BS EN 116:2015

What is BS EN 116 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels about?

BS EN 116 specifies a method for the determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels (see 3.1) using automated test equipment. Manual test equipment may be used, but for referee purposes only automated test equipment is allowed.

BS EN 116 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.

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 satisfactorily at temperatures somewhat lower than those indicated by the test results.

Who is BS EN 116 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels for?

BS EN 116 on determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels is useful for:

• Petroleum industry
• Testing laboratories
• Research institutes/ academia
• Manufacturers of diesel engines and domestic heating installations

Why should you use BS EN 116 - Determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels?

The Cold Filter Plugging Point (CFPP) method is used to determine the low temperature operability of diesel fuels, biodiesel, blends, and gas oil. CFPP is an important property used to predict the minimum temperature at which fuel can freely flow through a filter in a diesel engine system.

BS EN 116 provides method for the determination of the cold filter plugging point (CFPP) of diesel and domestic heating fuels using automated test equipment with precision and accuracy.

The results obtained from the method specified in BS EN 116 are suitable for estimating the lowest temperature at which a fuel will give trouble-free flow in the fuel system.

The difference in results obtained using BS EN 116 from the sample “as received” and after heat treatment at 45°C for 30 min before the filtration may be used to investigate complaints of unsatisfactory performance under low temperature conditions.

What’s changed since the last update?

BS EN 116:2015 supersedes EN 116:1997. BS EN 116:2015 includes some technical changes with respect to EN 116:1997. These include:

• An automated method is described in detail beside the former manual procedure
• Scope and the precision statement have been changed based on a European Round Robin study including current available fuels for use in diesel engines. In addition, Fatty Acid Methyl Esters (FAME) and FAME blends in diesel have been checked
