Th
25、is European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2018, and conflicting national standards shall be withdrawn at the latest by February 2018. Attention is drawn to the possibility that some o
26、f the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1601:2014. Significant changes between this document and EN 1601:2014 include: Improved description of the carrier gases,
27、equipment and procedure for cooling the samples; Expansion of Table 1 on the oxygenate compounds data, a.o. the addition of ETBE and TAEE; Editorial changes in order to clarify the test procedure. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the followin

BS EN 1601:2017EN 1601:2017 (E) 4 Introduction This European Standard is an update of the first edition (EN 1601:1997). The scope of the test method has been updated to include petro
30、l with higher total oxygen content and with higher oxygenate contents than mentioned in the former edition. The test method is now applicable for petrol (automotive motor gasoline) with a total oxygen content up to 3,9 % (m/m), and/or with an individual oxygenate compound content higher than 15 % (m
31、/m). Such petrol is specified in EN 228 1. The previous precision data for an individual oxygenate compound content in the range of 0,17 % (V/V) to 15 % (V/V) has not been updated or extended above 15 % (V/V). A dilution procedure to measure an oxygenate compound content higher than 15 % (m/m) is in
32、cluded in the standard. Precision data have not been evaluated for this procedure. The previous precision data for oxygen content covered the range 1,5 % (m/m) to 3,0 % (m/m). The data precision for oxygen content has been updated for the range 2,1 % (m/m) to 3,9 % (m/m), based on Round Robins data
33、from 2005 to 2011 available from DIN-FAM, Germany. BS EN 1601:2017EN 1601:2017 (E) 5 1 Scope This European Standard specifies a gas chromatographic method for the quantitative determination, in unleaded petrol having a final boiling point not greater than 220 C, of individual organic oxygenate compo
34、unds in the range 0,17 % (m/m) to 15 % (m/m) in a direct analysis (without dilution), and total organically bound oxygen up to 3,9 % (m/m). For samples for which one of the oxygenate compounds content is higher than 15 % (m/m), a procedure with a dilution of the sample before the analysis is given.
35、NOTE 1 The conversion from percent mass to percent volume is done using the calculation mentioned in 8.3 and 9.5.3. NOTE 2 Precision data are not available for an oxygenate compound content higher than 15 % (m/m); see Introduction. NOTE 3 For the purposes of this European Standard, the terms “% (m/m
36、)” and “% (V/V)” are used to represent respectively the mass fraction, , respectively the volume fraction, . WARNING The use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated w
37、ith its use. It is the responsibility of users of this European Standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose. 2 Normative references The following documents,

41、ic oxygenate compounds are selectively converted to carbon monoxide, hydrogen and carbon in a pyrolytic cracking reactor. In a hydrogenation reactor, carbon monoxide is then converted to methane and subsequently detected using a flame ionization detector (FID). NOTE Guidance on the oxygen selective
42、detection (O-FID) technique is given in Annex A. BS EN 1601:2017EN 1601:2017 (E) 6 4 Reagents and materials 4.1 Gases 4.1.1 Carrier gas, helium, or nitrogen, free of hydrocarbons and oxygen and water. Hydrogen shall be dosed exactly and mixed properly to the carrier gas to ensure a stable operation
43、of the cracking reactor (see Figure A.1 and the recommendation in A.2). It is important to minimize the oxygen content of the carrier gas. To reduce the background signal it is essential to use oxygen and moisture filters. 4.1.2 Detector gases, hydrogen and air suitable for flame ionization detector
44、. WARNING Hydrogen is explosive when mixed with air at concentrations ranging approximately from 4 % (V/V) to 75 % (V/V). All joints and lines carrying hydrogen shall be made gas tight to prevent leakage of hydrogen into a confined space. 4.1.3 Cracking reactor gas, helium or nitrogen, used as purge
45、 gas to protect the platinum/rhodium element (see Figure A.1). 4.2 Reagents for the preparation of calibration samples 4.2.1 Use only reagents of recognized analytical grade. Reagents shall be not less than 99,0 % (m/m) pure. Calibration samples should be combinations of the following reagents: 4.2.
46、2 methanol (MeOH); 4.2.3 ethanol (EtOH); 4.2.4 propan-1-ol n-propyl alcohol (NPA); 4.2.5 propan-2-ol iso-propyl alcohol (IPA); 4.2.6 butan-1-ol n-butyl alcohol (NBA); 4.2.7 butan-2-ol s-butyl alcohol (SBA); 4.2.8 2-methylpropan-2-ol tert-butyl alcohol (TBA); 4.2.9 2-methylpropan-1-ol iso-butyl alcoh
47、ol (IBA); 4.2.10 2-pentanol (SAA); 4.2.11 2-methoxy-2-methylpropane Methyl tert-butyl ether (MTBE); 4.2.12 2-methoxy-2-methylbutane tert-Amyl methyl ether (TAME); 4.2.13 2-Isopropoxypropane Diisopropyl ether (DIPE); 4.2.14 2-Ethoxy-2-methyl-propane Ethyl tert-butyl ether (ETBE); 4.2.15 2-Ethoxy-2-me
48、thylbutane tert-Amyl ethyl ether (TAEE); 4.2.16 butan-2-one methyl-ethyl ketone (MEK); BS EN 1601:2017EN 1601:2017 (E) 7 4.2.17 acetone dimethyl ketone (DMK). 4.3 Internal standards Use one of the reagents listed in 4.2. If all of these reagents are likely to be present in the sample under test, use
49、 a different organic oxygenate compound of the same purity. The internal standard of choice shall elute at a different retention time as components present in the test sample. 4.4 Oxygenate free petrol Petrol examined to ensure that it contains no oxygenate compounds detectable by this test method. Cool the oxygenate free petrol to between 0 C and 5 C before the preparation of the calibration samples and test samples. 5 Apparatus 5.1 Gas chromatographic assembly 5.1.1 Gas chromatograph, equipped w
