6.3 A spout opening in the body or top of a safety can shall be above the rated liquid level as marked in 24.4.
6.4 A safety can having a nominal capacity of 1.1 US quarts (0.94 L) or less shall not have more than one opening. The opening shall be adapted for pouring and filling.
6.5 A safety can shall not have more than two openings. 6.6 The separate pouring and filling spring-loaded lids or valves on a Type II safety can shall operate independently of each other.
6.7 A pouring spout shall be constructed to reduce the likelihood of spillage during pouring.
6.8 A Type II safety can shall incorporate a vent valve to permit the free discharge of liquid during a pouring operation. The vent valve shall open and close automatically and simultaneously with the opening and closing of the pouring valve. 6.9 A Type II safety can shall be affixed with a conductive nozzle for bonding between containers when dispensing.
6.10 Internal pressure ranging between 3 to 5 psig (20.7 to 34.5 kPa) shall be relieved by overcoming the spring pressure on the spring-closing, pouring- or filling- lid or valve or through an independent pressure-relief device.
6.11 The bottom surface of a safety can shall be recessed at least 1/8 in (3.2 mm) above the bottom perimeter of the sidewall to reduce the likelihood of puncturing or abrading the bottom.
6.12 The bottom edge of a metal safety can having a nominal capacity of 3 US gal (11.4 L) or more shall be reinforced or shall be provided with a metal support ring.
7 Pouring Spouts and Fill Fittings
7.1 A metallic pouring spout or fill fitting shall be of corrosion-resistant metal or of ferrous metal that is provided with a corrosion-resistant coating that complies with the requirements in Corrosion-Resistant Coatings, Section 13.
7.2 The wall of a cast pouring spout or fill fitting shall not be less than 1/8 in (3.2 mm) thick. The wall thickness of tubing or other drawn material shall not be less than 0.05 in (1.3 mm).
7.3 The internal diameter of a spout or fill fitting shall not be less than the appropriate value specified in Table 7.1.
8 Pouring Nozzles – Type II Safety Cans
8.1 The metal used in a flexible nozzle shall not be less than 0.010 in (0.25 mm) thick. A rigid nozzle shall not be less than 0.035 in (0.89 mm) thick.
8.2 The discharge end of a flexible nozzle shall include an FMD or a flame arrester that has successfully passed Section 18, Flame Mitigation Device Effectiveness. 8.3 The valve or inlet end of a flexible nozzle shall be supported or reinforced by a closely wound external helical spring. The spring shall not be less than 3 in (76.2 mm) long and shall be secured in place.
8.4 A nozzle shall be attached to the pouring spout by a method that provides a leak-free connection and is conductive to the safety can body.
8.5 A nozzle intended for use in automotive fueling applications for pouring directly into the fuel tank of a vehicle requiring unleaded gasoline shall have a maximum outside diameter of 0.86 in (21.8 mm). When a safety can is equipped with a nozzle having an outside diameter not greater than 0.86 in (21.8 mm), the safety can may be marked in accordance with 24.3.
