Content Introduction Development of the Biodiesel Standard Status Quo of EN 14214:2010 The new EN14214:2012 Summary
Introduction 1992 ASG was founded 1998 1st Accreditation for testing of fuels 2002: Extended approval for further solid fuel parameters 2003: Relocation to an own "tailor made" building 2006: Extension of the building to accommodate a mini plant laboratory 2012: Further extension of the building and new analytical methods
Development of the Biodiesel Standard - I At the beginning of the 1990s first industrial scale biodiesel plants were constructed and build. Biodiesel was mainly used in truck fleets as pure fuel (B100). Very soon it was recognised that it is absolutely necessary to have an own standard for the matrix biodiesel.
Development of the Biodiesel Standard - II In 1997 E DIN 51606 was introduced as a standard in Germany. Car manufactureres pushed the biodiesel industry in Germany to secure a better biodiesel quality because of problems in the field. As a consequence of this the AGQM was found in 1999.
Development of the Biodiesel Standard - III In October 2004 the European Standard EN 14214 came into force. The standard was revised a lot of times. Since November 2012 the actual version of EN 14214 is available.
Status Quo of EN 14214:2010 - I Parameter Method Limit Unit Ester content EN 14103 min. 96.5 % (m/m) Flash point EN ISO 2719 min 101 C CFPP EN 116 national limits C Water content EN ISO 12937 500 mg/kg Total contamination EN 12662 24 mg/kg Oxidation stability EN 14112 6,0 h Acid value EN 14104 0,50 mg KOH/g Linolenic acid ME EN 14103 12,0 % (m/m)
Status Quo of EN 14214:2010 - II Parameter Method Limit Unit Free glycerol content EN 14105 max 0,02 % (m/m) Monoglyceride content EN 14105 max 0,80 % (m/m) Diglyceride content EN 14105 max 0,20 % (m/m) Triglyceride content EN 14105 max 0,20 % (m/m) Total glycerol content EN 14105 max 0,25 % (m/m) Alkali metal content EN 14538 max 5 mg/kg Earth alkali metal content EN 14538 max 5 mg/kg
The new EN 14214:2012 - I expansion of the scope -> FAME as heating fuel remove of carbon residue increase of oxidation stability (min. 8,0 h) decrease of mono glyceride content max. 0,70 % (m/m) (B100) calculation of iodine value acc. to EN 16300 implementation of revised testing methods for ester content (EN 14103) and glycerol & glycerides (EN 14105) new requirements for FAME as blend component with respect to behavior at low temperature and the mono glyceride content (tables 3a and 3b)
The new EN 14214:2012 - II Table 3a Climatic classes for behavior at low temperatures Property Unit a b c Limits d e f Methods Cloudpoint C, max. 16 13 9 5 0-3 EN 23015 CFPP C, max. 13 10 5 0-5 -10 EN 116 a is only allowed in combination with class 1 (mono glyceride content).
The new EN 14214:2012 - III Table 3b Climatic classes for the mono glyceride content Property Mono glyceride content Unit % (m/m), max. 1 2 3 Limits 4 5 6 Methods 0,15 0,30 0,40 0,50 0,60 0,70 EN14105 Remark: 1 is designated for 100 % distilled FAME. Limit will be corrected after the development of an adequate testing method.
The new EN 14214:2012 - IV Climatic classes for Germany Date Values CP/CFPP [ C, max.] 15.04. 30.09. d 5 C / 0 C 01.10. 15.11. e 0 C / -5 C 16.11. 28.02. f -3 C / -10 C 01.03. 14.04. e 0 C / -5 C
The new EN 14214:2012 - V Example EN 14103 Ester content - Application range from C6 to C24 - new internal standard C19 ( animal fats)
Summary new EN 14214 is in force since February 2013 new/revised analytical methods are implemented (EN 14103, EN 14105, EN 16300, FprEN 16294, EN ISO 13032) especially the new climate classes are new for the whole market special situation in Germany old EN 14214 is relevant for acceptance of FAME with respect to the fulfillment of the national biofuel quota
