Standard Practice for Preparation of Dried Paint Samples by Hotplate or Microwave Digestion for Subsequent Lead Analysis

Significance and Use

Paint in buildings and related structures needs to be monitored for lead content in order to determine the potential lead hazard. Hence, effective and efficient methods are required for the preparation of paint samples that may contain lead.

This practice may be used for the digestion of paint samples that are collected during various lead-hazard control and risk assessment activities associated with lead abatement in and around buildings and related structures. This practice is also suitable for the digestion of paint samples collected from locations such as commercial buildings.

This practice may be used to prepare samples that have been obtained in order to ensure compliance with laws that govern lead content in paints.

This practice may be used to prepare samples that have been collected for risk assessment purposes.

This practice is intended for use with paint samples that are prepared for subsequent analysis by laboratory-based quantitative analytical methods.
