Scope

Scope: This document specifies a method for rapid quantitative detection of automotive gasoline using a combination of near-infrared spectroscopy and chemometrics. This document is applicable to the rapid detection of octane number, vapor pressure, aromatic content, olefin content, benzene content, oxygen content, and methanol content in automotive gasoline. It is not recommended for use as an arbitration test. Main technical content: Table 1 Standard analysis items, methods, and repeatability and reproducibility indicators for automotive gasoline Test method Repeatability indicator Reproducibility indicator Research method Octane number GB/T 5487 90–1000 0.20 0.70 Motor method Octane number GB/T5038 2–92 0.20 0.70 Anti-knock index GB/T 5487, GB/T5038 6–96 0.20 0.70 Vapor pressure, kPa GB/T 8017 35–100 3.0 5.0 Aromatic content, % (by volume) GB/T 30519 1–35 0.92 0.33 Olefin content, % (by volume) GB/T 30519 1–20 0.61 1.7 Benzene content, % (by volume) SH/T 0713 0.1–1.2 0.03X + 0.01 0.13X + 0.05 Oxygen content, % (by mass) SH/T 0663 0.2–3.0 0.02(X1.26) 0.09(X1.27) Methanol content, % (by mass) SH/T 0663 0–1.0 0.09(X0.59) 0.37(X0.61) Note: X represents the average of the two results.
