2、original 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.Scope1.1 This test method2covers a method for the measurementof particulate
3、 matter(dust)concentration in emission gases inthe concentrations below 20 mg/m3standard conditions,withspecial emphasis around 5 mg/m3.1.2 To meet the requirements of this test method,theparticulate sample is weighed to a specified level of accuracy.At low dust concentrations,this is achieved by:1.
4、2.1 Exercising extreme care in weighing,1.2.2 Extending the sampling time at conventional samplingrates,or1.2.3 Sampling at higher rates at conventional samplingtimes(high-volume sampling).1.3 This test method differs from Test Method D3685/D3685M by requiring the mass measurement of filter blanks,s
5、pecifying weighing procedures,and requiring monitoring ofthe flue gas flow variability over the testing period.It requiresthat the particulate matter collected on the sample filter have amass at least five times a positive mass difference on the filterblank.High volume sampling techniques or an exte
6、nsion of thesampling time may be employed to satisfy this requirement.1.4 This test method may be used for calibration of auto-mated monitoring systems(AMS).If the emission gas containsunstable,reactive,or semi-volatile substances,the measure-ment will depend on the filtration temperature,and in-sta
7、ckmethods may be more applicable than out-stack methods forthe calibration of automated monitoring systems.1.5 The values stated in SI units are to be regarded as thestandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibilit
8、y of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3D1193 Specification for Reagent WaterD1356 Terminology Relating to Sampling and Analysis ofAtmosphere
