Fibre ropes - Determination of certain physical and mechanical properties (ISO 2307:2005)

1.1   This European Standard specifies, for ropes of different kinds, a method of determining each of the following characteristics:
- linear density;
- lay length;
- braided pitch;
- elongation;
- breaking force.
1.2   The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension as per Annex A.
1.3   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.
1.4   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.
NOTE   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.
1.5   This standard 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 2307:2005)

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 Wasserab-stoßung, des Gehalts an Batschmittel und Appretur sowie zum Prüfen der Thermofixierung zur Verfügung.

Cordages en fibres - Détermination de certaines caractéristiques physiques et mécaniques (ISO 2307:2005)

1.1   La présente Norme européenne spécifie, pour les cordages de différents types, une méthode de détermination de chacune des caractéristiques ci-apres :
3 la masse linéique ;
3 la longueur du pas ;
3 la mesure du pas de tressage ;
3 l'allongement ;
3 la force de rupture.
1.2   La masse linéique, la longueur de pas et la mesure du pas de tressage sont déterminées sur un cordage préalablement soumis a une force de traction spécifiée dite force de traction de mesure comme il est indiqué dans l'Annexe A.
1.3   L'allongement correspond a la mesure de l'accroissement de la longueur du cordage lorsque la force de traction a laquelle le cordage est soumis passe d'une valeur initiale (force de traction de mesure) a une valeur égale a 50 % de la force minimale de rupture spécifiée du cordage.
1.4   La force de rupture mesurée est la force maximale enregistrée (ou atteinte) au cours d'un essai de rupture de l'éprouvette, effectué sur une machine d'essai de traction, avec déplacement a 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.
NOTE   Lorsque l'essai du cordage dans son entier n'est pas possible, la méthode décrite dans l'Annexe B peut etre utilisée apres accord entre les parties intéressées.
1.5   La présente Norme propose également une méthode de mesurage de la déperlance, de la teneur en lubrifiant et en appret et du traitement de fixation thermique lorsque la demande en est faite par le client.

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 the European Committee for Standardization (CEN) Technical Committee
CEN/TC 248, Textiles and textile products, in collaboration with Technical Committee ISO/TC 38, Textiles, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 2307:1990), which has been technically
revised.

INTERNATIONAL STANDARD ISO 2307:2005(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;
 braided 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 may 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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1968 apply.
4 Principle
4.1 Calculation of the linear density
The linear density is obtained by measurement of the mass and the length, under a reference tension, of a
conditioned test piece (see Clause 9 and Annex C).
4.2 Measurement of the lay length and braided pitch length
This measurement is taken at the time of application of the reference tension.
4.3 Measurement of the elongation of the rope
This measurement is taken by comparing the lengths of a section of the test piece that has been subjected
successively to
a) the reference tension;
b) a tension equal to 50 % of the minimum specified breaking force for the rope.
4.4 Measurement of the breaking force
This measurement is carried out by increasing the tension in 4.3 b) to the breaking point.
5 Apparatus
5.1 Tensile testing machine, accommodating the assumed breaking force of the rope, which allows a
constant rate of traverse of the moving element in accordance with 9.5 and measurement of breaking force to
an accuracy of ± 1 %.
Different types of tensile testing machines may be used:
 pulley-type grip (“cors de chasse” testing machine);
 testing machine with bollards for eye splices;
 wedge-grip testing machine.
In the case of a “cors de chasse” tensile testing machine, the diameter of the pulleys or catches holding down
the test pieces shall be equal to at least 10 times that of the rope being tested.
In the case of a testing machine with bollards, the diameter of the bollards passing through the eye-spliced
test pieces shall be at least twice the diameter of the rope being tested.
5.2 Balance, allowing measurement of mass to an accuracy of ± 1 %.

6 Sampling
6.1 Sample size
When specified by the purchaser, a lot sample for acceptance testing shall be taken at random in accordance
with 6.4.
6.2 Sample unit
If required, test samples shall be taken from each shipping unit in the lot in the number and the length required
to perform the specified tests. The test samples shall be included in the delivered mass or length.
As an alternative, the manufacturer's production and inspection records may be used, if agreed upon the
purchaser and the manufacturer.
6.3 Composition of the batch to be sampled
Samples shall be taken from a homogeneous batch, i.e. consisting of ropes of the same size and same
dimensions and which have been subject to the same series of manufacturing operations and the same
control procedure.
6.4 Selection of samples
Take N number of samples at random from the batch in accordance with Equation (1):
S
NN= 0,4 (1)
S
where N is the batch size, expressed as the number of 220-m coils.
When the calculated value of N is not a whole number, the number obtained shall be rounded to the nearest
S
whole number.
EXAMPLE 27,5 and 30,35 are rounded to 28 and 30, respectively.
Where N < 1, take one sample length.
S
7 Test pieces
7.1 Length
The test piece shall be of adequate length to give an effective length, L (see 9.2), between terminations
u
which is at least equal to that given in Table 1, when mounted on the tensile testing machine (see Figure 1).

7.3 Taking the test pieces
Take the test piece either from one end of the samples, or from the body of the samples if they are intended to
be cut. Take all necessary steps to prevent unlaying. If necessary, remove slightly unlaid ends.
8 Conditioning
Ropes shall be tested in the ambient atmosphere, except in cases of dispute, when the test piece shall be
placed in the atmosphere specified in ISO 139 for at least 48 h, immediately prior to testing.
9 Procedure
9.1 General
Perform the procedures specified in 9.2 to 9.7 sequentially.
9.2 Initial measurements
Lay the test piece out straight with a slight hand force (not to exceed 20 % of the reference tension) on a flat
surface. Measure the initial length L , in metres, to the nearest millimetre.
0
Mark two “w's” on the test piece, spaced symmetrically with regard to its mid-point, and at a distance apart of
l that is greater than 400 mm.
0
NOTE When L < 400 mm, L and l are measured on a separate test piece, with a length of 400 mm minimum,
u 0 2
following the same procedure; the value l is obtained by applying the appropriate tension by means of weights and a
2
pulley.
Determine the mass, m, expressed in grams, of the test piece to the nearest 0,5 %.
An alternative method for ropes sizes greater than reference number 70 is given in Annex C.

9.3 Mounting the test piece on the testing machine
Fix the ends of the test piece onto the machine in order to obtain the effective length of test piece specified in
7.1.
In the case of a test on splices, the eyes shall have a minimum internal length of 6 times the rope diameter
when closed; their production is left to the manufacturer's discretion.
In the case of man-made fibre ropes, it is recommended that the ends of the splices be tapered to finish.
Outside the segment l , mark two “r's” on the test piece delimiting the section in which a rupture is considered
0
as normal, as shown in Figures 1 to 3.
The distance from each mark “r” to the end of splice (or to the tangent point in the case of a “cors de chasse”)
shall be a minimum of two times the diameter and a maximum of three times the diameter of the rope.
