Область применения
This standard applies to fire hoses used in scenarios such as fire extinguishing and rescue, fixed facilities, and water supply and drainage. It covers Type I, Type II, and Type III fire hoses. It is mandatory for manufacturers producing fire hoses for the Chinese market. Hoses for municipal, garden, agricultural, and marine applications may refer to this standard.
Технические требования
GB 6246-2026 specifies the model designations, basic parameters, and comprehensive performance requirements for fire hoses. Key technical requirements include design working pressure, burst pressure, and dimensional tolerances for inner diameter and length. The standard also mandates specific limits for unit length mass, elongation rate, and expansion rate under hydraulic pressure. Furthermore, it outlines critical performance criteria such as adhesion strength, abrasion resistance, low-temperature resistance, and thermal resistance (both conductive and radiant). Manufacturers must ensure compliance with all specified physical and mechanical properties to guarantee product safety. Additional requirements cover the optical performance of reflective strips and the connection performance between the hose and fire fittings, referencing GB 12514.
Методы испытаний
The standard details rigorous testing procedures to verify compliance. Key tests include the pressure resistance test to determine burst pressure, the adhesion strength test following GB/T 12833-2006, and the abrasion resistance test using specific friction machines. Environmental durability is assessed through low-temperature exposure, thermal aging, and UV light exposure tests. Engineers must follow these standardized testing methods to validate product performance accurately.
Частые вопросы
What products are regulated under GB 6246-2026?
GB 6246-2026 regulates fire hoses used in fire rescue, fixed facilities, and water supply/drainage, categorized into Type I, Type II, and Type III based on their application and diameter.
Are there any updates from the previous version of GB 6246?
