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 61084-2-4 has been prepared by subcommittee 23A: Cable

management systems, of IEC technical committee 23: Electrical accessories.

This second edition cancels and replaces the first edition published in 1996. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

After installation according to the manufacturer’s instructions, a pull force of 100 N ± 2 N is

applied to the means in the most unfavourable direction for 60 s ± 5 s.

During the application of the force, there shall be no stress on insulated conductors.

9.102 Areas of service poles/service posts shall have adequate resistance to vertical load

when both the following conditions are fulfilled.

• These areas are reasonably subjected to vertical load during installation and/or

application. Some areas of service poles or service posts are considered not to be

subjected to vertical load due to their dimensions or shape or height at least 100 mm

above the floor.
• Damage to these areas would impair mechanical or electrical safety.

Compliance is checked by the test of 10.5.103 and, when a resistance to vertical load through

large surface area is declared, by the test of 10.5.104.

9.103 Insulated conductors and/or cables used to connect electrical accessories and/or

communication components in pre-wired service poles/service posts shall be selected in

accordance with the rated voltage of the connected equipment and, in case of electrical

accessories, its rated current.
Compliance is checked by inspection.

9.104 Service poles/service posts placed on the floor declared according to 6.101.2 shall

avoid water coming into contact with insulated conductors and live parts during wet-treatment

of floor by one or a combination of the following methods:

– method 1: ensuring by design that water does not come into contact with insulated

conductors and live parts when the water level is 10 mm above the upper level of the floor

covering;

– method 2: providing manufacturer's instructions which require that insulated conductors

and live parts are positioned not less than 10 mm above the upper level of the floor

covering;
– method 3: providing appropriate sealing.

For method 1, compliance is checked by measurement. For method 2, compliance is checked

by inspection. For method 3, compliance is checked by the following test.

The test is made using the lower part of the service pole/service post fixed on a plywood

board 16 mm thick, with a 50 mm minimum spacing between the sample and the edge of the

support.

Ingress of water is detected by the use of dry absorbent paper positioned between the

plywood board and the sample. The absorbent paper is placed only in areas intended to

accommodate insulated conductors or live parts.

The absorbent paper has a water absorptive height longitudinal of 75 mm per 10 min

according to ISO 535 and a basis weight of 250 g per m according to ISO 536.

The sample is placed carefully into a tray containing water to simulate a mm height of

water on the floor.
NOTE For easy detection of water absorption, coloured water can be used.

After 15 s ± 1 s the sample is removed carefully from the tray and the exterior of the sample is

10 Mechanical properties
This clause of Part 1 is applicable except as follows:
10.2 Cable support test
This subclause of Part 1 is not applicable.
10.3 Impact test
10.3.2 Impact test for installation and application
This subclause of Part 1 is applicable except as follows:
Replacement of the first paragraph by:

The test is carried out with the impact test values declared according to Table 6.

Additional subclauses:

10.3.2.101 The resistance to impact is checked on service poles/service posts including a

flexible component, if any, used to link the service pole/service post to the mounting surface if

the flexible component provides a safety function.

NOTE 1 Examples of safety function are retaining the service pole/service post or relieving conductors from strain

or providing an enclosure.
The test is carried out on an assembly consisting

– for a service pole/service post not longer than 1 000 mm: of a complete service

pole/service post;

NOTE 2 The length to be considered does not take into account the flexible component if any.

– for a service pole/service post longer than 1 000 mm: of one or more sections
1 000 mm ± 5 mm long to simulate the various characteristics (function, design,
material, …) within the service pole/service post.

For service poles/service posts which differ only in length the test is carried out on the

shortest and the longest ones. Other service poles/service posts within the range are deemed

to comply with the requirements for this test.

For a service pole intended for vertical mounting, the test is carried out only on parts of the

service pole which will be lower than 1 500 mm above the floor when installed in accordance

with manufacturer’s instructions.
The assembly includes system components, if any, to simulate normal use.

Before the test, non-metallic system components and composite system components are aged

at the temperature declared according to Table 3 with a tolerance of ±2 °C for 168 h ± 4 h

continuously.

The test is carried out with the impact test values declared according to Table 6.
