ASTM D7619-12a<\/h3>\n

Historical Standard: Standard Test Method for Sizing and Counting Particles in Light and Middle Distillate Fuels, by Automatic Particle Counter<\/h4>\n
\n

ASTM D7619<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method uses a specific automatic particle counter (APC) to count 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 the overall range from 4 \u00b5<\/span>m(c) to 100 \u00b5<\/span>m(c) and in the size bands \u2265<\/span>4 \u00b5<\/span>m(c), \u2265<\/span>6 \u00b5<\/span>m(c), and \u2265<\/span>14 \u00b5<\/span>m(c).<\/p>\n

Note<\/span> 1\u2014ASTM 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, D6985, D7467 and distillate grades of D396 and D2880.<\/p>\n

Note<\/span> 2\u2014For the purposes of this test method, water droplets are counted as particles, and agglomerated particles are detected and counted as a single larger particle. Dirt includes biological particles. Although the projected area of a particle is measured, this is expressed as the diameter of a sphere for the purposes of this test method.<\/p>\n

Note<\/span> 3\u2014The notation (c), used with particle sizes, is used to denote that the apparatus has been calibrated in accordance with ISO 11171. Strictly this only applies to particles up to 50 \u00b5<\/span>m.<\/p>\n

Note<\/span> 4\u2014This test method may be used for particle sizes bands up to 100 \u00b5<\/span>m(c), however the precision has only been determined for the size bands \u2265<\/span>4 \u00b5<\/span>m(c), \u2265<\/span>6 \u00b5<\/span>m(c), and \u2265<\/span>14 \u00b5<\/span>m(c). All measurements are per mL.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

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.<\/span><\/p>\n
