Paper - Determination of bursting strength (ISO 2758:2014)
ISO 2758:2014 specifies a method for measuring the bursting strength of paper submitted to increasing hydraulic pressure. It is applicable to paper having bursting strengths within the range 70 kPa to 1 400 kPa. It is not intended to be used for the components (such as fluting medium or linerboard) of a combined board, for which the method given in ISO 2759 is more suitable.
Papier - Bestimmung des Berstdruckes (ISO 2758:2014)
Diese Internationale Norm legt ein Verfahren zum Messen des Berstdruckes von Papier fest, wobei die Probe zunehmendem hydraulischen Druck ausgesetzt ist. Sie ist auf Papier mit Berstdrücken in einem Bereich von 70 kPa bis 1 400 kPa anwendbar. Die Anwendung ist nicht für Einzelkomponenten (wie für Papier, die für die gewellten und ungewellten Lagen von Wellpappe dienen) von mehrlagigem Karton vorgesehen. Für dieses Verfahren ist ISO 2759 [1] besser geeignet.
Aufgrund mangelnder wirtschaftlicher Vereinbarungen, welches Verfahren für welches zu prüfende Material angewendet werde sollte, sollten Materialien mit Berstdrücken unter 600 kPa nach dieser Internationalen Norm geprüft werden.
Papier - Détermination de la résistance à l'éclatement (ISO 2758:2014)
ISO 2758:2014 spécifie une méthode de mesurage de la résistance à l'éclatement du papier soumis à une pression hydraulique croissante. Elle est applicable aux papiers ayant une résistance à l'éclatement comprise entre 70 kPa et 1 400 kPa. Elle n'est pas destinée à être utilisée pour les constituants (tels que le papier à canneler ou le carton de couverture) d'un carton mixte, pour lesquels la méthode figurant dans l'ISO 2759 convient mieux.
Papir - Določevanje razpočne trdnosti (ISO 2758:2014)
Standard EN ISO 2758 določa metodo za merjenje razpočne trdnosti papirja, podvrženega naraščajočemu hidravličnemu tlaku. Uporablja se za papir z razpočno trdnostjo v razponu 70 kPa do 1400 kPa. Ni namenjen uporabi za komponente (kot je nagubani papir ali podložna lepenka) kombiniranega kartona in lepenke, za katera je primernejša metoda iz standarda ISO 2759[1]. Če ni poslovnega sporazuma v zvezi s tem, katera metoda naj se uporabi za preskušanje materiala, naj bi se materiali z razpočno trdnostjo pod 600 kPa preskusili v skladu s tem mednarodnim standardom.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

Introduction
This International Standard is applicable to papers with bursting strengths in the range 70 kPa to
1 400 kPa.
For materials with bursting strengths equal to or greater than 350 kPa (or 250 kPa for the components
[1]
of combined materials), an alternative method, based on similar principles, is specified in ISO 2759
All components of solid and corrugated fibreboard, irrespective of bursting strength, should be tested
according to ISO 2759.
In view of the overlap between the method for testing papers and boards and in the absence of any
commercial agreement, materials below 600 kPa should be tested according to this International
Standard.
NOTE Due to differences in the specification of the apparatus, tests made on the same material using the
procedures of ISO 2759 and this International Standard will not necessarily give the same results.
INTERNATIONAL STANDARD ISO 2758:2014(E)
Paper — Determination of bursting strength
1 Scope
This International Standard specifies a method for measuring the bursting strength of paper submitted
to increasing hydraulic pressure. It is applicable to paper having bursting strengths within the range
70 kPa to 1 400 kPa. It is not intended to be used for the components (such as fluting medium or
[1]
linerboard) of a combined board, for which the method given in ISO 2759 is more suitable.
In the absence of any commercial agreement as to which method should be used for testing the material,
materials with bursting strengths below 600 kPa should be tested according to this International
Standard.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 186, Paper and board — Sampling to determine average quality

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
bursting strength
maximum pressure developed by the hydraulic system in forcing an elastic diaphragm through a circular
area of the paper when the pressure is applied in the manner described in the method
Note 1 to entry: The indicated bursting pressure includes the pressure required to extend the diaphragm during
the test.
3.2
burst index
bursting strength of paper, in kilopascals, divided by the grammage of the paper determined in
accordance with ISO 536
4 Principle
A test piece, placed over a circular elastic diaphragm, is rigidly clamped at the periphery but free to
bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, bulging the diaphragm until
the test piece ruptures. The bursting strength of the
