I. Introduction 1998 10 14 is the 29th World Standards Day, President of the International Organization for Standardization ISO, IEC and ITU Secretary-General President delivered a speech entitled "Standards in daily life," the speech. Message from that: the standard is a "benchmark", it gives people the criteria for distinguishing a thing, quality measurement based on and compatible and Internet protection. Standard is designed to help and serve the community, help people to enjoy and use the environment without damaging the environment; help shape the lives rather than living out of and do not know; help people secure life without danger; help people to master advanced science and method instead of lagging behind; to help people learn to use the law to protect their legitimate rights and interests without being easily damaged.
Are three world standards organization dedicated to international standardization. IEC (International Electrotechnical Committee) standards promulgated in its preamble are stated: to promote international unification, IEC National Committees of all the greatest extent possible to the IEC standard as to their standards, national standards and IEC standards in the corresponding Any differences should be clearly stated in the national standards. "The People's Republic of China Standardization Law" requirement. "The state encourages adoption of international standards and advanced foreign standards." State Economic Commission, Planning Commission, Science and Technology Commission and the Technical Supervision jointly issued "on promoting use of international standards and foreign advanced standards of a number of provisions" (article No. 532 of 1993) stipulates that: "use of international standards and foreign advanced standards is a Chinese important the technical and economic policy is to promote technological progress, improve product quality, expanding opening up, accelerate and international practice, development of the socialist market economy, an important measure. "
Standards of practice and from scientific research, is the wisdom of millions of workers in science and technology, as technology advances, standards are constantly revised and updated. In the IEC standard are described as follows: At time of publication version is valid, encouraging the use of the latest version of the standard documents. China's national standard is also commonly issued "Revised Order" in the form of the standard changes, or notice issued in the new standards described in the original standard obsolete. Adoption and promotion of international standards is an important low-cost world of technology transfer. The world with most countries, including China, have adopted the principle of equivalent use of the extensive use of international standards, promote national technological progress.
II framework of international standards for lightning protection
Mine preparation of technical standards mainly by the IEC and the ITU (ITU, formerly known as CCITT) to conduct, under the agreement in close collaboration with IEC and ISO. National Electrotechnical Commission (IEC National Committees) to participate in IEC standardization of electrical and electronic fields of international cooperation, and fulfill their obligations to IEC standard equivalent (eqv) or equivalent (idt) adopted national standards for the country.
The earliest work of international technical standards for lightning protection is IEC/TC81 (Technical Committee 81 mine) started in 1980, the initial goal is to develop standards and guidelines for building mine. China is a 25 P members (Participatingmembers), an active part in the work, take a vote on the draft standard obligations, countries participating in the meeting as possible. Mr. Lin Weiyong as the representative of China attended the 1992 conference, currently participate in the revision of IEC1024-l. As electronic devices suffer
the Lightning (standard in the atmosphere has often said over-voltage) and switching over-voltage (power input or the removal, also known as operating over-voltage) losses growing by the IEC Central Office in coordination Some TCSI experts to join the IEC other committee work, while other committee of experts was invited to join the TCSI work of the Commission so that all of science and technology to penetrate each other, because the workload of the different emphasis, in the promulgation of technical standards for lightning protection on the outside by the addition TC81 , related there TC64, TC37, TC77 Electrical installations of buildings issued, over-voltage protection devices, electromagnetic compatibility
