ISO 8217:2024 defines the general requirements and specifications for marine fuels supplied before onboard handling, including storage, settling, centrifuging, filtration, heating, and use. This seventh edition covers distillate, bio-distillate, residual, bio-residual, FAME, synthetic, renewable, recycled-source, and blended fuels. It addresses fuel categories, sampling, general requirements, test methods, characterization, ignition quality, sulfur content, cold-flow properties, stability, sediment, contaminants, and other key fuel characteristics. The standard also includes requirements for stationary diesel engines of the same or similar type as marine engines, along with informative annexes on bio-based fuels, fuel composition, ignition characteristics, hydrogen sulfide, acid number, cold-flow behavior, ash, residual-fuel stability, unrefined used lubricating oil, specific energy, and fuel characterization.
Application Scope: Marine fuel suppliers, ship owners, ship operators, fuel testing laboratories, classification societies, engine designers, fuel treatment equipment manufacturers, and organizations responsible for specifying, purchasing, testing, storing, or using fuels in marine diesel engines and boilers.
