and policies in the design and construction of fueling stations, unify technical
requirements, achieve safety and applicability, advanced technology, economical
rationality.
1.0.2 This standard is applicable to the design and construction of newly built, expanded,
reconstructed automobile oil fueling stations, gas stations, oil and gas combined fueling
stations, oil and hydrogen combined fueling stations, gas and hydrogen combined
fueling stations, oil and gas and hydrogen combined fueling stations.
1.0.3 The design and construction of vehicle oil fueling, gas fueling, hydrogen fueling
stations shall not only comply with this standard, but also comply with the relevant
current national standards.
2 Terms and abbreviations
2.1 Terms
2.1.1 Fueling station
It is a place for fueling motor vehicles with vehicle fuel, including gasoline, diesel,
LPG, CNG, LNG, hydrogen, liquid hydrogen. It is a generic term of oil fueling
station, gas fueling station, oil and gas combined fueling station, oil and hydrogen
combined fueling station, gas and hydrogen combined fueling station, oil and gas
and hydrogen combined fueling station
2.1.2 Oil fueling station
A place which has oil storage facilities AND uses fuel dispensers to refuel motor
vehicles with gasoline (including methanol gasoline, ethanol gasoline), diesel and
other vehicle fuels.
2.1.3 Gas fueling station
It is a place which has gas storage facilities AND uses a gas dispenser to refill motor
vehicles with vehicle gas, such as LPG, CNG or LNG.
transportation; CNG and hydrogen can be supplied by long-tube trailers or tube-bundle
containers or pipeline delivery.
3.0.2 The scale of automobile oil fueling, gas fueling and hydrogen fueling stations
shall be determined according to resource conditions, market demand, surrounding
environment and other factors. Oil fueling stations, gas fueling stations, hydrogen
fueling stations can be jointly built, in accordance with Article 3.0.12 ~ Article 3.0.23
of this standard.
