20、, (c) BSI EN 196000:1992 BSI 26 April 20022 Foreword The CENELEC Electronic Components Committee (CECC) is composed 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 qu
21、ality. 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
22、 are thereby acceptable in all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for ELECTROMECHANICAL SWITCHES. It should be re
23、ad in conjunction with the current regulations for the CECC System. At the date of printing of this specification, the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Ki
24、ngdom, and copies of it can be obtained from the addresses shown on the blue fly sheet. Preface This generic specification was prepared by CECC WG 24: Switches and sensors. It is based, wherever possible, on the Publications of the International Electrotechnical Commission. The text of this Issue 2
25、consists of the text of CECC 96000 Issue 1 (1985) amended in accordance with the ratified new material introduced in the following documents: Effective date This Issue 2 shall become effective for all new applications for qualification approval on 20 February 1992. Issue 1 shall remain valid to cove
