ASTM E1645-01

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

SCOPE
1.1 This practice covers the sample preparation procedures for paint samples that are collected during the assessment, management or control of lead hazards.
1.2 This practice describes the digestion procedures using a hot plate or microwave oven or apparatus for paint samples that are to be analyzed for lead content.
1.3 This practice covers the general considerations for quantitative sample extraction for total recoverable lead in dried paint samples (either bulk paint or paint powder) using hot plate or microwave heating techniques, or both.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This practice contains notes that are explanatory and not part of the mandatory requirements of the standard.
1.6 This practice is based on two NIOSH Methods, 7082 and 7105, and on an EPA standard operating procedure for lead in paint.
1.7 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.  For specific precautionary statements, see 6.2.4.4 and 7.2.1.
