Components 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 been

approved as suitable for publication, without deviation, as a British Standard Some terminology and certain conventions are not identical with those used in British Standards Attention is especially drawn to the following.

The comma has been used throughout as a decimal marker In British Standards

it is current practice to use a full point on the baseline as the decimal marker.

Cross references The British Standard harmonized with CECC 00100 is

BS E9000 “General requirements for electronic components of assessed quality

harmonized with the CENELEC Electronic Components Committee System”

Part 1 “Basic rules” The British Standard harmonized with CECC 00107 is

BS E9000-2 “Rules of procedure”.

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

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

Scope This standard lists the ratings, characteristics and inspection

requirements which are to be included as the minimum mandatory requirements

in the detail specification for electromechanical all-or-nothing relays conforming

to Test schedule 3 It also lists in the inspection schedule those tests which are recommended for inclusion in the detail specification at the discretion of the specification writer These latter tests, if adopted, become a mandatory requirement 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 requirements

of this specification and the Provisions of BS E9000 the latter shall take precedence except the front page layout will be in accordance with BS 9000 Circular Letter No 15 dated August 1977.

The object of the System is to facilitate international trade by the harmonization

of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity The components produced under the System are thereby accepted by all member countries without further testing.

This document has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to prepare and issue national harmonized detail specifications for ELECTROMECHANICAL ALL-OR-NOTHING RELAYS It should be read in conjunction with document CECC 00100: Basic Rules (1974).

At the date of printing of this document the member countries of the CECC are Belgium, 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.

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

Electrotechnical Commission.

The text of this blank detail specification was circulated to the CECC for voting

in document CECC(Secretariat)645 in August 1977 and was ratified by the CECC for printing as a CECC Specification.
