Full Description

1.1This detailed hydrocarbon analysis (DHA) test method covers the determination of hydrocarbon components paraffins, naphthenes, and monoaromatics (PNA) of petroleum naphthas as enumerated in Table 1. Components eluting after n-nonane (bp 150.8C) are determined as a single group.

(A)Extrapolated from n-C6 and n-C7. See A1.1.3.(B)Extrapolated from n-C8 and n-C9. See A1.2.3.(C)Stereoisomers.

1.2This test method is applicable to olefin-free (2% olefins by liquid volume) liquid hydrocarbon mixtures including virgin naphthas, reformates, and alkylates. Olefin content can be determined by Test Method D1319 or D6839. The hydrocarbon mixture must have a 98% point of 250C or less as determined by Test Method D3710 or D7096 or equivalent.

1.3Components that are present at the 0.05% by mass level or greater can be determined.

1.4This test method may not be completely accurate for PNA above carbon number C7; Test Method D5443 or D6839 may be used to verify or complement the results of this test method for carbon numbers C7.

1.5Detailed hydrocarbon components in olefin containing samples may be determined by DHA Test Methods D6729, D6730, or D6733.

1.6The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are given in Section 7.

1.8This 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.
