Title:Aerospace - Particle Count Data Conversion and Extrapolation
Issuing Committee:A-6c1 Contamination And Filtration Committee
Scope: This Aerospace Information Report (AIR) describes a mathematical model that can be used to analyze particle count data. Particle counts that fit the model can be graphically displayed, converted from one counting size-frequency range to another, and extrapolated to estimate counts beyond the measured range. Derivation, applications and calculations are described. Cumulative particle counts larger than stated size-range are fitted against a modified log-normal distribution function by plotting on special log-log graph paper. Many real particle distributions approximate a straight line, showing good fit for this log-normal model. The resultant plot provides a basis for further analysis, including size-range conversion and extrapolation.【英文标准名称】:Firehazardtesting-Part10-3:Abnormalheat;Mouldstressreliefdistortiontest(IEC60695-10-3:2002);GermanversionEN60695-10-3:2002
