This practice covers the preparation of airborne particulate samples collected during the abatement of lead hazards for lead analysis in and around buildings and structures.

Formerly under the jurisdiction of Committee E06 on Performance of Buildings, this practice was withdrawn in January 2009 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

This practice is to be used for the digestion of airborne particulate lead that has been collected during various construction and renovation practices associated with lead abatement and removal in and around buildings and related structures. It may also be used to treat samples from other workplace environments where airborne lead is suspected to be present, for example, battery recycling, smelting, firing ranges, etc.

This practice may be used to prepare samples that have been obtained in order to ensure compliance with OSHA permissible exposure limits (PELs) for airborne lead concentrations.⁸

1.1 This practice covers the preparation of airborne particulate samples collected during the abatement of lead hazards in and around buildings and related structures.

1.2 This practice describes the digestion procedures for airborne particulate lead samples that are collected on cellulose ester membrane filters during abatement and construction activities. The practice is intended for use with airborne particulate lead samples that are prepared for subsequent analysis by laboratory-based quantitative analytical methods.

1.3 This practice covers the general considerations for quantitative sample digestion for total recoverable lead in airborne particulate using hot plate or microwave heating techniques.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 The following safety hazards caveat pertains only to the procedure section of this practice. 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. Specific hazard statements are given in Section 8 and Notes 2, 3, 8, and 10.
