1.1This test method is intended as a screening test to determine if the solids in a paint contain more than 0.5 % lead. The test described barely detects the presence of 0.4 % but gives a definite positive result at the 0.5 % level.

Note 1:This test method may be used to detect the presence of lead at concentrations higher or lower than 0.5 % by making appropriate changes in the specimen size and reagent quantities specified.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3Paints giving an unexpected positive or questionable result should be analyzed quantitatively for lead, using Test Method D3335.

1.4This 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. Specific hazard statements are given in Section 7.

1.5This 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.
