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 (see www .iso .org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

4 Principle
4.1 Calculation of the linear density

The linear density is obtained by measurement of the mass and the length, under the reference tension

specified in Annex A, of a conditioned test piece.
4.2 Measurement of the diameter, lay length and braid pitch

These measurements are 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 (this length is called l , see Figures 1, 2 and 3), and

b) a tension equal to 50 % of the minimum specified breaking force for the rope. Alternatively,

additional elongation measurements may be made in increments of, for example, 10 % tension,

from 10 % to 50 % of the minimum specified breaking force of the rope. See 9.6 for procedures and

safety recommendations.
4.4 Measurement of the breaking force

This measurement is carried out by increasing the maximum tension achieved in 4.3 b) to the

breaking point.

Alternatively, the methods described in Annex B can be used, subject to agreement between the parties

involved. In such case, a mention shall be made in the test report that the breaking strength was

calculated from yarn test results
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 the

breaking force to an accuracy of ±1 %.

The stroke and bed length should be long enough to extend the specimen to rupture in one

continuous pull.

NOTE In case a specimen is pulled to break to rupture in more than one pull, the result can be affected.

Different types of tensile testing machines may be used:
— bollard-type grip testing machine;
— testing machine with pins for eye splices;
— wedge-grip testing machine.

In the case of a bollard-type tensile testing machine, the diameter of the bollard or capstan 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 pins, the diameter of the pins passing through the eye-spliced test

pieces shall be of an adequate size so that the rope does not break in the eye, in principle 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 Composition of the batch to be sampled

Samples shall be taken from a homogeneous manufacturing 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.

If additional information is required, test samples shall be taken from each shipping unit (manufacturing

batch), with the necessary characteristics to perform the specified tests. The 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

between the purchaser and the manufacturer.
6.2 Sample size

Batch samples for acceptance testing shall be taken at random in accordance with 6.3 or as per a

sampling plan defined and accepted by both the purchaser and the manufacturer.
6.3 Selection of samples

Take the number N of samples at random from the batch in accordance with Formula (1):

NN=04, (1)

where N is the batch size, expressed as the number of continuous lengths or coils.

NOTE A typical coil size is 220 m.

When the calculated value of N is not a whole number, the number obtained shall be rounded to the

nearest whole number.
EXAMPLE 27,5 and 30,35 are rounded to 28 and 30, respectively.
Where N < 1, take one sample length.
7 Test pieces for tensile testing and force-elongation measurements
7.1 Length

The test piece shall be of adequate length to give an effective length, L (see 9.3), between terminations

which is at least equal to 5 pitches or lays or 400 mm, whichever is greater.
7.2 Number of test pieces
Take one test piece from each sample.
7.3 Taking the test pieces

7.3.1 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.

An alignment line should be marked along the rope specimen surface, parallel to its axis, using a suitable

marking device. When the rope specimen is mounted on the test bed, it shall be arranged such that the

marked line is straight.

---------------------- Page: 15 ----------------------
SIST EN ISO 2307:2019
ISO 2307:2019(E)

7.3.2 When testing the rope on pins, eye splices shall be made in accordance with the rope

manufacturer’s instructions. In case of a deviation of the manufacturer’s instructions, the result can be

different. The splice method used shall then be documented with the report. The splice shall be suitable

for general rope service and should not be a special design intended to enhance performance during

testing.

Eye splices shall be of sufficient size that the rope does not break in the eye. In principle, the eyes shall

have a minimum internal length of 6 times the rope diameter when closed.
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

For the measurement of force-elongation and breaking force, perform the procedures specified in 9.2 to

9.7 sequentially.
For the linear density, perform the procedures specified in Clause 10.
9.2 Initial measurements

Lay the test piece out straight on a flat surface by pulling with a slight force of the hand (not exceeding

20 % of the reference tension) (see Annex A).

Make two “w” marks 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.

In exceptional circumstances, when L < 400 mm, l and l (see 9.4) are measured on a separate test

u 0 2

piece, with a minimum length of 400 mm, following the same procedure; the value l is obtained by

applying the appropriate tension by means of weights and a pulley.
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 the test piece

specified in 7.1.

Outside the segment l , make two “r” marks on the test piece, delimiting the section in which a rupture

is considered as normal, as shown in Figures 1 to 3.

The distance from each mark “r” to the end of the splice (or to the tangent point in the case of a bollard)

shall be a minimum of twice the diameter and a maximum of three times the diameter of the rope.

For testing a sample with a braider splice (see ISO 9554:2019, 4.4.3), the marked braider splice shall be

located in the middle of the test specimen, with a minimum of 400 mm of undist
