What is BS EN 14112 about?
BS EN 14112 specifies methods for determining oxidation stability of fatty acid methyl esters (FAME) at 110 °C, by means of measuring the induction period up to 48 h.
For induction periods higher than 8,5 h the precision is not covered by the precision statement of this method.
NOTE 1: EN 15751 describes a similar test method for oxidation stability determination of pure fatty acid methyl esters and of blends of FAME with petroleum-based diesel containing 2 % (V/V) of FAME at minimum.
NOTE 2: Limited studies on EN 15751 with EHN (2-ethyl hexyl nitrate) on FAME blends indicated that the stability is reduced to an extent which is within the reproducibility of the test method. It is likely that the oxidation stability of pure FAME is also reduced in the presence of EHN when EN 14112 is used for testing.
NOTE 3: For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction.
Who is BS EN 14112 for?
BS EN 14112 on FAME is relevant to:
- Biodiesel industry
- Food technologists
- Biochemical engineers
- Automotive industry
Why should you use BS EN 14112?
Oxidation stability- the chemical reaction that occurs with a combination of lubricating oil and oxygen, is an important biodiesel property.
BS EN 14112 helps users by specifying the accelerated oxidation test method to calculate and analyse the oxidation stability of FAME using manual and automated methods.
Overall, using the method specified by BS EN 14112 users will be able to monitor and control the quality of oxidation stability present in FAME. As a result, you will be able to avoid any compromise to fuel properties that degrade fuel quality and disrupt performance of the application where used.
