This part of ISO 17072 specifies a method for the determination of the total metal content in leather usingdigestion of the leather and subsequent determination with inductively coupled plasma/optical emissionspectrometry (ICP-OES), or inductively coupled plasma/mass spectrometry (ICP-MS), or atomic absorptionspectrometry (AAS) or spectrometry of atomic fluorescence (SFA).This method determines the total metal content in leather; it is not compound-specific or specific to theoxidation state of the metals.The method is applicable for determining the following metals:Aluminium (Al) Copper (Cu) Potassium (K)Antimony (Sb) Iron (Fe) Selenium (Se)Arsenic (As) Lead (Pb) Silicon (Si)Barium (Ba) Magnesium (Mg) Sodium (Na)Cadmium (Cd) Manganese (Mn) Tin (Sn)Calcium (Ca) Mercury (Hg) Titanium (Ti)Chromium (Cr) (except chromium-tanned leathers) Molybdenum (Mo) Zinc (Zn)Cobalt (Co) Nickel (Ni) Zirconium (Zr)This method is also suitable for determining Boron (B) in leather.The quantification limit of total lead is 8 mg/kg (see Annex A).This part of ISO 17072 is not applicable to chromium-tanned leathers. In this case, ISO 5398-1, orISO 5398-2, or ISO 5398-3, or ISO 5398-4 are used.
