The National Standardization Management Committee issued the No. 10 announcement in 2011 on July 20, 2011, and approved the issuance of two mandatory national standards. The implementation date is November 1, 2011. The standard code and name are as follows:
GB26755-2011 "Fire-fighting mobile lighting device"
GB26783-2011 "Fire rescue lighting line"
Fire-fighting mobile lighting device is a device that can be carried, towed or illuminated by vehicles for firefighting and rescue missions. It is one of the main fire-fighting rescue aids of firefighting forces, and its quality and performance will be directly Affect the success of fire fighting, life rescue, and disaster relief. In recent years, some manufacturers in China have successively researched, developed, produced and sold the products on the basis of the introduction of technology. However, due to the late start of R&D and production, the lack of uniform standards has resulted in products of various manufacturers having different structural types and performance indicators. Different, and the fire brigade to build the Iron Army has an urgent need for the equipment. The GB26755-2011 "Fire Mobile Lighting Device" released this time is based on extensive reference to the current technical parameters of domestic and foreign products. The standard unifies the classification, model, performance requirements and test methods of fire-fighting mobile lighting devices, and has strong operability. The standard technical content mainly includes illuminance, lifting time, continuous working time, limit performance, bending resistance, working noise, protection level, anti-voltage fluctuation performance, insulation resistance, compressive strength, reliability, weather resistance, mechanical environment adaptability Such performance requirements, expert review believes that reached the international advanced level of similar standards.
The fire rescue lighting line is used by firefighters in performing fire fighting and rescue tasks. The equipment used for on-site escape direction indication is directly related to the personal safety of firefighters in fire fighting and rescue. GB26783-2011 "Fire Rescue Lighting Line" stipulates the definition, model, performance requirements, test methods and inspection rules of fire rescue lighting line, its appearance, luminous brightness, flicker frequency, tensile performance, compression resistance, waterproof performance, The highest surface temperature requirements, explosion-proof performance, continuous working time, etc. have made scientific, reasonable and advanced regulations, and can effectively regulate the production, use, quality inspection and supervision of such products after implementation.
The issuance and implementation of the two national standards have adapted to the development needs of the current fire rescue equipment industry, further strengthen the quality supervision and management of products, promote the promotion and application of new achievements and new technologies, increase the effective supply of fire fighting equipment, and ensure the safety of people's lives and property. Will play an important role.
