What are the standard reference materials for IVBA of lead?

Currently, the National Institute of Standards and Technology (NIST) Standard Reference Materials (SRM) 2710 and 2711 are used for quality assurance purposes when performing the IVBA method. Note that the original reference material (not the backup, for example 2710a) should be used as a control material. The backup material is from the same source and has been analyzed for concentration of contaminants; however, the bioaccessibility of lead in the backup material may differ from SRM 2710.
