DANSK DS/CEN ISO/TS 16558-2 PDF

This part of ISO xxxxx specifies a method for the quantitative determination of the total extractable semivolatile, the semi-volatile aliphatic and aromatic fractions of petroleum hydrocarbon content in field moist soil samples by gas chromatography. The results of the test carried out can be used for risk assessment studies related to contaminations with petroleum hydrocarbons. The method is applicable to petroleum hydrocarbon contents between XXXX mg/kg and XXXX mg/kg soil expressed as dry matter for the whole aliphatic fraction C10 to C40 as well as the aromatic fraction C10 to C40. For sub-fractions lower limits of determination can be reached. With this method all hydrocarbons with a boiling range of 174 °C to 525 °C, n-alkanes between C10H22 to C40H82, isoalkanes, cycloalkanes, alkyl benzenes, and alkyl naphthalenes and polycyclic aromatic compounds are determined as total extractable semi-volatile petroleum hydrocarbons C10 to C40; besides that semi-volatile aliphatic and aromatic fractions are specified.
