IEC Foreword
1) The formal resolutions or agreements of IEC (International Electrotechnical Commission) on technical issues are formulated by technical committees participated by national committees with special concerns about these issues, and represent the international consensus on the issues involved as much as possible. 2) These resolutions or agreements are used internationally in the form of recommended standards and are recognized by national committees in this sense. 3) In order to promote international unification, IEC hopes that national committees will adopt the text of IEC standards as their national standards if the conditions in their own countries permit. The differences between IEC standards and corresponding national standards should be indicated in the national standards as much as possible. GB/T4210—2001
IEC Preface
This vocabulary is part of the international standard IEC60050 "International Electrotechnical Dictionary" (IEV), which is Chapter 581: Electromechanical components for electronic equipment.
The first draft was revised by TC48 Electromechanical components for electronic equipment in Leningrad in September 1971, and it was decided to solicit opinions according to the six-month rule.
Subsequent revisions were revised by Working Group 1 of TC48 during the LasPalmas meeting, and the new draft was solicited for comments in May 1972.
At the Geneva meeting in October 1972, Working Group 3 of TC48 revised this standard and accepted the opinions of the Canadian, German and Swedish National Committees, which have been considered and necessary editorial changes have been made. The final draft was voted in February 1975 according to the six-month rule.
A draft containing additional terms and definitions was submitted to TC48 for comment. Comments received were discussed in London in 1973 and it was decided to submit comments according to the June rule. This standard was approved in July 1976. It was finally decided that the original draft and the additional terms should constitute Chapter 581 of IEV. The TC48 Editorial Committee and the Secretary General of TC1 jointly carried out the necessary editorial work and revisions. This chapter contains only terms related to the technical scope of TC48. General and specialized terms listed in other standards are not included in this chapter. The following countries voted to approve this standard.
