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.
