4.1 A knowledge of the hydrocarbon components comprising a petroleum naphtha, reformate, or alkylate is useful in valuation of crude oils, in alkylation and reforming process control, in product quality assessment, and for regulatory purposes. Detailed hydrocarbon composition is also used as input in the mathematical modeling of refinery processes. 4.2 Separation of naphtha components by the procedure described in this test method can result in some peaks that represent coeluting compounds. This test method cannot attribute relative concentrations to the coelutants. In the absence of supporting information, use of the results of this test method for purposes which require such attribution is not recommended. 1.1 This 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 150.88201;°C) 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. 1.2 This test method is applicable to olefin-free (<28201;% 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 988201;% point of 2508201;°C or less as determined by Test Method D3710 or D7096 or equivalent. 1.3 Components that are present at the 0.058201;% by mass level or greater can be determined. 1.4 This 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. 1.5 Detailed hydrocarbon components in olefin containing samples may ......

1.1 This specification covers styrene monomer. 1.2 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29. 1.3 The values stated in SI units are to be regarded as standard. 1.4 Consult current OSHA regulations, supplier’s Material Safety Data Sheets, and local regulations for all materials used in this specification.
