2、esignation indicates the year oforiginal adoption 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 specific pa
3、rticle contaminationmonitors(PCMs)to count and measure the size of disperseddirt particles,water droplets and other particulates,in middledistillate fuel,in the overall range from 4 m to 70 m and inthe size bands 4 m,6 m,14 m,and 30 m.NOTE1The term particle contamination monitor,as used in this test
4、method,is the same as that defined in ISO 21018-4;an instrument thatautomatically measures the concentrations of particles suspended in a fluidat certain sizes and cannot be calibrated in accordance with ISO 11171whose output may be as a particle size distribution at limited sizes or asa contaminati

6、 the purposes of this test method,water droplets arecounted as particles,and agglomerated particles are detected and countedas a single larger particle.Dirt includes microbial particulates.Althoughthe projected area of a particle is measured,this is expressed as thediameter of a circle for the purpo
7、ses of this test method.The detector isunable to distinguish between dirt and water particles.NOTE4This test method may be used for particle sizes bands up to70 m,however the interim repeatability has only been determined for thesize bands 4 m,6 m,and 14 m.All measurements are counts permillilitre.1
