Compliance overview
Scope and applicability
This standard applies to No. 3 jet fuel used in aviation turbine engines. It covers fuels processed from natural crude oil or its fractions, as well as fuels blended with synthetic hydrocarbon kerosene components such as FT-SPK and HEFA-SPK. This standard is mandatory for all manufacturers and suppliers of aviation turbine fuel entering the Chinese market.
Technical requirements
GB 6537-2018 establishes mandatory technical specifications for aviation turbine fuel. The requirements are categorized into composition, volatility, fluidity, combustion, corrosion, stability, and cleanliness. For composition, the standard sets strict limits on total acid value, aromatic and olefin content, and total sulfur mass fraction. Regarding volatility and fluidity, the standard defines parameters for distillation characteristics, flash point, density at 20°C, and freezing point. These parameters ensure the fuel's safe and reliable performance under extreme operational temperatures. The standard also mandates specific combustion and stability metrics, including minimum net heat value and smoke point, alongside thermal oxidation stability limits. Furthermore, it outlines cleanliness requirements such as water separation index and solid particle contaminant levels. Additionally, the standard includes normative appendices for synthetic blending components. It specifies that the volume fraction of FT-SPK or HEFA-SPK in the final blend shall not exceed 50%, with a minimum aromatic content of 8.0% required. Approved additives, such as anti-static and anti-oxidant agents, must strictly adhere to the prescribed dosage limits.
Testing methods
The standard references a comprehensive suite of Chinese national (GB/T) and industry (SH/T) testing standards, alongside some international methods like ASTM D3338. Key evaluations include distillation characteristic testing, flash point determination via the Abel closed cup method, and freezing point analysis. Manufacturers must ensure all testing is conducted strictly according to the designated methods listed in the standard's reference table. Alternative methods are permitted only under specific conditions, with primary methods taking precedence in case of disputes.
FAQs
What products are regulated under GB 6537-2018?
It applies to No. 3 jet fuel used in aviation turbine engines, including fuels processed from natural crude oil and those blended with synthetic hydrocarbon components like FT-SPK and HEFA-SPK.
Are there any significant updates from the previous GB 6537-2006 version?
The 2018 version transitioned to a fully mandatory standard. It introduced requirements for synthetic hydrocarbon blends, updated testing methods for total sulfur and flash point, and adjusted the upper conductivity limit to 600 pS/m. Manufacturers previously compliant with the 2006 version must update their compliance documentation.
How does GB 6537-2018 align with international standards like ASTM?
The standard incorporates methodologies analogous to international norms, such as ASTM D3338 for net heat of combustion estimation and ASTM D7359 for halogen determination. However, manufacturers must strictly adhere to the designated GB/T and SH/T testing methods for official compliance verification in China.
