9、5NOTE1CAN/CGSB-3.0,No.140.1-M86 is essentially equivalent toTest Method D4539,but the differences in apparatus and procedures mayor may not yield different results.3.Summary of Test Method3.1 The temperature of a series of test specimens of fuel islowered at a prescribed cooling rate.Commencing at a
10、 desiredtest temperature and at each 1C interval thereafter,a separatespecimen from the series is filtered through a 17-m screenuntil a minimum LTFT pass temperature is obtained.Theminimum LTFT pass temperature is the lowest temperature,expressed as a multiple of 1C,at which a test specimen can befi
11、ltered in 60 s or less.3.2 Alternatively,a single specimen may be cooled asdescribed under 3.1 and tested at a specified temperature todetermine whether it passes or fails at that temperature.4.Significance and Use4.1 The Low Temperature Flow Test results are indicative ofthe low temperature flow pe
