It is identical with CENELEC Electronic Components Committee (CECC) 96002:1986 “Harmonized system of quality assessment for electronic components: Blank detail specification: Lever switches”, which is renumbered and retitled by an Erratum as follows: CECC 96200 “H
9、armonized system of quality assessment for electronic components: Sectional specification including blank detail specification: Lever switches”. This standard is being published after ratification but before the Erratum is issued and the necessary changes have been incorporated. This standard is a h
10、armonized specification within the CECC system. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; atte
11、ntion is drawn especially 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. The Technical Committee has reviewed the provisions of CECC 00200 and CECC 00300, to which refere
12、nce is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British
13、Standard does not of itself confer immunity from legal obligations.

19、ed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications a
20、nd 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 specification has been formally appro
21、ved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for Lever Switches. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specification the member co
22、untries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Preface This blank detail specification was prepared by CECC Working Group 24: Switches. It is based, wherever possible,
23、on the publications of the International Electrotechnical Commission. The text of this sectional specification was circulated to the CECC for voting in the document listed below and was ratified by the President of the CECC for printing as a CECC Specification.
