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.

IEC 61300-2-10 has been prepared by subcommittee 86B: Fibre optic interconnecting devices

and passive components, of IEC technical committee 86: Fibre optics. It is an International

Standard.

4 General description

The device under test (DUT) is exposed to a static compressive load which is applied by a

pad.
5 Apparatus
5.1 General
Depending on the DUT type, the apparatus consists of:

– for connectors, passive components, hardened connectors and closures (see Figure 1);

– for an evenly distributed static load applied to the top surface of a street cabinet

(see Figure 2 and Figure 3);

– for a static load applied to a street cabinet door (see Figure 4 and Figure 5). The force

shall be applied on top of an open door at the point which creates the highest moment on

the hinge of the door.
5.2 Plate or ground

For the crush apparatus shown in Figure 1, a minimum 10 mm thick plate using steel or

material with comparable hardness, large enough for the whole DUT, or as specified in the

relevant specification, is required. The plate is placed on a non-yielding surface. The plate

has rounded edges.

For the apparatus for an evenly distributed static load applied to the top surface of a street

cabinet shown in Figure 2 and Figure 3 and for a static load applied to a street cabinet door

shown in Figure 4 and Figure 5, the street cabinet shall be fixed securely to firm ground.

5.3 Pad

A pad with a minimum thickness of 10 mm, made of steel or a material with comparable

hardness, and with rounded edges fixed to a non-yielding plate is required. The pad shall

have a diameter of 5,6 cm (equals to a surface of 25 cm ) and contacts the DUT with its flat

circular surface, except for the load test with an evenly distributed static load applied to the

top surface of a street cabinet.
5.4 Force generator

The force generator may be any device or apparatus capable of smoothly applying the

specified load at the specified rate.
5.5 Gauge

The gauge shall be a suitable instrument for measuring the load applied to the DUT.

5.6 Temperature chamber

If the test has to be performed at another temperature than ambient, then a temperature

chamber of appropriate size and a temperature sensing device shall be used. The

temperature chamber shall be able to accommodate the DUT, the pad and the force generator,

and maintain the specified temperature within ± 2 °C.
