12、technical 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 procedures for electronic components, and by
13、the grant of an internationally recognized Mark, or Certificate, of Conformity. The com- ponents produced under the System are thereby acceptable in all member countries without further testing. This detail specification should be read in conjunction with the current regulations for the CECC System.
14、 At the date of printing of this specification the member countries of the CECC are Aus- tria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom, and copies of it can be obtained from the addresses shown o
15、n the blue fly sheet. P R E FACE This detail specification was prepared by CECC WG 25: LF connectors. It is based on DIN 43652 Part 1 to 3, December 1985. It covers a range of high-density rectangular connectors with round removable crimp contacts intended for use in industrial installations for con
16、nection or termination of sub-assemblies or components in electrical equipments or in measuring, regulating and control circuits, equipment for power supply and other electronic devices em- ploying similar techniques. The text of this detail specification was circulated to the members of CECC WG 25
17、and was approved for publication under the accelerated procedure for the acceptance of detail specifications in accordance with Decisions 1 O, 11 and 12 of the minutes of the CECC CD meeting in document CECC(Secretariat)l838.
