Alcance y aplicabilidad

This standard specifies the requirements, marking, performance inspection, and use appraisal of portable tanks for dangerous goods. It is specifically applicable to the inspection of portable tanks used for the transport of Class 3 to Class 9 dangerous goods. It is mandatory for manufacturers and users of portable tanks transporting these hazardous materials in China. The standard aligns its technical content with the UN Recommendations on the Transport of Dangerous Goods (15th revised edition).

Requisitos técnicos

The standard outlines comprehensive technical requirements across several mandatory chapters. Chapter 5 specifies detailed marking requirements, mandating permanent metal nameplates with essential data like test pressure and maximum allowable working pressure. Chapter 6 covers general requirements, including protection against transport impacts, loading degree limits, and specific provisions for transporting Class 3, 5.2, 4.1, 7, and 8 substances. Manufacturers must ensure that materials and designs prevent dangerous reactions and withstand dynamic and thermal loads. Chapter 8 details use appraisal criteria, requiring that tanks be compatible with the hazardous contents and equipped with appropriate pressure relief devices, such as spring-loaded valves, frangible discs, or fusible plugs, designed according to ISO 4126-1.

Métodos de ensayo

The standard mandates several performance tests to verify the integrity of portable tanks. These include the impact test, which evaluates the tank's ability to withstand typical mechanical shocks during rail transport; the pressure test, checking for leaks under specified constant pressure; the leakproofness test, using water to inspect the shell and equipment; and the hydraulic test, ensuring no deformation or leakage under hydraulic pressure. These tests must be conducted before first use and periodically at 2.5 and 5-year intervals.
