適用範囲

GB 1787-2018 applies to aviation piston engine fuels produced from approved raw materials and blended with appropriate additives. It covers the classification, marking, technical requirements, testing methods, and delivery specifications for these fuels. This standard is mandatory for all manufacturers and suppliers of aviation gasoline in China. It specifically categorizes fuels into five grades: 75, UL91, 95, 100, and 100LL, where UL stands for unleaded and LL stands for low lead.

技術要求

The standard mandates strict physical and chemical properties for aviation fuels to ensure engine performance and safety. Chapters 4 and 5 contain the mandatory technical and inspection requirements. Key parameters regulated include motor method octane number, lead content, and net heat of combustion, which are critical for engine anti-knock characteristics and energy output. Additionally, the standard specifies limits for distillation characteristics, vapor pressure, and freezing point to ensure proper fuel vaporization, cold-start performance, and high-altitude operational safety. Strict thresholds are also set for sulfur content, oxidation stability, and copper strip corrosion to prevent engine component degradation and fuel system fouling. Furthermore, the standard outlines specific requirements for fuel coloration and dye content (e.g., blue, yellow, orange dyes) to visually distinguish between different fuel grades. It also permits the use of specific antioxidants and anti-static additives, provided they meet the referenced regulatory criteria.

試験方法

The standard outlines a comprehensive suite of testing procedures to verify compliance. Key evaluations include the motor method octane number test (per GB/T 503) and supercharge method rating (per SH/T 0506). For elemental and compositional analysis, it mandates specific methods such as X-ray spectroscopy for lead content and ultraviolet fluorescence for sulfur content. Other critical tests cover distillation characteristics, vapor pressure measurement, freezing point determination, and copper strip corrosion testing, with clearly defined arbitration methods in case of disputed results.

よくある質問

What products are regulated under GB 1787-2018?

The standard regulates aviation piston engine fuels, categorized into five grades based on motor method octane number: Grade 75, UL91 (unleaded), 95, 100, and 100LL (low lead).

Are there any updates from the previous version of GB 1787-2018?

The 2018 version introduced the UL91 and 100LL grades, added new testing methods for lead content, color, density, and vapor pressure, and removed iodine value and existent gum parameters. It also restricted acidity and aromatic requirements to grades 75 and 95.

Does GB 1787-2018 reference international standards?

Yes, the standard incorporates several international methodologies, such as ASTM D5059 for lead determination and ASTM D2392 for color measurement, aligning certain testing protocols with global practices while maintaining specific domestic arbitration methods.
