection of laboratory sheets by transmitted light (ISO 5350-1:2006)
ISO 5350-1:2006 specifies a method for the estimation by transmitted light of the visible dirt and shives in laboratory sheets prepared from pulp. It is, in principle, applicable to all kinds of pulp, although it is mainly intended for pulp that is not manufactured in sheet form.
ISO 5350-1:2006 can also be applied to mill sheeted pulp, if the sheets have high grammage or are very opaque for other reasons, in which case ISO 5350-2:2006 is not applicable.
ISO 5350-1:2006 is not intended for recycled pulp.
Faserstoff - Bewertung von Schmutz und Splittern - Teil 1: Prüfung von Laborblättern mit dem Durchlicht-Verfahren (ISO 5350-1:2006)
Dieser Teil der ISO 5350 legt die Vorgehensweise für das Durchlicht-Verfahren fest, das zur Bewertung von sichtbarem Schmutz und Splittern in Laborblättern dient, welche aus Faserstoffen hergestellt wurden. Diese Internationale Norm ist grundsätzlich auf alle Sorten von Faserstoff anwendbar, obwohl sie hauptsächlich für Faserstoffe vorgesehen ist, die nicht in Bogenform hergestellt sind.
Dieser Teil der ISO 5350 kann auch für Zellstoff angewendet werden, wenn die Probebogen aufgrund ihrer hohen flächenbezogenen Masse oder aus anderen Gründen eine hohe Opazität aufweisen. Diese Faserstoffe können nicht mit den Prüfverfahren nach ISO 5350-2 bestimmt werden.
Dieser Teil der ISO 5350 ist nicht für Altpapierstoffe bestimmt.
ANMERKUNG Die Bestimmung von Splittern in Holzstoffen erfolgt üblicherweise durch mechanische Trennelemente oder optische Untersuchungsverfahren. Verschiedene Holzstoffarten können Probleme bei der Herstellung von Laborblättern oder bei der Prüfung selbst verursachen. In solchen Fällen ist dieser Teil der ISO 5350 nicht anwendbar.
Pâtes - Estimation des impuretés et bûchettes - Partie 1: Examen des feuilles de laboratoire par lumière transmise (ISO 5350-1:2006)
L'ISO 5350-1:2006 spécifie une méthode pour l'estimation par lumière transmise des impuretés et bûchettes visibles dans des feuilles de laboratoire préparées à partir de pâtes. En principe, elle est applicable à tous les types de pâte bien qu'elle soit principalement destinée aux pâtes qui ne sont pas fabriquées en feuilles.
L'ISO 5350-1:2006 est également applicable aux pâtes fabriquées en feuilles si les feuilles ont un grammage élevé ou sont très opaques pour d'autres raisons, auquel cas l'ISO 5350-2 ne s'applique pas.
L'ISO 5350-1:2006 n'est pas destinée aux pâtes recyclées.

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 5350-1 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 5350-1:1998, ISO 5350-1:1998/Cor.1:1999),
which has been technically revised.
With regard to ISO 5350-1:1998 and Technical Corrigendum 1:1999, the following changes have been made:
a) the normative references have been updated;
b) a more precise description of the sampling and preparation of test pieces was given;
c) precision data have been moved from informative Annex B to 8.3;
d) the status of the annex for the instrumental procedure has been changed from normative to informative
and a more precise description of the instrumental procedure was given;
e) editorial updating.
ISO 5350 consists of the following parts, under the general title Pulps — Estimation of dirt and shives:
⎯ Part 1: Inspection of laboratory sheets by transmitted light
⎯ Part 2: Inspection of mill sheeted pulp by transmitted light
⎯ Part 3: Visual inspection by reflected light using Equivalent Black Area (EBA) method
⎯ Part 4: Instrumental inspection by reflected light using Equivalent Black Area (EBA) method

ISO 5350-1:2006(E)
Introduction
This part of ISO 5350 is based upon visual inspection. Informative Annex B is used when the inspection is
performed by instrumental devices. For the time being, though, visual inspection provides the basis for this
part of ISO 5350. This will eventually be changed when more experience with instrumental devices is gained,
and it has been shown that such equipment can estimate dirt and shives to an acceptable level of precision at
least equal to visual inspection.
This part of ISO 5350 is complementary to ISO 5350-2, which concerns visual inspection of mill sheeted pulp
by transmitted light, and ISO 5350-3, which concerns visual inspection by reflected light.
ISO 5350-4 is based on automatic inspection by reflected light.
INTERNATIONAL STANDARD ISO 5350-1:2006(E)
Pulps — Estimation of dirt and shives —
Part 1:
Inspection of laboratory sheets by transmitted light
1 Scope
This part of ISO 5350 specifies a method for the estimation by transmitted light of the visible dirt and shives in
laboratory sheets prepared from pulp. It is, in principle, applicable to all kinds of pulp, although it is mainly
intended for pulp that is not manufactured in sheet form.
This part of ISO 5350 can also be applied to mill sheeted pulp, if the sheets have high grammage or are very
opaque for other reasons, in which case ISO 5350-2 is not applicable.
This part of ISO 5350 is not intended for recycled pulp.
NOTE Shives in mechanical pulp are usually determined by means based on screening or optical analyses. Some
grades of mechanical pulps can cause problems in sheet-making or inspection, which makes this part of ISO 5350
impractical.
