The standard addresses systems operating at specific nominal pressures. Previous versions, such as ISO 14520-5:2016 , covered systems at 25 bar, 34.5 bar, 42 bar, and 50 bar, typically using nitrogen as the propellent. The latest 2024 version incorporates updated, higher-pressure options to enhance flexibility. C. Concentration and Design Quantities
