Fibre ropes - Determination of certain physical and mechanical properties (ISO 2307:2010)
ISO 2307:2010 specifies, for ropes of different kinds, a method of determining each of the following characteristics:
linear density;
lay length;
braid pitch;
elongation;
breaking force.
The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension.
The elongation corresponds to the measured increase in length of the rope when the tension to which it is subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum specified breaking strength of the rope.
The breaking force is the maximum force registered (or reached) during a breaking test on the test piece, carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking force values given in the tables of rope specifications are only valid when this type of testing machine is used.
ISO 2307:2010 also provides a method for measuring water repellency, lubrication and finish content, and heat setting treatment, when requested by the customer.
Faserseile - Bestimmung einiger physikalischer und mechanischer Eigenschaften (ISO 2307:2010)
Diese Internationale Norm legt für unterschiedliche Seilarten ein Verfahren zur Bestimmung der folgenden
Eigenschaften fest:
― Feinheit (linear density);
― Schlaglänge;
― Flechtlänge;
― Dehnung;
― Bruchkraft.
Feinheit (lineare Masse), Schlaglänge und Flechtlänge werden an einem Seil unter festgelegter Spannung
gemessen, die als Nennspannung oder Bezugsspannung bezeichnet und in Anhang A festgelegt wird.
Die Dehnung entspricht der gemessenen Verlängerung des Seils, wenn die Spannung, der es ausgesetzt
wird, von einem Anfangswert (der Nennspannung) auf einen Wert gesteigert wird, der 50 % der festgelegten
Mindestbruchfestigkeit des Seils beträgt.
Die Bruchkraft ist die maximale Kraft, die bei einer Bruchprüfung, die auf einer Zugprüfmaschine mit
konstanter Fahrgeschwindigkeit des beweglichen Teils durchgeführt wird, an dem Prüfstück registriert (oder
erreicht) wird. Die in den Tabellen für Seilanforderungen angegeben Werte für die Bruchkraft gelten nur, wenn
diese Art Prüfmaschine verwendet wird.
Wenn es nicht möglich ist, den gesamten Querschnitt des Seiles zu prüfen, darf das in Anhang B
beschriebene Verfahren angewendet werden, um als Vereinbarung zwischen betroffenen Parteien zu dienen.
Diese Internationale Norm stellt auf Kundenanforderung auch ein Verfahren zum Messen der Wasserabstoßung,
des Gehalts an Batschmittel und Appretur sowie zum Prüfen der Thermofixierung zur Verfügung.
Cordages en fibres - Détermination de certaines caractéristiques physiques et mécaniques (ISO 2307:2010)
L'ISO 2307:2010 spécifie, pour des cordages de différents types, une méthode pour la détermination de chacune des caractéristiques suivantes:
masse linéique;
pas de commettage;
pas de tressage;
allongement;
force de rupture.
La masse linéique, le pas de commettage et le pas de tressage sont mesurés, le cordage étant soumis à une force de traction définie, dite force de traction de référence.
L'allongement correspond à l'augmentation de longueur du cordage mesurée lorsque la force de traction à laquelle ce dernier est soumis passe d'une valeur initiale (force de traction de référence) à une valeur correspondant à 50 % de la résistance minimale à la rupture spécifiée pour le cordage.
La force de rupture est la force maximale enregistrée (ou atteinte) au cours d'un essai de rupture de l'éprouvette, réalisé sur une machine d'essai de traction avec déplacement à vitesse constante de l'élément mobile. Les valeurs des forces de rupture données dans les tableaux de spécifications des cordages ne sont valables qu'en cas d'utilisation de machines d'essai de ce type.
L'ISO 2307:2010 fournit également une méthode de détermination de la résistance à l'absorption d'eau, une méthode de détermination de la teneur en lubrifiant et en apprêt, et une méthode permettant de déterminer si le cordage a subi un traitement de thermo-fixation, à la demande du client.
Vlaknene vrvi - Ugotavljanje nekaterih fizikalnih in mehanskih lastnosti (ISO 2307:2010)
Ta mednarodni standard določa za različne vrste vrvi metodo ugotavljanja vsake od naslednjih značilnosti:
⎯ linearna gostota;
⎯ dolžina pletenja;
⎯ nagib pletenice;
⎯ raztezek;
⎯ pretržna sila.
Linearna gostota, dolžina pletenja in nagib pletenice so merjeni z vrvjo pod določeno napetostjo, imenovano referenčna napetost, kot je določeno v dodatku A.
Raztezek ustreza izmerjenemu povečevanju dolžine vrvi, kadar je napetost, kateri je vrv izpostavljena, povečana od začetne vrednosti (referenčna napetost) do vrednosti, enaki 50 % minimalne določene pretržne moči vrvi.
Pretržna sila je maksimalna ugotovljena (ali dosežena) sila med pretržnim preskusom na preskušancu, izpeljanim na napravi za natezni preskus s konstantno prečno vrednostjo premikajočega se elementa. Vrednosti pretržne sile, podane v preglednicah specifikacij vrvi, veljajo le, kadar se uporabi ta vrsta preskusne naprave. Kadar ni mogoče preskusiti celotnega odseka vrvi, je lahko uporabljena metoda opisana v dodatku B, ki je predmet dogovora med udeležinimi strankami.
Ta mednarodni standard prav tako zagotavlja metodo za merjenje odbojnosti vode, mazanja in končno vsebnost ter obdelave za termostabiliziranje, kadar to zahteva stranka.

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 2307 was prepared by Technical Committee ISO/TC 38, Textiles.

INTERNATIONAL STANDARD ISO 2307:2010(E)
Fibre ropes — Determination of certain physical and
mechanical properties
1 Scope
This International Standard specifies, for ropes of different kinds, a method of determining each of the
following characteristics:
⎯ linear density;
⎯ lay length;
⎯ braid pitch;
⎯ elongation;
⎯ breaking force.
The linear density, lay length and braided pitch are measured with the rope under a specified tension called
the reference tension, as specified in Annex A.
The elongation corresponds to the measured increase in length of the rope when the tension to which it is
subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum
specified breaking strength of the rope.
The breaking force is the maximum force registered (or reached) during a breaking test on the test piece,
carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking
force values given in the tables of rope specifications are only valid when this type of testing machine is used.
When it is not possible to test the whole section of rope, the method described in Annex B can be used,
subject to agreement between the parties involved.
This International Standard also provides a method for measuring water repellency, lubrication and finish
content, and heat setting treatment, when requested by the customer.
