Significance and Use | ||||||||||
5.1 This test method has the advantage of extreme simplicity. It is a crude and non-specific test method, but it is useful in the study of long-term trends. It requires very little investment in equipment and can be carried out without a large technically-skilled staff. 5.2 This test method is useful for obtaining samples of settleable particulate matter for further chemical analysis 1.1 This test method covers a procedure for collection of dustfall and its measurement. This test method is not appropriate for determination of the dustfall rate in small areas affected by specific sources. This test method describes determination of both water-soluble and insoluble particulate matter. 1.2 This test method is inappropriate for industrial hygiene use except where other more specific methods are also used. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. |
