Standard Test Method for
Detection of Lead in Paint by Direct Aspiration Atomic
Absorption Spectroscopy1

This standard is issued under the fixed designation D 4834; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. 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 D 3335.
This test method provides a more definitive and reliable
screening test than Test Method D 3618.

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 the
standard. The values given in parentheses are for information
only.

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.
