Compliance overview
Scope and applicability
This standard applies to fire suction hoses used for extracting water or foam liquid during firefighting and rescue operations. It covers hoses made of rubber and plastic materials, classified into straight and coiled types. It is not applicable to other types of fire hoses or non-firefighting industrial hoses. The standard references GB 12514 for interface performance requirements.
Technical requirements
The standard specifies comprehensive performance criteria for fire suction hoses. Structural and material requirements mandate specific layer compositions for rubber and plastic hoses, ensuring durability and flexibility. Dimensional and mass limits are established for internal diameter, length, and unit length mass to guarantee compatibility and operational efficiency. Pressure and vacuum performance are critical, with defined limits for rated working pressure, test pressure, and burst pressure. Hoses must withstand specified vacuum levels without delamination or collapse. Additionally, the standard sets criteria for bending and flexing performance, ensuring hoses maintain integrity under various load and temperature conditions. Aging resistance is addressed through UV radiation testing for plastic hoses and ozone resistance testing for rubber hoses. The standard also mandates minimum interlayer adhesion strength for rubber hoses to prevent layer separation during use.
Testing methods
Testing procedures include hydrostatic and burst pressure tests to evaluate pressure resistance, and vacuum tests to assess structural integrity under negative pressure. Bending and flexing tests are conducted at both room and low temperatures to simulate field conditions. Aging tests involve UV exposure for plastics and ozone exposure for rubber components. Dimensional and mass measurements are performed using precision instruments like vernier calipers and steel tape measures.
FAQs
