3、f dispersed dirtparticles,water droplets and other particles,in light and middledistillate fuel,and bio fuels such as biodiesel and biodieselblends,in the overall range from 4 m(c)to 100 m(c)and inthe size bands 4 m(c),6 m(c),and 14 m(c).NOTE1ASTM and military specification fuels falling within thes
4、cope of this test method include Specifications:D975 grades 1D and 2D,D1655,D3699,D4814(see 14.1.1.1),D6751,D7467,distillate grades ofD396 and D2880,MIL-DTL-83133,and MIL-DTL-16884.NOTE2For the purposes of this test method,water droplets arecounted as particles,and agglomerated particles are detecte
5、d and countedas a single larger particle.Dirt includes biological particles.Although theprojected area of a particle is measured,this is expressed as the diameterof a sphere for the purposes of this test method.NOTE3The notation(c),used with particle sizes,is used to denotethat the apparatus has bee
6、n calibrated in accordance with ISO 11171.Strictly this only applies to particles up to 50 m.NOTE4This test method may be used for particle sizes bands up to100 m(c),however the precision has only been determined for the sizebands 4 m(c),6 m(c),and 14 m(c).All measurements are per mL.1.2 The values
7、stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and
