IEC Foreword
1) The formal resolutions or agreements of IEC (International Electrotechnical Commission) on technical issues are formulated by technical committees in which national committees with special concerns about these issues participate, and represent the international consensus on the issues involved as much as possible. 2) These resolutions or agreements are published in the form of standards, technical reports or guidelines, and are recommended for international use and, in this sense, recognized by the national committees.
3) In order to promote international unification, each IEC national committee has the responsibility to make its national and regional standards adopt IEC standards as much as possible. Any differences between IEC standards and corresponding national or regional standards should be indicated in the national or regional standards. IEC Introduction
International Standard IEC512-4 was formulated by IEC/TC48 (Electromechanical Components for Electronic Equipment). This standard is Part 4 of the entire set of standards.
This standard is used together with Part 1: General Principles (IEC512-1: 1984). The other test items included in the whole set of standards are given in Appendix A of IEC512-1. These test items are published after they are formulated.
This standard is scheduled to replace the corresponding test items in IEC130-1 "Part 1 of Connectors with Frequencies Below 3MHz: General Requirements and Test Methods".
The draft was discussed at a meeting held in Leningrad in 1971 and formed into documents 48 (CO) 83, 84, 85 and 86, which were sent to various national committees for voting according to the "six-month method" in April 1972. The countries that have approved the issuance of tests 6a, 6b and 6c are as follows: Austria
