Omfang

This European Prestandard specifies methods using flame atomic absorption spectrometry (FAAS) and inductively coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the ranges given in Table 1. Higher contents than those listed in Table 1 should be determined according to ENV 13800. Table 1 - Ranges of application for the determination of elements Element Ranges of applications (% m/m) FAAS ICP-ES Ag 0,00001 - 0,001 0,00001 - 0,001 Al 0,0001 - 0,005 0,00005 - 0,005 As 0,0002 - 0,005 0,00005 - 0,005 Bi 0,00005 - 0,0025 0,00005 - 0,0025 Ca 0,00005 - 0,001 0,00001 - 0,001 Cd 0,00005 - 0,001 0,00001 - 0,001 Co 0,00005 - 0,001 0,00005 - 0,001 Cr 0,00005 - 0,001 0,00005 - 0,001 Cu 0,00001 - 0,001 0,00001 - 0,001 Fe 0,00005 - 0,001 0,00005 - 0,001 Mg 0,00005 - 0,001 0,00005 - 0,001 Mn 0,00005 - 0,001 0,00005 - 0,001 Na 0,00005 - 0,001 0,00001 - 0,001 Ni 0,00005 - 0,001 0,00001 - 0,001 Sb 0,0002 - 0,0025 0,0002 - 0,0025 Se 0,0002 - 0,005 0,0002 - 0,005 Sn 0,0005 - 0,005 0,0002 - 0,005 Te 0,00002 - 0,0025 0,00002 - 0,0025 TI 0,00002 - 0,0025 0,00002 - 0,0025 Zn 0,00001 - 0,001 0,00001 - 0,001 These methods are intended as the definitive methods in case of dispute for the determination of elements at low content in lead. They are also recommended for the analysis of Certified Reference Materials (CRM) and Reference Materials (RM) which are used in analysis according to ENV 12908.
