Scope

5.1 This test method provides for analysis of Pb in applied paint using measurement times on the order of several minutes. It can be used to determine whether the sample of applied paint has an areal mass of Pb either substantially less than a specification limit, and therefore does not exceed it, or substantially above the specified limit, and therefore exceeds it.

5.2 If the value obtained with this test method falls close to a specification limit, a more precise test method may be required to positively determine whether Pb content does or does not exceed the specified limit.

1.1 This test method describes an energy dispersive X-ray fluorescence (EDXRF) procedure for determining the areal mass of Pb in mass per unit area in paint and similar coatings on common substrates of toys and consumer products, such as plastic, wood, steel, aluminum, zinc alloys or fabric.

1.2 This test method is applicable for homogeneous, single layer paint or similar coatings. The method does not apply to metallic coatings.

1.3 This test method is applicable for a range of Pb mass per unit area from 0.36 μg/cm² to approximately 10 μg/cm² for Pb in paint and similar coatings applied on common substrates. The lower limit of this test method is between 0.36 and 0.75 μg/cm² depending on the nature of the substrate. Based on the results obtained during the interlaboratory study (ASTM Report F40-1004), it is estimated that the applicable range of this method can be extended up to 50 μg/cm².

1.4 The values stated in SI units are to be regarded as standard. Values given in parentheses are for information only.

1.5 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.
