SCOPE 1.1 This method describes a procedure for determining the filter plugging tendency of diesel fuels at low temperature usually due to the for

29、mation of wax crystals (see Note after par. 6.1). 1.2 The method applies to all distillate diesel fuels. Fuels passing this test are expected to provide satisfactory fuel flow in automotive equipment at temperatures equal to or higher than that of the test. 1.3 This method is referenced and compared

30、 in ASTM D 4539. 1.4 The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to con

SUMMARY OF METHOD 3.1 The temperature of a series of 200 mL samples of test fuel is gradually lowered to the desired testing temperature at a controlled cooling rate of 1C/h. At 1C intervals, a sample

37、from the series is filtered through a 17 G28m screen at 20 kPa gauge vacuum. 3.1.1 This procedure is repeated until a sample from the series does not pass the test. The minimum pass temperature is the lowest temperature, expressed as a multiple of 1C, at which a minimum 180 mL of sample, when cooled

38、 under the prescribed conditions, can be filtered in 60 s or less. 3.2 Alternatively, a single sample may be cooled as described in par. 3.1 and tested at a specified temperature to determine if it passes or fails at that temperature. 4. SIGNIFICANCE AND USE 4.1 The Low Temperature Flow Test helps e

39、valuate the filterability of diesel fuels at low temperatures where wax plugging of diesel fuel systems can restrict the operation of automotive equipment. Fuels passing this test usually provide satisfactory flow performance at temperatures equal to or higher than the minimum LTFT temperature (refe

40、r to CRC Report No. 528). The test method is especially useful for evaluating fuels containing flow improver additives. 4.2 This test can be used as a measure of the flow performance of diesel fuels at low temperatures by petroleum refiners, marketers, distributors, consumers, and others concerned w

41、ith tailoring and handling diesel fuels for automotive use. 5. APPARATUS 5.1 Glass Bottles Several clear, heat-resistant, wide-mouthed bottles or tall form beakers having 240 to 300 mL capacity and 50 to 60 mm I.D. 5.2 Filtration Assembly as shown in Figure 1. 5.3 Filter as shown in Figure 2. The wi

42、re filter screen1(fine wire mesh cloth, 304 SS sintered screen) is a twill Dutch weave mesh with a nominal filtration rating of 17 G28m. The mesh is 65 wires/cm (165 wires/in.) by 303 to 315 wires/cm (770 to 800 wires/in.). The wire strands have diameters of 0.0071 cm (0.0028 in.) and 0.0046 cm (0.0

43、018 in.), respectively. The nominal filtration rating indicates a 98% removal by mass of all particles equal to or greater than 17 m. 5.4 Temperature Measuring Device Thermometer (type 114C for air baths or type 5C for liquid baths) calibrated under total immersion conditions, spanning the temperatu

44、re range of the test and calibrated in at least 0.5C increments, or a thermocouple or RTD thermister. 5.5 Cooling Bath capable of cooling multiple samples to the required temperature, in a controlled manner of 1.0 0.1C/h with a maximum deviation of 0.5C from the ramp, using either refrigerated air o

45、r liquid. The size and shape of the bath are optional. In an air bath, the air should circulate around all sides of the test jar, and the jar should sit on an insulating disk. When immersed in a liquid coolant, the top of the test jar should be at or below the liquid coolant level, the jar should no

46、t touch the sides of the well, and it should sit on an insulating disk. A lid or cover should be placed over the bottles during the cooling to prevent condensation. _ 1Bulk filter screen material not verified according to Appendix A is available in sheets from Pall Canada Limited, 7205 Millcreek Dri
