1.1 This practice covers the evaluation of the performance of personal samplers of non-fibrous respirable aerosol. The samplers are assessed relative to a specific respirable sampling convention. The convention is one of several that identify specific particle size fractions for assessing health effects of airborne particles and in the setting of and testing for compliance with permissible exposure limits in the workplace and ambient environment. The conventions, which define inhalable, thoracic, and respirable aerosol sampler ideals, have now been adopted by the International Standards Organization (Technical Report ISO TR 7708), the Comite Europeen de Normalisation (CEN Standard EN 481), and the American Conference of Governmental Industrial Hygienists (ACGIH, Ref (1)), developed (2) in part from health-effects studies reviewed in Ref (3) and in part as a compromise between definitions proposed in Refs (3,4). This practice is specific to respirable aerosol sampler evaluation because of simplifying characteristics particular to this fraction.
1.2 This practice is complimentary to Test Method D 4532, which specifies a particular instrument, the 10-mm cyclone. The sampler evaluation procedures presented in this practice have been applied in the testing of the 10-mm cyclone as well as the Higgins-Dewell cyclone. Details on the evaluation have been recently published (5-7) and can be incorporated into revisions of Test Method D 4532.
1.3 Units of the International System of Units (SI) are used throughout this practice and should be regarded as standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
