1.1 This test method covers the quantitative determination of a variety of chemical species in marine fuel oil (bunker fuel oil) by gas chromatography - mass spectrometry. By using the same conditions and by selecting required mass spectral selected ions, the test method may be used for the determination of other species than those for which precision statements and limits of detection have been established.

1.2 An example list of chemical species for which a limit of quantification has been determined by means of this test method is given in Table 1.

TABLE 1 Component Table

	Limit of Quantitation mg/kg
n-butyl alcohol	10
Cyclohexanol	10
n-butyl ether	10
n-butyl acylate	10
Styrene	10
alpha-pinene	10
Phenol	20
alpha-methyl styrene	10
beta-pinene	10
4-methyl styrene	10
trans-B-methyl styrene	10
3-methyl styrene	10
2-methyl styrene	10
Dicyclopentadiene	10
Limonene	10
Indene	20
1-phenyl ethanol	20
para, alpha-Dimethyl styrene	20
2,5 dimethyl styrene	20
2,4 dimethyl styrene	20
2-phenyl ethanol (phenylethanol)	20
2-Ethyl Phenol	50
2,4 Dimethyl Phenol	20
4-Ethyl Phenol (co elutes with 3-ethylphenol)	20
2-Phenoxy-1-propanol	50
2-Phenoxy ethanol	50
4-isopropylphenol	50
1-Phenoxy-2-Propanol	20
Styrene Glycol	50

1.3 Other refinery hydrocarbon fractions and their mixtures may be tested using the same test method conditions. However, the precision of this test method reflects the compounds in Table 1.

1.4 Results are reported to the nearest 1.0 mg/kg.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
