1、Designation:D633116Standard Test Method forDetermination of Mass Concentration of Particulate Matterfrom Stationary Sources at Low Concentrations(ManualGravimetric Method)1This standard is issued under the fixed designation D6331;the number immediately following the designation indicates the year of
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 Precise and repeatable weighing procedures,1.2.2 Using low tare weight weighing dishes,1.2.3 Extending the sampling time at conventional samplingrates,or1.2.4 Sampling at higher rates at conventional samplingtimes(high-volume sampling).1.3 This test method differs from Test Method D3685/D3685M b
5、y requiring the mass measurement of filter blanks,specifying 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 fil
6、terblank.High volume sampling techniques or an extension of thesampling time may be employed to satisfy this requirement.This test method has tightened requirements on samplingtemperature fluctuations and isokinetic sampling deviation.This test method has eliminated the in-stack filtration tech-niqu
7、e.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.1.5 The values stated in SI units are to be regarded asstandard.No other units
