Introduction

Standard Overview and Technical Evolution

This standard modification adopts the ASTM D5622-17 method. The main technical improvements include:

Improvement Dimensions	ASTM D5622-17	NB/SH/T 0986-2019
Scope of Application	Gasoline/Methanol Fuel Only	Add Diesel Testing
Reference Standards	American Standard System	Chinese National Standard/Industry Standard
Technical Details	Basic Methods	Additional instrument requirements/Q control

Core detection principle

A high temperature cracking tube (950-1300℃) is used to convert the sample oxygen element into CO/CO₂, and the oxygen mass fraction is inferred by detecting the gas content. Critical control points:

Carrier gas purity ≥99.995%
Precise control of sample volume (1-10μL/mg)
Tin boat packaging to prevent air interference

Comparison of method differences

Gasoline detection case: Use methyl tert-butyl ether standard for calibration, which requires matching quartz reaction tube and infrared detector, and the relative deviation must be ≤2%

Special treatment for diesel detection: Methyl oleate calibration is required, and the precision is not specified

Implementation points

Soluble water must be removed during sample pretreatment (see Appendix A)
Recalibration is required every 10 samples
Quality control sample recovery rate ≥ 85%
Result report is accurate to 0.01%

Industry application value

This standard provides key technical support for biodiesel blending and ethanol gasoline quality monitoring, and helps to achieve:

Combustion efficiency optimization
Tail emission control
New energy fuel development
