Part 6 : fnformation to be given with enquirieso enders and ordersand rules for transport, erection and maintenance

FOREWORD

I ) The formal decisions or agreements of the I E C on technical matters, prepared by Technical Committees on which all theNational Committees having a special interest therein are represented, express, as nearly as possible, an internationalconsensus of opinion on the subjects dealt with.

They have the form of recommendatiot-ts or international use and they are accepted by the National Committeesin thatsense.

In order to promote this international unification, the I E C expresses he wish that all National Committees having asyet no national rules, when preparing such rules, should use he I E C recommendations as the fundamental basis or theserules n so far as nat ional condi t ions wil l permit .

4) The desirability is recognized of extending international agreement on these matters through an endeavour to harmonizenational standardization rules with these recommendations in so far as national conditions will permit. The NationalCommittees pledge their influence towards that end.

PREFACE

This Recommendation has been prepared by Sub-Committee 17A,Technical Committee No. 17, Switchgear nd Controlgear.

Switchgear and Controlgear, of IEC

A f irst draft was discussed at the meeting held in Arnhem in 1968. As a result of this meeting a final draft was submittedto the National Committees for approval under the Six Months' Rule in January 1970.

This Publication forms part of the revision of IEC Publication 56 and includes Section One - Information to be givenwith enquiries, tenders and orders, and Section Two - Rules for transport, erection and maintenance.

The following countries voted explicitly in favour of publication:

Australia NetherlandsBelgium NorwayCanada PolandCzechoslovakia RomaniaDenmark South AfricaFinland SwedenFrance SwitzerlandGermany TurkeyIran Union of SovietIsrael Socialist RepublicsItaly United KingdomJapan United States of AmericaKorea (Democratic People's Republic of) Yugoslavia

This Publication has been divided into the following six parts which are published as separate booklets:

Conditions during transport, storage and erection

A special agreement should be made between user and manufacturer if the temperature andhumidity conditions, defined in Clause 2 of IEC Publication 56-1, cannot be guaranteed duringtransport, storage and erection. Special precautions may be es sential or the protection of insulationduring shipment, storage and erection, and prior to energizing, o prevent moisture absorption due,for instance, o rain, snow or condensation. These may include shipment of insulating parts in oi lto prevent contamination. Appropriate instructions should be given.

5. Erection

For each circuit-breaker, the instructions provided by the manufacturer should at least includeitems as isted below.
