2 7.5 Deletion Deleted the max residual pressure limit a 100 psi for foam maker
3 7.5 Deletion Deleted the design method option (5 Ls (80 gpm) per chamber at 520 kPa gauge (75 psig) which was tailored fora specific product in the past. The design method will be based on the application rate ( The capacity of the foam system shall be based on 0.34 L/s/m² (0.5 gpm/ft²) of foam solution per area between the foam dam and tank shell )
4 7.11 Deletion Separating the time for tank hydrotest from foam system performance test, and deleting the minimum floating roof level requirement during foam system acceptance test “no lower than 25% of its maximum
