Vtiči in vtičnice za gospodinjstva in podobne namene - 2-4. del: Posebne zahteve za vtiče in vtičnice za SELV (varnostna mala napetost)

Ta del 2-4 IEC 60884 velja za vtiče, fiksne ali prenosne vtičnice, in za vtičnice za aparate od 6 V do vključno 48 V izmeničnega ali enosmernega toka (50/60 Hz) SELV z ocenjenim tokom 16 A, ki so namenjeni za gospodinjstva ali podobne namene, naj si bo v zaprtih prostorih ali zunaj. OPOMBA 1: Razširitev tega standarda na višje frekvence je v obravnavi. Ta standard ne zajema zahteve za vgrezne vgradne doze; zajema samo tiste zahteve za površinske doze, ki so potrebne za preskuse vtičnice. Ta standard prav tako velja za vtiče in vtičnice, vgrajene v kompletih podaljškov električnega kabla ali integrirane ali vgrajene v naprave ali namenjene za pritrditev na njih. OPOMBA 2: Vtičnica, vgrajena v napravo ali opremo, je vtičnica, ki jo oblikuje ohišje naprave ali opreme. Vtičnica, vgrajena v aparat ali opremo, je ločena vtičnica, vgrajena ali pritrjena na aparat ali opremo. Poleg tega, morajo vtičnice za aparate ali opremo biti v skladu z IEC 60884-2-2. Ta standard ne velja za:
- vtiče, vtičnice in spojnike za industrijske namene;
- spojnike za aparate;
- fiksne vtičnice kombinirane z varovalkami, avtomatskimi stikali itd.
Vtiče in fiksne ali prenosne vtičnice, ki so v skladu s tem standardom in so primerne za uporabo pri zunanjih temperaturah, ki običajno ne presežejo 25 C, vendar včasih dosežejo 35 C. OPOMBA 3: Vtičnice, ki so v skladu s tem standardom, so primerne samo za vgraditev v opremo na takšen način in na takšno mesto, kjer okoliška temperatura ne presega 35 C. Na mestih, kjer prevladajo posebni pogoji, kot na ladjah, vozilih in podobno, ter na nevarnih mestih, na primer, kjer je možnost eksplozij, se lahko zahteva posebna izgradnja.

PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD
AND SIMILAR PURPOSES –
Part 2-4: Particular requirements for plugs and socket-outlets for SELV
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 60884-2-4 has been prepared by subcommittee 23B: Plugs, socket-

outlets and switches, of IEC technical committee 23: Electrical accessories.

This third edition cancels and replaces the second edition published in 1999. It constitutes a

technical revision. The main changes from the previous edition are as follows:
Clause 7 – Classification:

– deletion of classification according to the degree of protection against harmful ingress of

water;

– inapplicability of 7.1.3 of Part 1 concerning classification according to the provision for

earthing:

– inapplicability of 7.2.2 of Part 1 concerning classification according to the existence of

shutters.
