적용범위 | 1.1 This test method covers the determination, by gas chromatography, of soluble hydrocarbon materials, sometimes called “oily residue,” which can be present in Liquefied Petroleum (LP) Gases and which are substantially less volatile than the LPG product. 1.2 This test method quantifies, in the range of 10 to 600 mg/kg (ppm mass), the residue with a boiling point between 174°C and 522°C (C10 to C40) in LPG. Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected. 1.3 Appendix X3 and Appendix X4 describe additional applications which could be performed based on the hardware and procedures described in this test method. Appendix X3 describes a test procedure for expanding the analysis range to benzene, and Appendix X4 describes a test procedure for the analysis of diisopropanolamine in LPG. |
