1、Designation: D7619 12bD7619 17Standard Test Method forSizing and Counting Particles in Light and Middle DistillateFuels, by Automatic Particle Counter1,2This standard is issued under the fixed designation D7619; the number immediately following the designation indicates the year oforiginal adoption
2、or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This test method uses a specific automatic particle counter2 (APC) to count
3、and measure the size of dispersed dirt particles,water droplets and other particles, in light and middle distillate fuel, and bio fuels such as biodiesel and biodiesel blends, in theoverall range from 4 m(c) to 100 m(c) 4 m(c) to 100 m(c) and in the size bands 4 m(c), 6 m(c), and 14 m(c). 4 m(c),6 m
4、(c), and 14 m(c).NOTE 1ASTM and military specification fuels falling within the scope of this test method include Specifications: D975 grades 1D and 2D, D1655,D3699, D4814 (see 14.1.1.1), D6751, D7467, distillate grades of D396 and D2880, MIL-DTL-83133, and MIL-DTL-16884.NOTE 2For the purposes of th
5、is test method, water droplets are counted as particles, and agglomerated particles are detected and counted as a singlelarger particle. Dirt includes biological particles. Although the projected area of a particle is measured, this is expressed as the diameter of a sphere forthe purposes of this te
6、st method.NOTE 3The notation (c), used with particle sizes, is used to denote that the apparatus has been calibrated in accordance with ISO 11171. Strictly thisonly applies to particles up to 50 m. 50 m.NOTE 4This test method may be used for particle sizes bands up to 100 m(c), 100 m(c), however the
7、 precision has only been determined for thesize bands 4 m(c), 6 m(c), and 14 m(c). 4 m(c), 6 m(c), and 14 m(c). All measurements are per mL.millilitre.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 This standard does
8、not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.1.4 This international standard was deve
