Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2011); German version :2011
 N EN ISO 17072-2

Annotation

This part of ISO 17072 specifies a method for the determination of the total metal content in leather using digestion of the leather and subsequent determination with inductively coupled plasma/optical emission spectrometry (ICP/OES), or inductively coupled plasma/mass spectrometry (ICP/MS), or atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).

This method determines the total metal content in leather; it is not compound-specific or specific to the oxidation state of the metals.

The method is applicable for determining the following metals:

Aluminium (Al)

Antimony (Sb)

Arsenic (As)

Barium (Ba)

Cadmium (Cd)

Calcium (Ca)

Chromium (Cr) (except chromium-tanned leathers)

Cobalt (Co)

Copper (Cu)

Iron (Fe)

Lead (Pb)

Magnesium (Mg)

Manganese (Mn)

Mercury (Hg)

Molybdenum (Mo)
