ASTM D4539 – Standard Test Method for Filterability of Diesel Fuels by Low-Temperature Flow Test (LTFT)
Description:
Significance and Use
5.1 The Low Temperature Flow Test results are indicative of the low temperature flow performance of the test fuel in some diesel vehicles (according to CRC Report No. 528). The test method is especially useful for the evaluation of fuels containing flow improver additives.
5.2 The test method can be used to supplement other measurements of diesel fuel low temperature behavior (in accordance with Test Methods D97, D2500, and D3117).
Scope
1.1 This test method covers estimating the filterability of diesel fuels in some automotive equipment at low temperatures.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.
