ISO 17072-1 Leather - Chemical Determination of Metal Content - Part 1: Extractable Metals

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 17072-1 testing. This standard specifies a method for the determination of extractable metals in the skin using extraction with an acid artificial sweat solution followed by inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), atomic determination .

ISO 17072-1 Leather - Chemical Determination of Metal Content - Part 1: Extractable Metals

This method determines the extractable metals in the leather; It is not compound specific or specific to the oxidation state of the metals. This method is particularly suitable for determining extractable chromium in chrome-tanned leathers.

A skin sample is ground and extracted in acid perspiration solution at 37°C ± 2°C for 4 hours ± 5 minutes. The extract solution is filtered, acidified and analyzed with ICP or SFA or AAS.

If the piece of leather available for testing is a whole hide or leather, the test specimens shall be sampled according to the standard procedures given in ISO 2418. If sampling according to ISO 2418 is not possible (for example, if leathers are from finished products, such as shoes or clothing), details of sampling shall be given in the test report.

Grind the leather sample according to ISO 4044. Wet (more than 30% humidity) test pieces should be pre-dried for at least 50 hours at a temperature not exceeding 2 °C ± 12 °C. The drying temperature should be chosen taking into account the effect of high temperature on the nature of the analyte.
