Foreword
Chapter 4 of this standard (except for test methods) is mandatory AND the rest is recommended.
This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB 19159-2003; as compared with GB 19159-2003, the main technical changes are as follows.
- DEFINE the scope of application as “liquefied petroleum gas for ignition type of internal combustion engine” (SEE Chapter 1);
- DELETE the limitation of the component mass fraction (SEE Table 1;
Chapter 4 of 2003 version);
- DELETE the limitation on grease observation (SEE Table 1; Chapter 4 of 2003 version);
- MODIFY the total sulfur content from “< 270 mg/m3” to “not more than 50 mg/kg” (SEE Table 1; Chapter 4 of 2003 version);
- MODIFY the evaporation residue from “not more than 0.05 mL/100 mL” to “not more than 60 mg/kg” (SEE Table 1; Chapter 4 of 2003 version);
- MODIFY the density measurement temperature from “20 °C” to “15 °C”
(SEE Table 1; Chapter 4 of 2003 version);
- MODIFY the vapor pressure measurement temperature from “37.8 °C” to
“40 °C” (SEE Table 1; Chapter 4 of 2003 version);
- ADD the technical requirements for motor octane number (SEE Table 1); - Based on the temperature at the minimum vapor pressure 150 kPa, DIVIDE the product level (SEE Table 1);
- ADD the calculation method of liquefied petroleum gas motor octane
number, measurement method and calculation method of the absolute
vapor pressure and gauge pressure of liquefied petroleum gas, the vapor pressure limit of liquefied petroleum gas of different designations
corresponding to 40 °C, AND the detection method of the odor of liquefied petroleum gas (SEE Appendix).
This standard, combining with Chinese vehicle liquefied petroleum gas
resources, vehicle use characteristics and status quo, through modification, adopts the EU standard EN 589.2008 “Automotive fuels - LPG - Requirements Automotive liquefied petroleum gases

3 Classification and marking
3.1 Product Classification
a) When the new product is put into production OR the product is subjected to finalization assessment;
b) When the raw materials, processing technology, and so on have
significant changes AND the production is started after overhauling;
c) When there is significant difference between the exit-factory inspection results and the last type inspection results.

Calculation method of motor octane number of liquefied petroleum gas
A.1 Overview
This appendix describes the method of calculating the motor octane number by analyzing the hydrocarbon composition of liquefied petroleum gas (LPG). A.2 Principles
The hydrocarbon composition of the liquefied petroleum gas sample is
measured by gas chromatography method, AND the motor octane number of
the liquefied petroleum gas sample is calculated from the motor octane number of each component.
A.3 Determination
The concentration of each component is determined using SH/T 0614 (a
component having a molar concentration of more than 0.1% in the gas sample is detected).
