36、matter with nominal aerodynamic diameters of 10 m (PM10) and 2,5 m (PM2,5).This International Standard provides design guidelines for: the use of sampling cyclones, for the measurement of filterable particles; the measurement of filterable and condensable particles using the dilution sampling techni
37、que.The dilution sampling technique allows for the capture and measurement of condensable, secondary particulate matter that is similar in characteristics to materials formed when a flue gas exhaust mixes with ambient air. The method is suited for obtaining particulate speciation data useful in loca
38、l and regional source apportionment studies and health risk assessment studies.This International Standard provides for the use of two types of sampling train:a) a basic sampling train to measure filterable particles using sampling cyclones that can distinguish between particle sizes in the range of
39、 2,5 m and 10 m;b) a dilution sampling train that uses in-stack sampling cyclones to measure filterable in particles in the same manner as the basic sampling train as in a), but measures also, condensable particles with additional PM2,5and/or PM10cyclones located after the dilution chamber in the sa
40、mpling train.The method using dilution sampling for the formation, collection, and analysis of condensable particulate matter allows for capture of secondary particulate matter that is similar in character to ambient particulate matter. The method is suitable for the collection of source emission da
41、ta for local and regional source apportionment studies. Particulate speciation data may also be gathered using dilution sampling to provide data for health risk assessment studies.

It is the responsibility of the user of this document to establish appropriate safety and health practices and to dete
43、rmine the applicability of regulatory limitations prior to use.Collection of emission samples may require working on stack platforms and other elevated surfaces. Protective clothing (heavy long sleeves and pants, hard hats, and eye protection) should be worn at all times while working in the vicinit
44、y of hot surfaces. Insulated gloves should be worn when handling hot probes or accessing stack sampling locations with hot surfaces. Hearing protection should be worn if needed.Equipment cleaning requires the use of acetone. This work should be performed in a well-ventilated area to minimize fire an

46、pling technique, which simulates the interaction of stack gas components with the atmosphere as they mix after the stack exit.This International Standard provides for the use of two types of sampling train. Basic sampling train, a basic sampling train to measure filterable particles using sampling c
47、yclones that can distinguish between particle sizes in the range of 2,5 m and 10 m. This method is especially suitable for measurements of particle mass concentrations above 50 mg/m3as a half-hourly average at standard conditions (293 K, 1 013 hPa, dry gas) and applies to primary particulate matter
48、(PM) emissions equal to or less than an aerodynamic diameter of nominally 10 m (PM10) from stacks or ducts. Dilution sampling train, a dilution sampling train that utilizes a dilution chamber that mixes flue gas with conditioned dilution air to simulate the interaction of the stack gas components wi
49、th ambient air. This simulation process may lead to the condensation of particulate matter that might not otherwise be produced in the basic sampling train. The dilution sampling train uses in-stack sampling cyclones to measure filterable particles in the same manner as the basic sampling train, but in addition, utilizes additional PM2,5and/or PM10cyclones in the sampling train to measure particles formed in the dilution chamber.This method is intended for the measurement of m
