Pulps - Laboratory sheets - Determination of physical properties (ISO 5270:2012)
This International Standard specifies the relevant International Standards to be used for the determination of physical properties of laboratory sheets made of all kind of pulps. It is applicable to laboratory sheets prepared in accordance with ISO 5269-1, ISO 5269-2 or ISO 5269-3. In this International Standard, it is left to the pulp producer and the pulp user to agree upon which properties are relevant to be tested. The results are, if applicable, reported in index form.
Faserstoff- Laborblätter- Bestimmung der physikalischen Eigenschaften (ISO 5270:2012)
Diese Internationale Norm weist auf die relevanten Internationalen Normen hin, die für die Bestimmung der
physikalischen Eigenschaften von aus Zellstoff hergestellten Laborblättern benutzt werden. Sie ist für
Laborblätter vorgesehen, die entsprechend ISO 5269-1 [1], ISO 5269-2 [2] oder ISO 5269-3 [3] vorbereitet
wurden. Die zu prüfenden relevanten Eigenschaften sind zwischen Hersteller und Zellstoff-Abnehmer zu
vereinbaren.
Zur Bestimmung der physikalischen Eigenschaften verweist ISO 5270 auf die relevanten Internationalen
Normen für die Beschreibung und Kalibrierung der einzusetzenden Geräte, sowie für die Berechnung und
Angabe der Ergebnisse. Diese Internationale Norm legt jedoch die Arbeitsschritte zur Prüfung von
Laborblättern fest, bei denen die Menge des Prüfmaterials begrenzt ist. Verglichen werden die Prüfungen von
Papier und Pappe, auf die die relevanten Internationalen Normen hinweisen und welche anwendbar sind.
Deshalb kann es zu Abweichungen kommen.
Diese Internationale Norm beinhaltet Prüfungen an Blättern mit niedriger und großer flächenbezogener
Masse, die nach ISO 5269-1, ISO 5269-2 oder ISO 5269-3 vorbereitet wurden.
Mit einem konventionellen Blattbildner nach ISO 5269-1 und ISO 5269-3 muss die ofentrockene
flächenbezogene Masse aus dem Bereich der niedrigeren flächenbezogenen Masse (60 ± 2) g/m² betragen
bzw. (75 ± 2) g/m², wenn ein Blattbildner nach Rapid-Köthen entsprechend ISO 5269-2 und ISO 5269-3
benutzt wurde. Die ofentrockene flächenbezogene Masse aus dem Bereich der großen flächenbezogenen
Masse muss 140 g/m² mit einer Toleranz von 3 % betragen, wenn der konventionelle- und Rapid-Köthen-
Blattbildner benutzt wurde. Eine Ausnahme bildet die Bruchkraft in z-Richtung, bei der die flächenbezogene
Masse ≥ 90 g/m² sein muss.
Pâtes - Feuilles de laboratoire - Détermination des propriétés physiques (ISO 5270:2012)
L'ISO 5270:2012 spécifie les Normes internationales à utiliser pour la détermination des propriétés physiques des feuilles de laboratoire fabriquées à partir de pâtes de tous types. Elle est applicable à des feuilles de laboratoire préparées conformément à l'ISO 5269‑1, l'ISO 5269‑2 ou l'ISO 5269‑3.
Dans l'ISO 5270:2012, il est laissé à l'initiative du fabricant de pâte et de l'utilisateur de la pâte de convenir des propriétés pertinentes à soumettre à essai. Les résultats sont consignés, s'il y a lieu, sous forme d'indice.

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 5270 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 5270:1998), which has been technically revised.
The list of relevant International Standards for paper and board, to be used for testing the physical properties
of laboratory sheets, has been updated and new standards, such as ISO 1924-3 and ISO 15754, have been
included. The option to determine air permeance, using the Bendtsen method (ISO 5636-3) or the Sheffield
method (ISO 5636-4) has been inserted, as well as the option to measure optical properties.

Introduction
This International Standard includes the determination of physical properties of both “low grammage” sheets
and “high grammage” sheets, prepared in accordance with ISO 5269-1, ISO 5269-2 or ISO 5269-3. The
2
oven-dry grammage of the “low grammage” sheets is (60 ± 2) g/m using the conventional sheet former, as
2
described in ISO 5269-1 and ISO 5269-3, or (75 ± 2) g/m using the Rapid-Köthen sheet former, as described
2
in ISO 5269-2 and ISO 5269-3. The oven-dry grammage of the “high grammage” sheets is 140 g/m , with a
tolerance of 3 % using the conventional and the Rapid Köthen sheet formers, except for the z-directional tensile
2
strength where the grammage is ≥ 90 g/m .
For determination of physical properties, ISO 5270 refers to the relevant International Standards for paper
and board for the description and calibration of the required equipment, and for the calculation and reporting
of results. This International Standard, however, specifies the procedures for testing laboratory sheets where
the amount of material is limited, compared to testing of paper and board to which the relevant International
Standards referred to are applicable, and for that reason there may be a discrepancy.

Determination of physical properties of laboratory sheets using the procedure and equipment described in the
relevant International Standards given in Tables 1 and 2. The results are, if applicable, reported in index form.
NOTE The properties to be measured are jointly determined by the pulp producer and the pulp user.

5.1 Selection of laboratory sheets
Depending on the properties to be tested, determine the number of laboratory sheets required (see Table 1
and/or Table 2). The specification of the number of test pieces needed for each property defines the area
required for testing and thus the number of sheets.
Each sheet shall be free of visible defects.
