Standard Test Method for Determination of Lead by Graphite Furnace Atomic Absorption Spectrometry (GFAAS) Techniques

Importancia y uso:

5.1 Environmental (including workplace) samples obtained during the assessment or mitigation of lead hazards from buildings and related structures are analyzed to determine lead content in media of concern. This test method is intended for use with other ASTM standards (see 2.1) that address the collection and preparation of samples (airborne particulate, dusts by wipe and micro-vacuuming, dried paint chips, and soils) that are obtained during the assessment or mitigation of lead hazards. This test method may be used to analyze samples collected from various environments, such as workplaces, buildings, indoor or outdoor settings, construction sites, housing, and so on.

5.2 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 (5).

5.3 This test method can be relied upon by laboratories seeking accreditation for lead analysis by means of GFAAS.
