DIN EN ISO 17072-1:2017-09

This part of ISO 17072 specifies a method for the determination of extractable metals in leather using extraction with an acid artificial-perspiration solution and subsequent determination with inductively coupled plasma/optical emission spectrometry (ICP-OES), or inductively coupled plasma/atomic emission spectrometry (ICP-AES), or inductively coupled plasma/mass spectrometry (ICP-MS), or atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).This method is especially suitable for determining the extractable chromium in chromium-tanned leathers.This method determines extractable metals in leather; it is not compound-specific or specific to the oxidation state of the metals.
