It is identical with CENELEC Electronic Components Committee (CECC)22110:1982 “Harmonized system of quality assessment for electronic components: Sectional specification: Radio frequency coaxial connectors, Series SMA”. This standard is a harmonized specification within the CECC system and will e

Terminology and conventions. The text of the CECC specification has been approved
10、as suitable for publication as a British Standard without deviation. 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 cur
11、rent practice to use a full point on the baseline as the decimal marker. Cross-references. The British Standard harmonized with CECC00100 is BS9000 “General requirements for a system for electronic components of assessed quality” Part 1 “Specification of basic rules and rules of procedure”. There is
12、 no corresponding British Standard for CECC00400. The Technical Committee has reviewed the provisions of CECC00400:1977 to which reference is made in the text and decided that they are acceptable for use in conjunction with this standard. A related British Standard to IEC169-15:1979, referred to in

23、untries 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 and quality assessment
24、 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 be
25、en prepared for those member countries taking part in the System who wish to issue national harmonized specifications for RADIO FREQUENCY COAXIAL CONNECTORS AND ACCESSORIES. It should be read in conjunction with document CECC00100: Basic Rules (1974). Preface This sectional specification was prepare
26、d by CECC Working Group22: RF Connectors. In accordance with the requirements of document CECC00100, it is based, wherever possible, on the Recommendations of the International Electrotechnical Commission and in particular on IEC169-15:1979: Radio frequency connectors, Part 15: R.F. coaxial connecto
27、rs with inner diameter of outer conductor4,13mm (0,163in) with screw coupling Characteristic impedance50ohms (Type SMA). This sectional specification and its associated blank detail specification(s) are specific to Series SMA radio frequency connectors and their related accessories. The connectors c
28、overed by it are intermateable with connectors according to: The mating face and gauging information are taken from IEC169-15. Document numbering for R.F. connector specifications differs from that prescribed by Section3 of CECC00400, in order to permit the issue of more than nine sectional specific
29、ations. The approved numbering system applicable to R.F. connector specifications is illustrated by the diagram on pageiv.
