ASTM D4539 Test Method for Filterability of Diesel Fuels by Low-Temperature Flow Test (LTFT)
1. Scope
1.1 This test method estimates 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 the standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is 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. For specific precautionary statements, see 7.1, 7.2.1, 7.3, 7.5, 7.9.3, 7.11, and A1.1.7.
