secretariat of which is held by NEN This 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of an identical text or by endorsement, at the latest by July 2014, and conflicting national standards shall be withdrawn at the latest by July 2014 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights

The start and finish of text introduced or altered by amendment is indicated in the text by tags This document has originally been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s) Deleted text Significant technical changes between this European Standard and the previous edition are: — extension towards distillate heating fuels The former specification for FAME for heating fuel applications (EN 14213) also needed to be aligned, but effectively only one quality was supplied and required by heating fuel suppliers in the European market; — further clarification regarding the use of dyes and markers due to its new heating fuel application; — an update of the specification in the perspective of blending at up to 10 % (V/V) of FAME in automotive diesel fuel; — removal of identification of parallel existence with EN 590 as FAME is being used for more than one blending purpose; — discrimination between climate requirements for use for 100 % as fuel for diesel engines and for use as blend component in diesel fuel This is done by introducing a new Table for seasonal grades to be set nationally It thus requires countries to present two sets of seasonal choices in a national annex to this standard; — introduction of additional requirements for FAME for use as a blending component as a first, intermediate, step towards solving precipitation problems observed in the market during cold periods Further work towards limitation of impurities, more specifically steryl-glycosides, and BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) regarding monoglyceride determination is on-going A performance test, such as a filterability test, is anticipated to solve this issue in the longer term; — a decrease of the monoglycerides content limit from 0,8 % (m/m) to 0,7 % (m/m); — deletion of the requirement on carbon residue as it is no longer considered necessary; — an increase of the oxidation stability requirement from h minimum to h minimum; — introduction of additionally developed test methods for iodine value, phosphorus content CFPP and sulfur content, EN 16300, EN 16294, EN 16329 and EN ISO 13032, respectively. Plus updating towards revised sulfur and sulfated ash content determination test methods; — updating of test methods on esters, (mono) glycerides, polyunsaturated fatty acids oxidation stability, total contamination, and stability characteristics of FAME, resulting from work under CEN/TC 19 and in cooperation with CEN/TC 307, either as final publication or as technically assessed and accepted draft texts The test method procedure for total contamination (EN 12662) has been technically updated to specifically allow improved applicability to FAME (see CEN/TC 19/N 1512R, report I); — combination of all sub-clauses dealing with additives in one and aligning them with similar requirements in EN 590 — a re-evaluation of Table A.1 has been executed and it was agreed to complete Annex A by presenting reproducibility information for all test methods that is mainly of interest to people handling the product. According to the CEN/CENELEC Internal Regulations, the national standards organisations 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, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) 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 diesel fuel and in heating applications Many of the test methods included in this European Standard have been the subject of several interlaboratory testing to determine their applicability and their precision in relation to different sources of FAME These FAMEs were produced from vegetable oils available in the market at the time, mainly rapeseed, palm, soy and sunflower oil This does not imply any restrictions towards the feedstock for the fats and oils from which the FAME is made to comply with this European Standard (see Foreword) 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 FAME is investigated Concerning cold temperature properties of diesel blends related to the quality of the FAME used as a blending component, strong indications towards the relationship with saturated mono-glycerides and steryl-glycosides have become known As no test method to detect those components separately has yet been developed, an interim solution in setting CFPP and cloud point limitations has been included in this standard (see Table 3) A study within CEN has indicated that FAME conforms to the current precision statements of EN 116 and EN 23015 Although there are technical indications that iodine value can be removed as an indication for FAME stability, relaxation at this time would be premature Until the stability safeguards introduced by this revision have been proven in the market, it is maintained, also preventing unnecessarily high usage of anti-oxidant additives In order to meet the needs of the latest technology engines, lowering of the phosphorus limit and the limit of sodium and potassium is under investigation BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) 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 fuel for diesel engines and for heating applications at 100 % concentration, or as an extender for distillate fuel for diesel engines in accordance with the requirements of EN 590 and for heating fuel At 100 % concentration it is applicable to fuel for use in diesel engines and in heating applications designed or subsequently adapted to run on 100 % FAME NOTE For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ

a range of temperatures from 20 °C to 60 °C, to density at 15 °C is based on data published at the International Conference on Standardization and Analysis of Biodiesel, Vienna, November 1995 [6] NOTE At the moment a DIN investigation is generating additional data The density of seven samples of FAME was measured by pyknometer at temperatures over the range 20 °C to 60 °C The mean correction factor over the range was calculated as 0,723 kg/(m °C), with a standard deviation of 1,2 % The average density of the FAME samples at 15 °C was calculated as 886,5 kg/m The following formula shall be used for the calculation of density of FAME at 15 °C (ρ(15), given in kg/m ), using the density (ρ(T)) at a certain temperature (T), determined by EN ISO 3675 over the range of temperatures from 20 °C to 60 °C: ρ(15) = ρ(T) + 0,723(T – 15) (B.1) 17 BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) Annex C (informative) Background information for national climate grades selection C.1 General For FAME that is to be used for blending EN 590 diesel fuel it is essential that appropriate climate grades are selected from Table 3a and Table 3b by National Standardization Bodies to take account of seasonal temperature variations to avoid cold flow problems in the market NOTE The climate grades refer to FAME that has not been treated with cold flow additive Table 3a requires the national choice of appropriate values of cloud point and CFPP to match the prevailing climate Table 3b is used to select suitable monoglyceride contents in order to minimise the risk of cold flow problems In addition, market experience has indicated that when FAME is subjected to longer periods of low temperature, filter plugging can occur if additional factors, one of which being saturated monoglyceride contents, are not controlled However, at present there is no suitable test method for the determination of saturated monoglyceride content in FAME A correlation model has been developed to estimate approximate content of saturated monoglycerides based upon cloud point (EN 23015), total saturated fatty acids (derived from EN 14103) and total monoglyceride content (EN 14105) The content of saturated fatty acid esters is calculated from intermediate results of EN 14103 From the estimated content of saturated monoglycerides in the FAME, the content of saturated monoglycerides in the final diesel fuel blend can be calculated using the FAME density (EN ISO 12185) and FAME content in diesel using EN 14078 The model is based on the assumption that saturated fatty esters, saturated fatty acids and saturated monoglycerides are present in the same proportions This correlation, however, is subject to some uncertainty due to the precision of the input parameters described above It is not possible to precisely estimate the uncertainty as there is no reproducibility data available for the saturated fatty acid methyl esters derived from EN 14103 The uncertainty has been estimated using the guidance set out in EN ISO 4259 and can vary from about −50 % to +50 % of the estimated content of the saturated monoglycerides A report presenting further background to the correlation model and the precision is under development in CEN CAUTION — It is recommended that National Standardization Bodies take this uncertainty into account when selecting the seasonal climate grades from Tables 3a and 3b Because of this high level of uncertainty the correlation described in this annex cannot be used to precisely specify saturated monoglyceride contents in the FAME and hence the finished EN 590 diesel fuel It does however provide a useful tool to understand the differences between the various climate grades with respect to their potential cold flow performance See also 5.4.3.1 Climate grades are chosen to reflect possible market blending volumes of FAME at % (V/V) to control finished EN 590 monoglyceride and saturated monoglyceride contents e.g B7 and B10 and these are included in the National Annex to this European Standard (see 5.4.3) Table C.1 provides estimates for saturated monoglyceride contents based on market experience for finished EN 590 diesel fuel blends 18 BS EN

monoglycerides in pure FAME The saturated monoglyceride content of the FAME is calculated from measurements made by EN 14103 and EN 14105 The content of saturated fatty acid esters is calculated from intermediate results of EN 14103, the base model of which is described in Formula (C.1): µ SMG = µMG × µSATFA 100 (C.1) where µSMG is the saturated monoglyceride content, in % (m/m) µMG is the monoglyceride content as measured via EN 14105, in % (m/m) µSATFA is the total saturated fatty acid methyl esters (“SAT.FA”) content derived from EN 14103, in % (m/m) The industry developed a correlation between the saturated fatty acid methyl ester content and the cloud point of the FAME, which reads: µ SATFA = ((2,248CP ) + 17,657 ) (C.2) where is the cloud point in °C as measured via EN 23015 CP For the calculation of the saturated monoglyceride content, Formulae (C.1) and C.2 are combined as shown in Formula (C.3) The total monoglyceride content is determined independently by EN 14105 SMG = àMG ì ((2,248CP ) + 17,657 ) (C.3) 100 C.3 Calculation of EN 590 diesel fuel saturated monoglyceride content The final saturated monoglyceride content of the EN 590 blend can be estimated as follows: ì Bx àDSMG = 10 000 × µ SMG × ρFAME 100 000 (C.4) where µDSMG is the EN 590 diesel fuel saturated monoglyceride content, in (mg/l) μSMG is the content of saturated monoglycerides (“SMG”), calculated using Formula (C.3), in % (m/m) 19 BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) ρFAME is the FAME density at 15 °C in kg/m Bx is the volumetric blending percentage in diesel in % (V/V) EXAMPLE FAME cloud point: °C FAME monoglyceride content: 0,3 % (m/m) Using Formula (C.3), the FAME saturated monoglyceride content is 0,3 × (2,248 x + 17,657)/100 = 0,053 % (m/m) (530 mg/kg) FAME density for this example: 880 kg/m at 15 °C FAME saturated monoglyceride content, µSMG = (530 * 880)/1 000 = 466 mg/l A % volume blend in EN 590 would result in a saturated monoglyceride content of (466 × 7/100) = 33 mg/l This estimated value is then compared with the values stated in Table C.1 Taking into account the measurement uncertainty of this estimated value, this FAME could be fit for purpose when blended at % (B7) in all regions except Sweden and Nordic winter 20 BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) Bibliography [1] EN 14331, Liquid petroleum products - Separation and

Annex gives two specific climate-dependent requirements to comply with this standard These are; 100% FAME – Biodiesel complying with BS EN 14214 for use in diesel engines to comply with Subclause 5.4.1 of this standard 100% FAME – complying with BS EN 14214 for use as heating fuel engines to comply with Subclause 5.4.1 of this standard and FAME – used as a blend component in diesel fuel to BS EN 590 to comply with Subclause 5.4.3 of this standard FAME – as a blend component for heating fuel to comply with Subclause 5.4.1 of this standard NC.2 Requirements for 100% FAME The following grades shall apply at the retail pump or at delivery to the end user: Summer (16 March to 15 November inclusive): CFPP grade C Winter (16 November to 15 March inclusive): CFPP grade E NOTE 1 The date for the change from summer grade to winter grade will be reviewed in the light of experience NOTE 2 At the seasonal change-over points, the product should not be deemed to be out of compliance with this standard, providing it; i) complies with the previous season’s quality; and ii) is stored in a filling station tank to which fewer than three deliveries have been made since six weeks prior to the relevant sales date as above NC.3 Requirements for FAME used as a blend component The low temperature properties of a blend to BS EN 590 and of off-road automotive and heating oils to BS 2869 Classes A2 and D are specified individually within those British Standards For FAME to be blended into these grades, it has been demonstrated empirically (Annex C of this standard) that levels of saturated monoglycerides above a defined level will give rise to unacceptable operability performance in engines and heating plant Pending the development of methods for the direct determination of impurities, including saturated monoglycerides, as described in the Foreword to this standard, the following seasonal limits shall apply for the United Kingdom: 24 BS EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) Table NC3.1 – Climate dependent properties for blends of BS EN 590 containing FAME Property Unit Limits Min Test method Max Calculation: mg/l Saturated monoglyceride content BS EN 14214: Annex C: Equation [1] For the preparation of blends of BS EN 590 and BS 2869 Classes A2 and D to Summer quality 90 For the preparation of blends of BS EN 590 and BS 2869 Classes A2 and D to Winter quality 55 The calculation for the estimation of saturated monoglycerides is given at Annex C of this standard but is reproduced below in this National Annex in the interests of clarity The saturated monoglyceride content of the FAME is calculated from measurements made by EN 14103 and EN 14105 or is estimated via the following correlation between the cloud point (CP) of the FAME and the monoglyceride content, µMG: µSMG = µMG × ((2,248CP) + 17,657) 100 Equation [1] Where µSMG is the saturated monoglyceride content in mg/kg µMG is the monoglyceride content in % (m/m) as measured via BS EN 14105 CP is the cloud point °C as measured via BS EN 23015 The saturated monoglyceride content in mg/kg may then be converted to mg/l by multiplying by the FAME density NC3.1 Practical implications of the saturated monoglyceride specification The saturated monoglyceride values in Table are derived from values for the total monoglycerides and for the cloud point In practice these two properties can conveniently be specified in FAME for use in subsequent blending, rather than using a saturated monoglyceride value For blending of FAME into diesel fuels or heating oils at the maximum permissible value of 7.0%, selection of the following cloud point values from Table 3a and monoglyceride values from Table 3b of this British Standard may give the maximum flexibility in procurement These are presented in the form of a matrix for convenience, and demonstrate the permissible values for both summer and winter seasonality, at a range of concentrations in a finished blend of fuel B7

EN 14214:2012+A1:2014 EN 14214:2012+A1:2014(E) NC3.2 Selection of FAME for blending below the permitted maximum Saturated monoglycerides have been shown (Annex C) to be the predominant cause of poor low temperature operability in blended distillate fuels Furthermore, the degree of poor operability bears a direct relationship to the concentration of these saturated monoglycerides in the finished fuel A suitable strategy for optimal blend flexibility has been found to be for the control of saturated monoglycerides by the use of suitably dilute blends While not optimal for the incorporation of renewable fuel, this has enabled blenders to select more grades of FAME from Table of BS EN 14214, and to extend the scope of procurement The two examples below are for the use of a B5 blend (i.e 5% FAME in distillate fuel) and a B2 blend (i.e 2% FAME in distillate fuel) B5 Winter United Kingdom Grade a b a1 b1 c1 d1 e1 c2 d2 e2 d3 e3 e4 e5 e6 26 c d e B5 Summer United Kingdom f Grade a b c d e f
