Over deze norm
1.1 This test method covers the determination of the mass of particulate contamination in a middle distillate fuel by filtration. This test method is suitable for all No. 1 and No. 2 grades in Specifications , , and and for grades DMA and DMB in Specification .
1.2 This test method is not suitable for fuels whose flash point as determined by Test Methods , or is less than 38 °C.
Note 1: Middle distillate fuels with flash points less than 38 °C have been ignited by discharges of static electricity when the fuels have been filtered through inadequately bonded or grounded membrane filter systems. See Test Methods and for means of determining particulate contamination in Specification aviation turbine fuels and other similar aviation fuels. See Guide for a more detailed discussion of static electricity formation and discharge.
1.3 This test method has not been validated for testing biodiesel, such as meeting Specification or blends of middle distillates and biodiesel, such as meeting Specification , or both. Test Method has been determined to be suitable for testing B100 and all blends of middle distillates and biodiesel.
Note 2: No. 1 and No. 2 grades in Specifications or currently allow up to 5% biodiesel meeting Specification . Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results.
1.4 The precision of this test method is applicable to particulate contaminant levels between 0 g/m3 to 25 g/m3 provided that 1 L samples are used and the 1 L is filtered completely. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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.
