12、 type is known,but the contaminant fuelis not available for calibration,an estimate of the contaminantfuel concentration can be calculated using average responsefactors.If the nature of the contaminant fuel is unknown,acontaminant concentration cannot be calculated,and the testmethod can only be use
13、d only to indicate the presence orabsence of fuel contamination.5.2 Fuels containing aromatic compounds,such as dieselfuel and gasoline,as well as other aromatic-containing hydro-carbon materials,such as crude oil,coal oil,and motor oil,canbe determined by this test method.The quantitation limit for
14、diesel fuel is about 75 mg/kg.Approximate quantitation limitsfor other aromatic-containing hydrocarbon materials that canbe determined by this screening test method are given in Table1This test method is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility
