ASTM D7756-11<\/h3>\n

Historical Standard: Standard Test Method for Residues in Liquefied Petroleum (LP) Gases by Gas Chromatography with Liquid, On-Column Injection<\/h4>\n
\n

ASTM D7756<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination, by gas chromatography, of soluble hydrocarbon materials, sometimes called \u201c<\/span>oily residue,\u201d<\/span> which can be present in Liquefied Petroleum (LP) Gases and which are substantially less volatile than the LPG product.<\/p>\n

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\u00b0<\/span>C and 522\u00b0<\/span>C (C10<\/sub> to C40<\/sub>) in LPG. Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected.<\/p>\n

1.3 Units<\/span>\u2014<\/span>The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
