Discussion on Electromagnetic Radiation Protection Standard of Light Industrial Equipments
The popular international and Chinese electromagnetic radiation protection standards are introduced, including the ICNIRP guidelines constituted by the International Commission on Non-Ionizing Radiation Protection, the EN62233 standards established by the European Committee for Electrotechnical Standardization and the GB 8702-88 regulations constituted by Ministry of Environmental Protection of the People’s Republic of China, etc. The situation of the light industrial equipments electromagnetic radiation has been tested and analyzed: the power of the induction heater is often up to thousands kilowatts, and there are many electrical control components and many dense circuitries in light industrial equipments. Their complicated electromagnetic fields release continuously electromagnetic waves and engender electromagnetic radiations to the surrounding environment. And, Chinese electromagnetic radiation protection standards lack limits for band less than 100 KHz (except 50Hz). It makes the electromagnetic radiation assessment of light industrial equipments lack sufficient basis. The electromagnetic radiation protection standard of light industrial equipments was discussed and the limits for electromagnetic radiation protection of light industrial equipments are suggested.
