- Scope
- GB 7247.1 applies to the safety of laser products. For convenience, this standard is divided into three independent chapters: Part I (General Rules) and Appendix, Part II (Manufacturing Requirements), and Part III (User Guide). A laser product can be a single laser with or without a separate power supply, or it can be a complex optical, electrical or mechanical system incorporating one or more lasers. Laser products are generally used for the demonstration of physical and optical phenomena, material processing, data readout and storage, information transmission and display, etc. These systems have been used in industry, commerce, entertainment, research, education and medicine. However, laser products sold to other manufacturers for use as part of any system need not comply with this standard, as the end product itself will be subject to this standard. The term "laser" used in this standard includes LEDs (light emitting diodes) whenever possible. Laser products or LED products that meet the following conditions do not need to consider the requirements of this standard, if: - The manufacturer indicates that under all working, maintenance, inspection and failure conditions, according to the classification in Chapter 3, Chapter 8 and Chapter 9 An AEL whose emission level does not exceed class l; - does not contain embedded lasers or embedded LEDs. In addition to the hazards caused by laser radiation, laser equipment can cause other injuries, such as fire and electric shock. This standard states the minimum requirements if the laser system forms part of the equipment, and the equipment must comply with national or IEC safety standards [such as medical equipment (IEC 60601-2-22), information technology equipment (GB 4943), audio and video equipment (GB 8898 ), equipment used in harmful environments], in addition to product safety standards, the equipment should also meet the safety requirements of this standard for laser products. However, if the laser system can be operated independently after being removed from the equipment, the removed unit shall comply with the requirements of this standard. If there is no applicable product safety standard, GB 4793.1 shall be used. The MPE (Maximum Permissible Exposure) value of this standard is only for laser radiation and does not apply to accompanying radiation. However, if a business has a hazardous accessible accompanying radiation, the MPE value for laser radiation can be used to make a careful assessment of that hazard. MPE values do not apply to laser irradiation for medical treatment of patients. Note: Appendices A to D include general guidance and list many typical examples. The appendices must not, however, be considered definitive or exhaustive, but rather serve as references for the corresponding clauses in Parts I through III.
