SUPERSEDED (see Active link, below)
ASTM D2425
1. Scope
1.1 This test method covers an analytical scheme using the mass spectrometer to determine the hydrocarbon types present in virgin middle distillates 204 to 343C (400 to 650F) boiling range, 5 to 95 volume % as determined by Test Method D 86. Samples with average carbon number value of paraffins between C 12 and C 16 and containing paraffins from C 10 and C 18 can be analyzed. Eleven hydrocarbon types are determined. These include: paraffins, noncondensed cycloparaffins, condensed dicycloparaffins, condensed tricycloparaffins, alkylbenzenes, indans or tetralins, or both, C n H 2 n -10 (indenes, etc.), naphthalenes, C n H 2 n -14 (acenaphthenes, etc.), C n H 2 n -16 (acenaphthylenes, etc.), and tricyclic aromatics. Note 1This test method was developed on consolidated Electro-dynamics Corp. Type 103 Mass Spectrometers.
