To find out the current liquefied petroleum gas quality safety in Sichuan province and provide foundation for strengthening quality safety supervision and administration, 100 liquefied petroleum gas samples were selected and tested by China National Quality Supervision﹠Inspection Center For Petroleum and Natural Gas. Testing result showed that the pass rate of liquefied petroleum gas was only 68%. The main reason for the failure is that most of the liquefied petroleum gas is adulterate with dimethyl ether. It can be concluded that the liquefied petroleum gas product quality is not optimistic in Sichuan province.
