key words: Untitled Document of emergency lighting fire protection design product selection of the sixth sub Technical Committee of the National Fire Protection Standardization Technical Committee. The sixth sub Technical Committee of the National Fire Protection Standardization Technical Committee held three sessions of five meetings in Wenzhou, Zhejiang Province from 26 to 27 October. Members of the Third Committee of the sixth sub committee, communication members and invited representatives attended the meeting. The meeting heard and considered the work report of the sixth sub committee from 2003 to 2004 and the key points of the work plan from 2004 to 2005, reviewed 13 drafts of national standards for examination, and held the 12th academic seminar of the sixth sub committee. The participants fully affirmed the achievements of the standardization work of the sixth sub committee. It conveyed and studied the document on the important measures and spirit of strengthening China's fire protection standardization proposed at the first session of the Fourth National Fire Protection Standardization Technical Committee this year. It reiterated and clarified the content and significance of the fire safety standards newly issued and being formulated in China, as well as the progress of activities and work such as international exchange of fire standardization technology and comparative research on fire standardization at home and abroad. During the meeting, the participating members reviewed and passed 13 standards, including the requirements and methods of preventive detection of building electrical fire in national standards. It has a strong practical guiding significance for China's building fire prevention to standardize fire cause identification and investigation, emergency lighting, fire protection design, product selection and construction acceptance from the source. 1、 The national standard building electrical fire preventive detection requirements and Law (Draft for approval) stipulates the power supply and distribution devices, low-voltage distribution equipment, power distribution. Below, the technicians of Jinan new era Gold Testing Instrument Co., Ltd. have compiled a detailed procedure for the use of the experimental machine. The contents, requirements, methods and system corresponding terms of the fire safety inspection and test of electrical devices such as lines, low-voltage electrical equipment, grounding and equipotential bonding Fire hazard level and fire hazard category, etc. This standard refers to the international standard iecl electrical installations of buildings, Part 6-6, transaction price unpublished, Part 1: preliminary inspection, IEC electrical installations of buildings, Part 4: safety protection, Chapter 48: selection of protective measures according to external influences, Section 482 fire protection, national standard gbl6895.1, positive c60364-1 electrical installations of buildings, Part 1: scope, purpose and basic principles, GB 16895.6, Iec60364-5-52 electrical installations of buildings Part 5 selection and installation of electrical equipment Chapter 52: wiring system, gb50217 code for design of cables in power engineering, gb50222 code for fire protection design of interior decoration of buildings, gb50303 code for acceptance of construction quality of electrical engineering of buildings, etc., combined with the working experience and implementation status of technical specifications (procedures) for electrical fire protection testing in some provinces and cities of China, The evaluation principles and methods of electrical fire hazard classification are put forward. The formulation and implementation of the standard. It is the first time to standardize the preventive detection of building electrical fire in China. It has a strong guiding significance for improving the quality and level of detection technology. 2、 The national standard fire alarm acceptance system consists of three parts: general performance requirements of fire alarm acceptance information system, fire alarm dispatcher, and fire digital recording device. Among them: fire alarm acceptance system Part l: general performance requirements of fire alarm acceptance information system (Revised Draft for approval) stipulates the scope, general requirements, functional requirements and information requirements of fire alarm acceptance information system. The standard refers to the GB code for the design of fire communication command system, the classification method of urban fire and other disasters and accidents in the National Tenth Five Year Plan, the technical achievements of the preparation technology of fire fighting and rescue force deployment plan, the public security fire forces' implementation of the logistics regulations, and a number of scientific research achievements of the fire communication command system in recent years, It also refers to the design standard of Japanese fire emergency communication dispatching system and the installation, maintenance and use standard of American nfpal22i/02 emergency communication system, and formulates various requirements according to the actual situation of our country. The performance indicators and technical requirements specified in this standard have reached the level of similar international standards. It fills the domestic gap. The national standard fire alarm acceptance system Part 2: fire alarm dispatcher (Revised Draft for approval) stipulates the technical requirements, test methods, inspection rules, signs, instructions, packaging, transportation and storage of fire alarm dispatcher in the fire alarm acceptance system. The standard refers to GB fire communication command system design specifications, public security fire force duty regulations, and a number of scientific research achievements of fire communication command system in recent years. At the same time, various requirements are formulated according to the actual situation of our country. The national standard fire alarm acceptance system Part 3: fire alarm digital recording device (Revised Draft for approval) stipulates the technical requirements, test methods, inspection rules, signs, instructions, packaging, transportation and storage of fire alarm digital recording device in the fire alarm acceptance system. The standard refers to GBS fire communication command system design specifications, public security fire force duty regulations and a number of scientific research achievements of fire communication command system in recent years. At the same time, various requirements are formulated according to the actual situation of our country. The performance indicators and technical requirements specified in this standard have reached the advanced level of similar domestic standards. The revision and implementation of the above three standards constituting the fire alarm acceptance system. It will play an important role in strengthening the industry management of China's fire alarm acceptance information system products, promoting the improvement of product quality and ensuring the safety of people's lives and property. 3、 The national standard technical identification method of trace material evidence in electrical fire scene is composed of four parts: Macro method, remanence method, auger analysis method and metallographic analysis method. These four CMA national quality inspection centers have revised the original standard, adjusted the name, scope of application
