9、d This document (EN 14214:2008) has been prepared by Technical Committee CEN/TC 19 “Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standa
10、rd, either by publication of an identical text or by endorsement, at the latest by May 2009, and conflicting national standards shall be withdrawn at the latest by May 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/
11、or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14214:2003. This European Standard exists in parallel with EN 590. Significant technical changes between this European Standard and the previous edition are: suitable limits and test m
12、ethods on the esters, glycerides and stability characteristics of FAME resulting from EU-funded research programmes BIOSTAB and BIOScopes have been incorporated, although a possible replacement for iodine value is still under discussion in CEN/TC 19; the phosphorus limit has been lowered from 10 ppm
13、 to 4 ppm, as a first reasonable step towards meeting the needs of the latest technology engines, being a measurable amount and achievable with not too large investments by the FAME producers; allowance of the automatic Pensky-Martens test method as an alternative for flash point determination and a
14、 corresponding change of the limit from 120 C to 101 C; addition of a workmanship subclause (5.4.5); inclusion of a note referring to good house keeping via CEN/TR 15367-1; a note to clarify that cold flow requirements of fatty acid methyl esters (FAME) when used as an extender for diesel according
15、to EN 590 (as set out in Table 2) do not apply; a general update of the revised test methods, some of them already having been included in the Technical Corrigendum to the previous version. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following count
16、ries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spai
17、n, Sweden, Switzerland and the United Kingdom. EN 14214:2008 (E) 4 Introduction This European Standard gives all relevant characteristics, requirements and test methods for fatty acid methyl esters (FAME), which are known at this time to be necessary to define the product to be used as automotive di
18、esel fuel. Many of the test methods included in this European Standard were the subject of interlaboratory testing to determine their applicability and their precision in relation to different sources of FAME. These FAME were produced from vegetable oils available in the market at that time, i.e. ra
19、peseed, palm, soy and sunflower oil. Concerning total contamination, an interlaboratory study with field samples, following a study with artificial samples, is pending and therefore the repeatability and reproducibility of EN 12662 have not yet been fully established. The precision for volume percen
20、tage levels of FAME of 7, 10 and 100 will be investigated. EN 14214:2008 (E) 5 1 Scope This European Standard specifies requirements and test methods for marketed and delivered fatty acid methyl esters (hereafter known as FAME) to be used either as automotive fuel for diesel engines at 100 % concent
21、ration, or as an extender for automotive fuel for diesel engines in accordance with the requirements of EN 590. At 100 % concentration it is applicable to fuel for use in diesel engine vehicles designed or subsequently adapted to run on 100 % FAME. NOTE For the purposes of this European Standard, th
22、e terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、 Test Method for Distillation of Petroleum Products at Reduced Pressure 3 Sampling Samples shall be taken as described in EN ISO 3170 or EN ISO 3171 and/or in accordance with the requirements of national standards or regulations for the sampling of automotive diesel fuel. The national requirements s
37、hall be set out in a national annex to this European Standard, either in detail or by reference only. In view of the sensitivity of some of the test methods referred to in this European Standard, particular attention shall be paid to compliance with any guidance on sampling containers, which is incl
38、uded in the test method standard. EN 14214:2008 (E) 7 4 Pump marking Information to be marked on dispensing pumps used for delivering FAME diesel fuel, and the dimensions of the mark shall be in accordance with the requirements of national standards or regulations for the marking of pumps for automo
39、tive diesel fuel. Such requirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. 5 Requirements and test methods 5.1 Dyes and markers The use of dyes or markers is allowed. 5.2 Additives In order to improve the performance quality, th
40、e use of additives is allowed. Suitable fuel additives without known harmful side effects are recommended in the appropriate amount, to help to avoid deterioration of driveability and emissions control durability. Other technical means with equivalent effect may also be used. NOTE 1 Deposit forming
41、tendency test methods suitable for routine control purposes have not yet been identified and developed. NOTE 2 For further information on preventing contamination by water or sediment that may occur in the supply chain it is advisable to check CEN/TR 15367-1 1. 5.3 Stabilizing agents In order to imp
42、rove the long term stability of FAME, it is recommended that stabilizing agents should be added to the product immediately after its production, at least before its eventual blending into a mixture with petroleum based diesel fuel. 5.4 Generally applicable requirements and related test methods 5.4.1
43、 When tested by the methods indicated in Table 1, FAME shall be in accordance with the limits specified in Table 1. The test methods listed in Table 1 have been shown to be applicable to FAME in an interlaboratory test programme. Precision data from this programme are given in normative Annex A, whe
44、re these were found to be different from the precision data given in the test methods for petroleum products. 5.4.2 In case of a need for identification of FAME, a recommended method based on separation and characterisation of FAME by LC/GC is EN 14331 2. 5.4.3 In case of a need for a check upon FAM
45、E quality, iodine value of FAME may be calculated by the method presented in Annex B, but this method does not constitute an alternative to the iodine value requirement of Table 1. See also the Foreword and Introduction. 5.4.4 The limiting value for the carbon residue given in Table 1 is based on pr
46、oduct prior to addition of ignition improver, if used. If a value exceeding the limit is obtained on finished fuel in the market, EN ISO 13759 shall be used as an indicator of the presence of a nitrate-containing compound. If an ignition improver is thus proved present, the limit value for the carbo
47、n residue of the product under test cannot be applied. The use of additives does not exempt the manufacturer from meeting the requirement of maximum 0,30 % (m/m) of carbon residue prior to addition of additives. 5.4.5 FAME fuel shall be free from any adulterant or contaminant that may render the fue
48、l unacceptable for use in diesel engine vehicles.
