1、Designation: D4532 15Standard Test Method forRespirable Dust in Workplace Atmospheres Using CycloneSamplers1This standard is issued under the fixed designation D4532; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、 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 method provides details for the determinationof respirable dust concentration defined in terms of interna-tional

3、 convention in a range from 0.5 to 10 mg/m3inworkplace atmospheres. Specifics are given for sampling andanalysis using any one of a number of commercially availablecyclone samplers.1.2 The limitations on the test method are a minimumweight of 0.1 mg of dust on the filter, and a maximum loadingof 0.3

4、 mg/m2on the filter. The test method may be used athigher loadings if the flow rate can be maintained constant.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This test method contains notes that are explanatory andare n

15、ions of ISO 7708, EN 481,Guide D6062, and Ref. (1).4NOTE 1The definition of the respirable fraction is a compromisebetween previous definitions, available samplers, and the fraction of dustthat penetrates to (rather than deposits in) the alveolar region of the lung.Local legal definitions may differ

16、 from the definition adopted in this testmethod.3.2 For the terms and definitions related to characterizinguncertainty, see ISO GUM and Practice D7440.4. Summary of Test Method4.1 Air is drawn through a cyclone or equivalent samplerfollowed by a tared filter, which is then re-weighed to deter-mine t

17、he mass of respirable dust. The air flow rate and time ofsampling provide the volume from which the dust mass wassampled. A time-weighted average respirable dust concentra-tion is calculated by dividing the mass by the total air volume.NOTE 2Samplers alternative to a cyclone (for example, foam-based

18、 orpersonal cascade impactors) may be used if they have desirable properties(for example, ease of use or uncertainty control) for intended application.Nevertheless, this test method is limited to cyclone samplers.5. Significance and Use5.1 This test method covers the determination of respirabledust

19、concentration in workplace atmospheres.5.2 Variations of the test method are in world-wide use fordetermining compliance relative to occupational exposurelevels.5.3 The test method may be used to verify dust controlmeasures.5.4 The test method may also be applied in research intohealth effects of du

The sampling head consists of a cycloneand a filter assembly.6.1.1 Respirable Dust CycloneVarious types of respirabledust cy

21、clones are commercially available. In general, thesesamplers can be categorized into two groups, high flow ratecyclone samplers (flow rate range 4.2 10 L/min) and mediumflow rate cyclone samplers (flow rate range 1.7 2.75 L/min).High flow rate samplers should be considered for workplaceswhere airbor

24、the bias uncertaintyentirely by adopting a specific single sampler type, rather than theinternational sampling convention.13.3 Combined Standard Uncertainty and Expanded Uncer-tainty:13.3.1 The combined (relative) standard uncertainty (uc)isfound from pooling the uncertainties from each source:uc5 =
