FIBRE OPTIC INTERCONNECTING
DEVICES AND PASSIVE COMPONENTS –
BASIC TEST AND MEASUREMENT PROCEDURES –
Part 2-9: Tests – Shock
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 nongovernmental 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 61300-2-9 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2010. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) inserted clause "Terms and definitions";
b) added precise descriptions to clause "Apparatus";
c) added sub clause "Testing" into clause "Procedure";
d) added "Bibliography".

3.1
check point
point located on the fixture, on the table surface of the shock machine, or on the DUT as
close as possible to the fixing point and rigidly connected to it
Note 1 to entry

A number of check points may be used to ensure the test requirements are satisfied.

Note 2 to entry If the DUT is attached by more than four fixing points, the relevant specification should state the
number of fixing points that are to be used as check points.

Note 3 to entry In special cases, for example, for large or complex DUTs, the check points will be prescribed by
the relevant specification.
Note 4 to entry If a small DUT is mounted on one fixture or a large number of small DUTs are mounted on one
fixture, or where there are a number of fixing points, a single check point (that is the reference point) may be
selected for the derivation of the control signal. This signal is then related to the fixture rather than to the fixing
points of the DUT(s). This procedure is only valid when the lowest resonance frequency of the loaded fixture is well
above the upper frequency of the test.

3.2
fixing point
point on the DUT in contact with the fixture (Figure 1a) or the table of the shock machine at a
location where the DUT is normally fastened in service
Note 1 to entry If a part of the real mounting structure is used as the fixture, the fixing points are taken as those

where the real mounting structure contacts the table (Figure 1b) and not where the product contacts the real
mounting structure.

General description

A device under test (DUT) is mounted on the table of the shock machine and is subjected to
half-sinusoidal shock pulses. The DUT is exposed to two or three shock pulses applied in
each direction of three mutually perpendicular axes in accordance with severities (see
Clause 7).
Wherever possible, the severity of the pulse applied to the DUT should be such as to
reproduce the effects of the actual transport or operational environment to which the DUT will
be subjected, or to satisfy the design requirements. The DUT is always mounted to the fixture
or the table of the shock machine during testing.

Shock machine

5.1.1

General

The shock machine may be of the free fall, resilient rebound, nonresilient, hydraulic,
compressed gas or other activating type. The shock machine shall be capable of generating a
calibrated acceleration when loaded with a DUT, with or without a fixture. The shock machine
shall be capable of generating a half-sinusoidal excitation measured at the checkpoints, within
the tolerance shown by the solid lines in Figure 2.

5.1.2

BS EN 61300-2-9:2017
IEC 61300-2-9:2017 © IEC 2017

Repetition rate

The repetition rate shall be such that the relative motion within the DUT between shocks shall
be substantially zero and the value of acceleration at the check point shall be within the limits
shown in Figure 2.
5.1.3

Velocity change tolerances

For all pulse shapes, the actual velocity change shall be within ±15 % of the value
corresponding to the nominal pulse.
Where the velocity change is determined by integration of the actual acceleration pulse, this

shall be effected from 0,4 D before the pulse to 0,1 D beyond the pulse, where D is the
duration of the nominal pulse.
If the velocity change tolerance cannot be achieved without the use of elaborate facilities, the
relevant specification shall state the alternative procedure to be adopted.
5.1.4

Cross axis motion

The positive or negative peak acceleration at the check point(s), perpendicular to the intended
shock direction, shall not exceed 30 % of the value of the peak acceleration of the nominal
pulse in the intended direction, when determined by 5.1.5.
If the cross axis motion tolerance cannot be achieved, the relevant specification shall state
the alternative procedure to be adopted.
5.1.5

Acceleration measuring system

The characteristics of the measuring system shall be such that it can be determined that the
true value of the actual pulse, as measured above, in the intended direction at the
checkpoint(s) is within the tolerances required by Figure 2.
The requirements of Figure 3 apply to the frequency response of the measuring system
without the use of a low-pass filter on the control signal. When a low-pass filter is used, the
characteristics of the filter should be such that its cut-off frequency fg (–3 dB point) is not
lower than:
fg =

1,5
D

where

fg is the cut-off frequency of a low-pass filter in kHz;
D is the duration of nominal pulse in ms.
The frequency response of the overall measuring system, which includes the accelerometer,
can have a significant effect on the accuracy and shall be within the limits shown in Figure 3
and Table 1.

The DUT shall be prepared and mounted with accessories as specified in the relevant
specification and fastened to the table of the shock machine.
5.3

Optical power measuring equipment

Unless otherwise specified, measuring equipment specified in IEC 61300-3-28 shall be
connected to the DUT for monitoring the transient loss to detect fast variation of attenuation.

Prepare the DUT according to the manufacturer´s instructions or as specified in the relevant
specification.


– 10 –
6.2

BS EN 61300-2-9:2017
IEC 61300-2-9:2017 © IEC 2017

Pre-conditioning


Pre-condition the DUT for 2 h at the standard atmospheric condition specified in IEC 61300-1
unless otherwise specified in the relevant specification.
6.3

Initial examinations and measurements

Complete initial examinations and measurements of the DUT as required by the relevant
specification.
6.4

Testing

The DUT shall be mounted rigidly to the fixture in a manner that simulates normal mounting
as closely as possible. A minimum length of 200 mm of optical fibre/cable shall be
unsupported on both ends of the DUT and be attached free of tension to the table of a shock
machine. Conduct the procedure as outlined in 6.5 and 6.6.
The number of shocks prescribed by the relevant specification shall be applied successively
in each direction of three mutually perpendicular axes of the DUT. When testing a number of
identical DUTs, they may be oriented so that the shocks are applied simultaneously along
these three axes (see Clause 7).
Where the position of the DUT, when mounted or transported, is known, and since shocks are
generally of greatest significance in one direction of one axis, the relevant specification shall
state the specified number of shocks that shall be applied and in which axis, direction and
position. Otherwise, three axes and two directions shall be tested. For example, usually the
highest levels of shock acceleration are along the vertical axis. When the position during
transportation is known, the shocks should be applied in what will be the vertical axis in the
upward direction. Where the position is unknown, the specified number of shocks shall be
applied in each of the axes prescribed by the relevant specification (see Clause 7).
The relevant specification shall state whether the DUT shall operate during testing and if any
functional monitoring is required.

6.5

Recovery

Allow the DUT to remain on the fixture for 1 min unless otherwise specified in the relevant
specification.
6.6

Final examination and measurements

On completion of the test, remove all fixtures, clean the DUT in accordance with the
manufacturer’s instruction and inspect the DUT and make final measurements as defined by
the relevant specification, to ensure that there is no permanent damage to the DUT. The
relevant specification shall provide the criteria upon which the acceptance or rejection of the
DUT shall be based.
Unless otherwise specified, 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 and/or accessories,

•

broken or damaged cable sheath, seals, strain relief or fibres, and

•

displaced, bent, broken or damaged parts.

Storing and using standards
Standards purchased in soft copy format:
• A British Standard purchased in soft copy format is licensed to a sole named
user for personal or internal company use only.
• The standard may be stored on more than 1 device provided that it is accessible
by the sole named user only and that only 1 copy is accessed at any one time.
• A single paper copy may be printed for personal or internal company use only.
Standards purchased in hard copy format:
• A British Standard purchased in hard copy format is for personal or internal
company use only.
• It may not be further reproduced – in any format – to create an additional copy.
This includes scanning of the document.
If you need more than 1 copy of the document, or if you wish to share the
document on an internal network, you can save money by choosing a subscription

product (see ‘Subscriptions’).
