Provides for two classes of can of capacity up to 0.085 cubed on the basis of resistance to impact at low temperatures, viz. cans tested for impact resistances at -14 to -10°C, and cans tested at -2 to 0°C. The cans are also tested at ambient. Also specified are material requirements and certain design parameters, and the composition clause includes requirements for ensuring adequate protection against degradation by ultraviolet light.
