No. EN 175100:1992 EEN175100:1992 BSI 12-1999 2 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 ele
17、ctronic components of assessed quality. 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 com
18、ponents produced under the System 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 TWO PART a
19、nd EDGE SOCKET CONNECTORS FOR PRINTED BOARD APPLICATION. It should be read 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 Net
20、herlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Preface This sectional specification (SS) was prepared by CECC WG 25 “Low frequency connectors”. It is based, wherever possible, on the Publication of the International Electrotechnical Commission, and in particular on IE
21、C 512: Electromechanical Components for Electronic Equipment; Basic Testing Procedures and Measuring Methods.

Scope This sectional specification is applicable to connectors particularly designed for use with printed boards in equipment for telecommunication and in electron
28、ic devices employing similar techniques. Connectors essentially designed for use at frequencies exceeding 3 MHz are not covered. The object of this SS is to establish uniform specifications and type test requirements for connectors for printed board applications and to establish rules for the prepar
29、ation of DS. In the event of conflict between this SS and the DS, the requirements of the DS shall prevail.EN175100:1992 6 BSI 12-1999 Section 2.
