Organization: ASTM
Publication Date: 1 January 2019
Status: active
Page Count: 4
ICS Code (Other standards related to air quality): 13.040.99
ICS Code (Physicochemical methods of analysis): 71.040.50
scope:

This practice covers the extraction of lead (Pb) using ultrasonication, heat and nitric acid from a composited sample of up to four individual wipe samples of settled dust collected from equally-sized areas in the same space.

This practice contains notes which are explanatory and not part of mandatory requirements of the practice.

This practice should be used by analysts experienced in digestion techniques such as hot blocks. Like all procedures used in an analytical laboratory, this practice needs to be validated for use and shown to produce acceptable results before being applied to client samples.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.

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.
