The European Commission's non-food rapid warning system issues consumer warnings on Chinese-made laser processing machinery. The notifying country of the case is Germany, and the style / model of the laser cutting machine and engraving machine involved is SH-G 350; the OECD Portal Category is 82000000 (tools / equipment with power supply).
The report pointed out that this laser processing machine belongs to the fourth category of laser products, but there is no corresponding protective device, which is likely to cause burns. In addition, this product does not provide a manual in the Chinese language, and it lacks certain warning words and icons. There is a certain danger and it does not meet the European Machinery Directive 2006/42 / EC and the relevant standard EN11553. At present, the German authorities have taken bans on the product and related measures.
In this regard, the inspection and quarantine department reminded relevant companies: The classification of laser product hazard levels is a defining index describing the degree of damage caused by the laser system to the human body. (Can cut thick steel plates). Manufacturers must affix warning labels with laser hazard classifications to Class II, III, and IV laser products. Exporters should pay attention to the requirements of different markets for laser products, organize the design and production in accordance with the requirements of the standard, and carry out corresponding warning signs for different types of products to ensure that the products meet the requirements of the importing country.
Laser processing uses a high-power laser beam, which may cause serious damage to the human eye and skin; for example: a helium-neon laser beam of only a few milliwatts directly hits the human eye, and the irradiance and irradiation amount focused on the retina can be Significantly greater than the result of sunlight. Pay particular attention to the reflection hazard of the workpiece. It is understood that the laser emits a laser beam through stimulation, and its intensity is reflected in the laser radiation power. If the laser radiation power is too high, it will cause photochemical and thermal damage to the human body, especially for children who are still developing, Laser radiation may have more serious consequences. China's national standard GB 7247.1-2012 "Laser Product Safety Part 1: Equipment Classification and Requirements" According to the degree of harm from low to high, laser products are classified into the following levels: Class 1, Class 1M, Class 2, Class 2M, Class 3R Type, 3B, 4 types, and each type of laser has marking requirements.

Laser safety protection standards
1.International laser safety protection standards
The International Electrotechnical Commission (IEC) Laser Equipment Technical Committee (TC-76) Laser Radiation Safety Working Group began to discuss standards for laser safety protection as early as the 1970s; the International Electrotechnical Commission officially released the international standard IEC 825 (1984) Product Radiation Safety. Equipment Classification. Requirements and User's Guide "; TC-76 Technical Committee formally issued the international standard IEC 820 (1986)" Electrical Safety of Laser Equipment and Facilities "in 1986.
China, Germany, France, the United States, Britain, Japan and other countries have cited 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 published IEC 825-1 (1993) "International Standard Laser Product Safety Part I" Equipment Classification. Requirements and User's Guide. The United Nations World Health Organization issued the Environmental Hygiene Standard 23 in 1982. "Laser and Light Radiation" sets out the standard for the allowable laser irradiation threshold. 2. China's national standard for laser safety protection GB 7247-87 "Radiation Safety of Laser Products. Equipment Classification. Requirements and User's Guide" issued by the National Bureau of Standards 1987.2.9 and implemented in 1987.10.1; equivalent to the international standard IEC 825 ( 1984). The new national standard GB 7247-1995 has replaced the old standard. National standard GB 10320-88 "Electrical Safety of Laser Equipment and Facilities" was issued on December 30, 1988 and implemented on January 1, 1990;
The Ministry of Health of China issued the national standard GB 10435-89, "Workplace Laser Radiation Hygiene Standard", which was implemented in 1989.10.1; these three laser safety standards are applicable to units and enterprises engaged in manufacturing and using laser processing equipment. In addition, China has also formulated the China Machinery Industry Standard JB / T 5524-91 "Laboratory Laser Safety Rules" 1991.7.16, implemented in 1992.7.1.
| Previous: The rapid development of science and technology laser marking machine has also entered a new stage |
Next: The printing of two-dimensional codes is also very easy to print in batches with ordinary laser marking machines
