National foreword

This British Standard has been prepared under the direction of the ElectronicComponents Standards Committee. It is identical with CENELEC ElectronicComponents Standards Committee CECC 16101 “ Blank detail specification:

Electromechanical all-or-nothing relays”.

This standard is a harmonized specification within the CECC system.

Terminology and conventions. The text of the CECC specification has beenapproved as suitable for publication, without deviation, as a British Standard.Some terminology and certain conventions are not identical with those used inBritish Standards. Attention is especially drawn to the following.

The comma has been used throughout as a decimal marker. In British Standardsit is current practice to use a full point on the baseline as the decimal marker.

Cross references. The British Standard harmonized with CECC 00100 isBS E9000 “General requirements for electronic components of assessed qualityharmonized with the CENELEC Electronic Components Committee System”Part 1 “ Basic rules”. The British Standard harmonized with CECC 00107 isBS E9000-2 “Rules of procedure”.

The following International Standards are referred to in the text and for eachthere is a corresponding British Standard; these are listed below:

IEC 255 is a multipart standard and relevant parts of it are to be published asidentical British Standards.

Scope. This standard lists the ratings, characteristics and inspectionrequirements which are to be included as the minimum mandatory requirements

in the detail specification for electromechanical all-or-nothing relays conformingto Test schedule 3. It also lists in the inspection schedule those tests which arerecommended for inclusion in the detail specification at the discretion of thespecification writer. These latter tests, if adopted, become a mandatoryrequirement for the detail specification.

The ranking of the test schedules is in accordance with 4.4 of BS CECC 16100.

Detail specification layout. In the event of conflict between the requirementsof this specification and the Provisions of BS E9000 the latter shall takeprecedence except the front page layout will be in accordance with BS 9000Circular Letter No 15 dated August 1977.

Foreword

The CENELEC Electronic Components Committee (CECC) is composed of thosemember countries of the European Committee for ElectrotechnicalStandardization (CENELEC) who wish to take part in a harmonized System forelectronic components of assessed quality.

The object of the System is to facilitate international trade by the harmonizationof the specifications and quality assessment procedures for electroniccomponents, and by the grant of an internationally recognized Mark, orCertificate, of Conformity. The components produced under the System arethereby accepted by all member countries without further testing.

This document has been formally approved by the CECC, and has been preparedfor those countries taking part in the System who wish to prepare and issuenational harmonized detail specifications for ELECTROMECHANICAL

ALL-OR-NOTHING RELAYS. It should be read in conjunction with documentCECC 00100: Basic Rules (1974).

At the date of printing of this document the member countries of the CECC areBelgium, Denmark, Germany, France, Ireland, Italy, the Netherlands, Norway,Sweden, Switzerland, the United Kingdom, and copies of it can be obtained from

the National Committees of the CENELEC in these countries.

Preface

This blank detail specification was prepared by CECC Working Group 16:“Relays”.

It is one of a series of blank detail specifications for electromechanicalall-or-nothing relays, all relating to the sectional specification printed asCECC 16100.

In accordance with the requirements of document CECC 00100 it is based,wherever possible, on the Recommendations of the InternationalElectrotechnical Commission.

The text of this blank detail specification was circulated to the CECC for votingin document CECC(Secretariat)645 in August 1977 and was ratified by theCECC for printing as a CECC Specification.
