ASTM D4834-03(2014)

Standard Test Method for Detection of Lead in Paint by Direct Aspiration Atomic Absorption Spectroscopy

SIGNIFICANCE AND USE
4.1 Current U.S. regulations restrict the amount of lead that may be present in consumer paint products to less than 0.06 % based on the total solids. This test method provides a rapid means for screening paints to determine compliance with those regulations. The test method may be adjusted to meet regulations with a different limit on lead content.
SCOPE
1.1 This test method is intended as a screening test to determine if the solids in a paint contain more than 0.06 % lead. The test described can differentiate between 0.05 and 0.06 %. Paints giving a result greater than 0.05 % should be analyzed quantitatively for lead using Test Method D3335. This test method provides a more definitive and reliable screening test than Test Method D3618.  
1.2 There is no reason to believe that higher levels of lead could not be determined by this test method provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 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.

3.1 A weighed quantity of the paint sample is diluted (solvent-reducible paints in methyl isobutyl ketone and water-reducible
paints in water) and then aspirated into the burner of an atomic absorption spectrometer. Lead content of the paint is determined
from a calibration plot of absorbance versus concentration, prepared from standard coatings containing known amounts of lead.

4.1 Current U.S. regulations restrict the amount of lead that may be present in consumer paint products to less than 0.06 % based
on the total solids. This test method provides a rapid means for screening paints to determine compliance with those regulations.
The test method may be adjusted to meet regulations with a different limit on lead content.
