ASTM E3193-21

5.1?This test method is intended for use with other standards that address the collection and preparation of samples (dusts by wipe, dried paint chips, and soils) that are obtained during the assessment or mitigation of lead hazards from buildings and related structures.

5.2?Laboratories analyzing samples obtained during the assessment or mitigation of lead hazards from buildings and related structures shall conform to Practice E1583, or shall be recognized for lead analysis as promulgated by authorities having jurisdiction, or both.

5.3?This test method may also be used to analyze similar samples from other environments such as toxic characteristic extracts of waste sampled using Guide E1908, and soil and sludge as prepared for analysis using U.S. EPA SW-846 Test Method 1311.

1.1?This test method covers the determination of lead (Pb) in dust by wipe, paint, and soil collected in and around buildings and related structures by flame atomic absorption spectrophotometry (FAAS) and is derived from Test Methods D4185 and E1613. For determination of lead (Pb) and other metals in air by FAAS, see Test Method D4185.

1.2?The sensitivity, detection limit, and optimum working concentration for lead (Pb) are given in Table 1.

1.3?The values stated in SI units are to be regarded as standard. No other values 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
