ASTM D5442-17-Reapproved2021<\/h3>\n

Active Standard: Standard Test Method for Analysis of Petroleum Waxes by Gas Chromatography<\/h4>\n
\n

ASTM D5442<\/h4>\n

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

\n

1.1<\/span> This test method covers the quantitative determination of the carbon number distribution of petroleum waxes in the range from n<\/span>-C17<\/span><\/sub> through n<\/span>-C44<\/span><\/sub> by gas chromatography using internal standardization. In addition, the content of normal and non-normal hydrocarbons for each carbon number is also determined. Material with a carbon number above n<\/span>-C44<\/span><\/sub> is determined by its difference from 100\u2009% by mass and reported as C45+<\/span><\/sub>.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> This test method is applicable to petroleum derived waxes, including blends of waxes. This test method is not applicable to oxygenated waxes, such as synthetic polyethylene glycols (for example, Carbowax2<\/span><\/span>), or natural products such as beeswax or carnauba.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> This test method is not directly applicable to waxes with oil content greater than 10\u2009% as determined by Test Method D721<\/span>.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> 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 consult and establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n

\n

1.6<\/span> This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.<\/i><\/p>\n<\/p><\/div>\n
