DIN EN 16329:2013-07 EN 16329:2013 (E) 4 Introduction This document specifi
21、es 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 showed improv
22、ed precision compared to EN 116:1997. The studies covered currently marketed fuels, including non-fossil components (FAME-blends) or biofuels. Although a bias has been identified during the statistical comparison of EN 116 and this document, this is not considered to be significant because the bias
23、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, but the results also showed indications of issues for fuel samples with a CFPP below 30 C. Further CEN studies are planned t
24、o assess the magnitude of these issues and the bias in additional market samples. A separate study is planned to further confirm the precision for paraffinic diesel fuels as the amount of these samples included in the Round Robin had been limited. A report with further statistical details of the Rou
25、nd Robin is under development within CEN. At the same time, EN 116 1 will be revised as well following conclusions from the Round Robin studies. DIN EN 16329:2013-07 EN 16329:2013 (E) 5 1 Scope This European Standard specifies an automated method for the determination of the cold filter plugging poi
26、nt (CFPP) of diesel and domestic heating fuels using linear cooling. This European Standard 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 engi
27、nes and domestic heating installations. The results obtained from the method specified in this European Standard 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 t
28、emperature 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 of
29、ten operate at a satisfactory level at temperatures somewhat lower than those indicated by the test results. WARNING The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is
30、 the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indis

33、ardized filtration device in a specified time, when cooled under standardized conditions DIN EN 16329:2013-07 EN 16329:2013 (E) 6 4 Principle This European Standard describes the use of automated test equipment only. A test portion of the fuel is cooled under the specified conditions and is drawn at
34、 intervals of 1 C into a pipette under a controlled vacuum of 2 kPa through a standardized wire mesh filter. The procedure is repeated, as the fuel continues to cool, for each 1 C below the first test temperature. Testing is continued until the amount of wax crystals, which have separated out of sol
35、ution, is sufficient to stop or slow down the flow so that the time taken to fill the pipette exceeds 60 s or the fuel fails to return completely to the test jar before the fuel has cooled by a further 1 C. The indicated temperature at which the last filtration was commenced is recorded as the cold
36、filter plugging point (CFPP). 5 Reagents and materials 5.1 Hydrocarbon solvents, technical grade, e.g. Heptane 5.2 Light hydrocarbon solvents, technical grade, e.g. Isopentane 5.3 Lintless filter paper, with particle retention of 30 m 5.4 Certified reference materials NOTE Certified reference materi
