b)            for outdoor installation or indoor installation;

c)            certified as a system for the direct fueling of vehicles

d)            for ambient temperatures not below minus 40° C (minus 40 °F);

e)            for nominal voltage not exceeding 600 Volts AC;

f)             for fill pressure not exceeding specified vehicle service pressure;

g)            for maximum inlet flow rate not exceeding 10 SCFM (17 SCMH);

h)            intended for connection to either a utility gas piping system in accordance with requirements of the applicable Code or a mobile gas supply source;
