This section applies to tankers installed at gas stations, with a flow rate of no more than.200L/min for vehicles, boats, light aircraft or for moving
The dynamic tank container is filled with liquid fuel and used to store or store liquid fuel in an environment of -20 ° C ~ 40 ° C.
Note 1. The tanker installed in skid-mounted gas stations, moving vehicles, etc. should be evaluated for the suitability of the tanker.
Note 2. If the flow range exceeds.200L/min, it shall be negotiated between the manufacturer and the inspection agency according to the relevant standards.
Note 3. When the ambient temperature range of -20 ° C ~ 40 ° C is exceeded, other measures are required and negotiated between the manufacturer and the user and the inspection agency.
This section deals with the main aspects of the tanker when it is used under normal working conditions and when the manufacturer can foresee it.
