1.1This test method uses energy dispersive X-ray fluorescence (EDXRF) spectrometry for detection and quantification of lead (Pb) in paint layers, similar coatings, or substrates and homogenous materials. The following material types were tested in the interlaboratory study for this standard test method: ABS plastic, polyethylene, polypropylene, PVC, glass, zinc alloy, wood, and fabric.

1.2This technique may also be commonly referred to as High Definition X-ray Fluorescence (HDXRF) or Multiple Monochromatic Beam EDXRF (MMB-EDXRF).

1.3This test method is applicable for the products and materials described in 1.1 for a Pb mass fraction range of 14 to 1200 mg/kg for uncoated samples and 30 to 450 mg/kg for coated samples, as specified in Table 1 and determined by an interlaboratory study using representative samples

1.4Ensure that the analysis area of the sample is visually uniform in appearance and at least as large as the X-ray excitation beam at the point of sample excitation.

1.5For coating analysis, this test method is limited to paint and similar coatings. Metallic coatings are not covered by this test method.

1.6X-ray Nomenclature—This standard names X-ray lines using the IUPAC convention with the Siegbahn convention in parentheses.

1.7There are no known ISO equivalent methods to this standard.

1.8The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.9This 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.
