What is BS EN 16329 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using linear cooling about?
BS EN 16329 specifies an automated method for the determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using linear cooling.
BS EN 16329 is applicable to fatty-acid methyl esters (FAME) and to distillate fuels as well as paraffinic diesel fuels, including those containing FAME, flow-improvers or other additives, intended for use in diesel engines and domestic heating installations.
The results obtained from the method specified in BS EN 16329 are suitable for estimating the lowest temperature at which a fuel will give trouble-free flow in the fuel system.
Note: In the case of diesel fuels, the results are usually close to the temperature of failure in service except when the fuel system contains, for example, a paper filter installed in a location exposed to the weather or if the filter plugging temperature is more than 12 °C below the cloud point of the fuel. Domestic heating installations are usually less critical and often operate at a satisfactory level at temperatures somewhat lower than those indicated by the test results.
Who is BS EN 16329 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using linear cooling for?
BS EN 16329 on determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using linear cooling is useful for:
- Petroleum industry
- Testing laboratories  
- Research institutes/ academia  
- Manufacturers of diesel engines and domestic heating installations 
Why should you use BS EN 16329 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using linear cooling?
The cold filter plugging point is the highest temperature at which a given volume of fuel fails to pass through a standardized filtration device in a specified time when cooled under standardized conditions.
BS EN 16329 specifies in detail an automated method as an alternative technique to EN 116:1997 [1]. The cooling bath is no longer operated in several temperature stages (as in EN 116) but is replaced by a refrigeration unit with linear cooling.
Round Robin studies conducted for this determination method [2] specified in BS EN 16329 showed improved precision compared to EN 116:1997. The studies covered currently marketed fuels, including non-fossil components (FAME-blends) or biofuels.
Note: Although a bias has been identified during the statistical comparison of EN 116 and BS EN 16329, this is not considered to be significant because the bias is within the repeatability of both methods.
The range of CFPP values for the fuels for the Round Robin – therefore the basis of the determined precision – was from –47 °C to +11 °C.
BS EN 16329 lets you carry out a linear cooling method to determine the cold filter plugging point (CFPP) of diesel and domestic heating fuels with accuracy and precision.
