ASTM D6615-22

Overview

ASTM D6615-22: Standard Specification for Jet B Wide-Cut Aviation Turbine Fuel is a comprehensive international standard published by ASTM. It sets forth requirements for Jet B wide-cut aviation turbine fuel, focusing on its composition, properties, performance characteristics, and approved additives. Jet B fuel is intended specifically for civil aviation and is recognized for its suitability in very low temperature environments, making it especially valuable for operations in cold climates where kerosene-type fuels may be less effective. This specification supports agencies and organizations in purchasing and supplying high-quality aviation turbine fuel under contractual agreements.

Key Topics

• Fuel Composition and Properties

  • Jet B fuel must be a blend of refined hydrocarbons derived from crude petroleum, natural gasoline, or blended with synthetic hydrocarbons.
  • The fuel is characterized by a relatively wide boiling range and higher volatility compared to kerosene-based jet fuels.

• Performance Requirements

  • Critical parameters include: aromatics, sulfur content, distillation temperature and residue, density, vapor pressure, freezing point, net heat of combustion, smoke point, naphthalene content, copper strip corrosion, thermal stability, existent gum, electrical conductivity, and water separation characteristics.

• Additive Use

  • Allows the use of antioxidants, metal deactivators, electrical conductivity improvers, leak detection additives, biocidal additives, and fuel system icing inhibitors such as diethylene glycol monomethyl ether (DIEGME). Additives must be approved for the specific aircraft and agreed upon between supplier and purchaser.

• Testing and Quality Control

  • Specifies standard ASTM test methods for each required property to ensure conformance and compatibility in aircraft, including tests for density (D1298, D4052), distillation (D86), vapor pressure (D323, D5191), freezing point (D2386, D5972), and more.

• Fuel Cleanliness and Handling

  • Requirements for visual appearance (free from water, sediment, and suspended matter) and odor.
  • Proper sampling procedures (ASTM D4057) are essential for ensuring fuel quality at the point of delivery.

Applications

• Civil Aviation: Used in aircraft certified for Jet B wide-cut fuel, especially for routes and operations encountering extremely low ambient temperatures.
• Purchasing and Contracting: Assists government and private agencies in specifying and procuring aviation turbine fuel that meets internationally recognized standards, ensuring performance and safety.
• Cold-Weather Operations: Due to its physical properties, Jet B is particularly advantageous for operations in arctic or subarctic regions.
• Fuel Handling and Maintenance: Provides clear guidelines for acceptable additives and handling practices, promoting fuel stability, storage safety, and operational reliability.
