FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61300-2-4 has been prepared by subcommittee 86B: Fibre optic

interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.

4 General description

The device under test (DUT) is rigidly clamped to a holding fixture, which is shown in Figure 1,

and a tensile load is applied to the fibre, cord or cable. Potential failure modes for this test

include, but are not limited to:
a) cable sheath damage;
b) strength member damage;
c) fibre breakage or damage;
d) cable clamp failure;
e) cable pull-out;
f) loss of optical continuity or loss of sealing of enclosures;
g) change in optical characteristics, such as attenuation or return loss;

h) breaking, excessive movement or damage to the cable sheath, seals, cable clamps.

5 Apparatus
5.1 Mandrel

The diameter D of the mandrel is equal to the greater of 60 mm or 25 times the diameter d of

the fibre, cord or cable. Use an adequate number of turns to prevent slippage. For optical

components, the distance A between the rearmost portion of the cable fixing component of the

DUT and the mandrel tangent point shall be 200 mm ± 50 mm. For closures, the distance A

shall be the greater of 50 times the diameter d of the fibre, cord or cable or 250 mm.

IEC 61300-3-28 as appropriate. Refer to the required procedure for details.
6 Procedure
6.1 Preparation of DUTs

Prepare the DUTs in accordance with the manufacturer’s instructions or as specified in the

relevant specification. DUTs shall be terminated with a sufficient length of fibre cable to

facilitate interfacing with the optical source and detector.
6.2 Pre-conditioning

Pre-condition each DUT for 2 h for connectors, splices, passive components and fibre

management systems, or for 4 h for closures at the standard atmospheric condition defined in

IEC 61300-1.
6.3 Mounting DUT and visual inspection of the mounted DUT

Securely mount the DUT and its mandrel on the holding fixtures and place in the test

apparatus.

Visually examine each DUT in accordance with IEC 61300-3-1 to ensure that the DUT has not

been damaged by inserting it into the test equipment.
6.4 Initial examination
Visually examine each DUT in accordance with IEC 61300-3-1. Complete the initial

examinations and measurements on the DUT as required by the relevant specification.

For the sealing performance of category S closures, the closure shall be pressurized at the

test temperature. The pressure will be measured at the test temperature in accordance with

test method B of IEC 61300-2-38.

For the optical evaluation, the variation of the attenuation shall be measured in accordance

with IEC 61300-3-3 or IEC 61300-3-28. If required, the attenuation will be measured in

accordance with IEC 61300-3-4.
6.5 Conditioning and optical measurement during the conditioning

Activate the test apparatus so that an axial force is gradually exerted between the DUT and

the mandrel. Apply the load smoothly so as to eliminate any impulse or impact loading effect.

If automatic equipment is used, it is recommended that the load change of the DUT be 5 N/s

for reinforced cable and 0,5 N/s for secondary and primary coated fibre, unless otherwise

specified in the relevant specification. Continue loading until the tensile load specified in the

relevant specification has been reached.

Maintain the specified load for the specified time period required by the relevant performance

specification.
---------------------- Page: 10 ----------------------
IEC 61300-2-4:2019 © IEC 2019 – 9 –

While the DUT is under load, make observations and perform optical measurements when

required by the relevant performance specification.

If required by the relevant specification, measure the change of attenuation in accordance

with IEC 61300-3-3 before, during and after the load is applied.
6.6 Removal of the test load
Remove the test load from the DUT.

For a category S closure, the pressure will be measured at the test temperature in accordance

with test method B of IEC 61300-2-38 before and after applying the load.
6.7 Recovery

Remove the DUT from the test apparatus and allow the DUT to recover under standard

atmospheric condition for 2 h for connectors, splices, passive components and fibre

management systems or for 4 h for closures, as defined in IEC 61300-1, unless otherwise

specified in the relevant specification.
6.8 Final examination and performance check

On completion of the test, perform the final measurements, as defined in the relevant

specification. The results of the final measurement shall be within the limit established in the

relevant specification.

For the sealing test of the DUTs, such as closures, the final sealing performance shall be

checked in accordance with test method A of IEC 61300-2-38.

For the optical evaluation of DUTs, the variation of the attenuation shall be measured in

accordance with IEC 61300-3-3 or IEC 61300-3-28. If required, the attenuation will be

measured in accordance with IEC 61300-3-4.
6.9 Final visual inspection

Visually examine the DUT in accordance with IEC 61300-3-1. Check for evidence of any

degradation in the DUT. This may include, for example:
• broken, loose or damaged parts or accessories, and

• excessive movement of, damage to, or broken cable sheath, seals, or cable clamps.

Repeat the procedure at another test temperature if required.
