Laser safety protection standards

International Laser Safety Protection Standards The International Electrotechnical Commission (IEC) Laser Equipment Technical Committee (TC-76) Laser Radiation Safety Working Group began to discuss laser safety protection standards as early as the 1970s; 　　 International Electrotechnical Commission officially issued the international standard IEC 825 in 1984 (1984) 'Radiation Safety of Laser Products. Equipment Classification. Requirements and User Guide'; TC-76 Technical Committee officially issued the international standard IEC 820 (1986) 'Electrical Safety of Laser Equipment and Facilities' in 1986.　　 Now, China, Germany, France, the United States, Britain, Japan and other countries all quote this international standard. In September 1993, the International Electrotechnical Commission issued IEC 825-2 (1993) 'International Standard Laser Product Safety Part II Optical Fiber Communication System Safety'; later it issued IEC 825-1 (1993) 'International Standard Laser Product Safety Part One' Equipment Classification, Requirements and User Guide' 　　 The United Nations World Health Organization issued Environmental Health Standard 23 in 1982, 'Laser and Light Radiationmy country's laser safety protection standard national standard GB 7247-87 'Radiation safety of laser products. Equipment classification, requirements and user guideThe new national standard GB 7247-1995 has replaced the old standard. The national standard GB 10320-88 'Electrical Safety of Laser Equipment and Facilities' was issued on December 30, 1988 and implemented on January 1, 1990; 　　 my country’s Ministry of Health issued on February 24, 1989, the national standard GB 10435-89 'Laser Radiation Hygiene Standard for Workplaces' on October 1989. .1 Implementation; 　　 These three laser safety standards are applicable to units and enterprises engaged in the manufacture and use of laser processing equipment. In addition, my country has also formulated the Chinese machinery industry standard JB/T 5524-91 issued on July 16, 1991, and implemented on July 1, 1992.
