International Lightning Protection Standards Overview:
The International Electrotechnical Commission (IEC) established the 81st Technical Committee (IEC-TC81) in June 1980. Its task is to compile technical reports, guidelines or specifications for lightning protection as recommendations or recommendations to various countries and regions in the world. use. After the TC81 Committee issued the first standard, "Lightning Protection for Buildings," in 1990, it successively published a series of lightning protection standards.
The IEC was established in 1906 after the International Electrotechnical Congress held in St. Louis, United States, in September 1904, passed the proposal for the establishment of an international standards organization. Its purpose is to organize, compile and publish standards in electronic and electronics (electronics, magnetics, electromagnetism, electroacoustics, telecommunications, energy production and other electronic technologies), and promote international cooperation to enhance international Mutual understanding.
In the standards published by the IEC, it is clearly stated that in order to promote international unification, all IEC national committees should use IEC standards as the national standards of the country as far as possible. If there are disagreements between the national standards and the IEC corresponding standards, they should be in the country. Description in the standard. The IEC encourages the use of the latest versions of standard documents.
China's lightning protection standards:
China's building lightning protection standard was the earliest: GBJ57-83, in November 1994 by Lin Weiyong IEC61024-1 revised to GB50057-94 "Building lightning protection specifications." This standard is currently the most authoritative standard in China's lightning protection technical standards. It combines the geography, meteorological conditions, economic development level, and continuity of standards that have been used for a long time in the past and is applicable to the lightning protection design of new buildings.
This standard does not apply to the lightning protection design of antenna towers, public television antenna systems, oil tanks, and chemical outdoor devices. However, because of the advanced nature and universality of this standard, it is still cited by design specifications such as communication systems and petrochemical systems.
In China's building lightning protection standard, the protection of the lightning pulse electromagnetic pulse is affected by the first part of the first part of the IEC61312-1 lightning pulse electromagnetic pulse protection, and began to increase the content of LEMP.
In addition, “Oil Tank Design Codeâ€, “Design Guidelines for Lightning Overvoltage Protection Works of Communications Bureau (Station)â€, “Safety Specifications for Lightning Electromagnetic Pulse Protection of Computer Information Systemsâ€, “Technical Specifications for Lightning Protection of Meteorological Observatories (Stations)â€, and “New Generation Weather Technical Specifications for Radar Protection, Specifications for Lightning Protection of Building Electronic Information Systems, Technical Specifications for Lightning Protection Device Detection, Specifications for Lightning Electromagnetic Pulse Protection for Weather Information Systems, and Technical Standards for Antenna Surge Protection Products for Antenna Feeders "Risk hazard risk assessment" and so on have all adopted IEC and ITU technical standards.
China's standards are divided into: the national standard (GB) is a mandatory standard, (GB/T) is not mandatory, also known as voluntary or recommended standards)
Industry standards: DL electronic standards, YD post and telecommunications standards, JB military standard, GA* standards, JT traffic standards, TD railway standards, and industry standards also have voluntary standards such as TB/T.
Local standards: DB, CECS Engineering Association standards.
When certain standards are incompatible and inconsistent with each other, the mandatory standards are the standards
