Standard Practice for Field Collection of Dried Paint Samples for Subsequent Lead Determination

Importancia y uso:

5.1 Although this practice is intended for the collection of dried paint samples in and around buildings and related structures for the subsequent determination of lead content, this practice may also be used to collect paint samples from other structures for lead analysis.3

5.2 The variability associated with the sampling of dried paint is generally considered to be far higher than the variability associated with the analyses of the paint specimens. Therefore, it is essential that sample collection be properly controlled to produce representative and meaningful samples.

5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1645 or E1979 and determination of lead using laboratory analysis techniques such as inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method E3203) or flame atomic absorption spectrometry (FAAS) (see Test Method E3193).
