7、all- und Brennstoffnormung. Amendments This standard differs from DIN EN 1601:1997-10 as follows: a) a dilution procedure has been included to measure an oxygenate content higher than 15 % (m/m). In this procedure detailed in Clause 9, the sample is diluted (1:1 or 1:2 mass/mass) with an oxygenate f

8、ree petrol before the addition of the internal standard and the analysis. Precision data have not been evaluated for this procedure; b) the previous precision data for oxygen content covered the range 1,5 % (m/m) to 3,0 % (m/m). The precision data for oxygen content has been updated for the range 2,

9、1 % (m/m) to 3,9 % (m/m), based on data from round robins carried out from 2005 to 2011, available from DIN-FAM, Germany; c) the scope of the test method has been updated to include petrol with higher total oxygen content and with higher oxygenate contents than mentioned in the former edition. The t

10、est 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/m). Such petrol is specified in EN 228. Precision data have not been evaluated for this procedure and consequent

11、ly the previous precision data for an individual oxygenate compound content within the range of 0,17 % (m/m) to higher than 15 % (m/m) have not been updated or extended above 15 % (m/m) so that automotive ethanol (E85) fuel, for example, can be included in the scope. d) the original Annex A on densi

12、ties of oxygenate compounds has been deleted and some of these compounds are now included in Table 1; e) chromatograms have been updated and the description of gas chromatographic equipment has been improved by including a schematic O-FID instrument configuration in the new Annex A.

This European Standard shall be given the status of a national standard, either by publication of an identical text

27、or by endorsement, at the latest by October 2014, and conflicting national standards shall be withdrawn at the latest by October 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsibl

28、e for identifying any or all such patent rights. This document supersedes EN 1601:1997. The major updates towards the former version are: Inclusion of a dilution procedure to measure an oxygenate compound content higher than 15 % (m/m). In this procedure detailed in Clause 9, the sample is diluted (

29、1:1 or 1:2 mass/mass) with an oxygenate free petrol, before the addition of the internal standard and the analysis. 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 co

30、ntent has been updated for the range 2,1 % (m/m) to 3,9 % (m/m), based on Round Robins data from 2005 to 2011 available from DIN-FAM, Germany; The scope of the test method has been updated to include petrol with higher total oxygen content and with higher oxygenate contents than mentioned in the for

31、mer 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/m). Such petrol is specified in EN 228 1. Precision data have not been evaluated for this proc

32、edure and consequently the previous precision data for a individual oxygenate compound content in the range of 0,17 % (m/m) higher thanto 15 % (m/m) have not been updated or extended above 15 % (m/m), in order to introduce for instance automotive ethanol (E85) fuel in the scope. Deletion of the orig

33、inal Annex A on densities of oxygenate compounds and inclusion of some of them in Table 1; Updated chromatograms and improved description of the gas chromatographic equipment with inclusion of a schematic instrument O-FID instrument configuration in the new Annex A. According to the CEN-CENELEC Inte

34、rnal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, I

DINEN 1601:2014-07EN 1601:2014 (E) 4 1 Scope This European Standard specifies a gas chromatographic method for the quant

36、itative determination, in unleaded petrol having a final boiling point not greater than 220 C, of individual organic oxygenate compounds 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

37、 the oxygenate compounds content is higher than 15 % (m/m), a procedure with a dilution of the sample before the analysis is given. NOTE 1 Precision data are not available for an oxygenate compound content higher than 15 % (m/m); see Foreword. NOTE 2 For the purposes of this European Standard, the t

38、erms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, , and the volume fraction, .

39、d with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following documents, in whole or in part, are normatively referenced

Few percentages of hydrogen (used as auxiliary gas) shall be mixed to the carrier gas (see Figure A.1). Hydrogen shall not be

45、used as a carrier gas because it will interfere with the cracking reaction. IMPORTANT It is important to minimize oxygen in 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 detec

46、tor. 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 pu
