Significance and Use | ||||||||||
5.1 This test method may be used for quantitative determinations of Pb in painted and unpainted articles such as toys, children’s products, and other consumer products. Typical test time for quantification of Pb in homogenous samples is 1 to 3 min; and typical test time for quantification of Pb in paint is 4 to 8 min. |

1. Scope | ||||||||||
1.1 This 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. 1.2 This technique may also be commonly referred to as High Definition X-ray Fluorescence (HDXRF) or Multiple Monochromatic Beam EDXRF (MMB-EDXRF). 1.3 This 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 1.4 Ensure 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. 1.5 For coating analysis, this test method is limited to paint and similar coatings. Metallic coatings are not covered by this test method. 1.6 X-ray Nomenclature—This standard names X-ray lines using the IUPAC convention with the Siegbahn convention in parentheses. 1.7 There are no known ISO equivalent methods to this standard. 1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.9 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. |
