What standard can the leak-proof performance of a self-bunded fuel tank meet

2025-07-10 Leave a message

Self-Bunded Fuel Tank Performance Standards

International Standards (ISO)

  • ISO 22241 series governs fuel storage system requirements
  • Mandates secondary containment holding ≥110% of inner tank capacity
  • Focuses on leak-proof performance and environmental protection
  • Key Requirement

    Outer bund must provide robust barrier against leaks from primary tank

    European Standards

  • EN 12285-1 regulates static fuel storage tank design
  • Requires rigorous pressure and vacuum tests to verify seal integrity
  • ATEX directives apply for hazardous locations
  • Compliance Testing

    Must demonstrate zero measurable leakage under specified conditions

    North American Standards

  • UL 142 for double-walled tanks:
    • Hydrostatic testing at 3 psi for 30 minutes
    • No detectable leakage permitted
  • EPA SPCC rule requires secondary containment for 100% capacity
  • Industry-Specific Requirements

  • Additional criteria for specialized applications:
    • Enhanced corrosion resistance
    • Impact and temperature fluctuation tolerance
    • Marine environment durability
  • Third-party certification often required for validation
  • Manufacturer Compliance

    Must meet both regulatory requirements and operational safety needs
