DUS 1740:2017, Standard Test Method for Detailed Analysis of Petroleum Naphthas through n-Nonane by Capillary Gas Chromatography. (18 pages, in English)

This draft \ 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 150.8°C) are determined as a single group. This test method is applicable to olefin-free (<2% olefins by liquid volume) liquid hydrocarbon mixtures including virgin naphthas, reformates, and alkylates.
