What is ISO 17072-1 - Extractable metals on leather about?
ISO 17072-1 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), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).
ISO 17072-1 is applicable for the determination of many extractable metals, including:
|
Aluminium (Al) Antimony (Sb) Arsenic (As) Barium (Ba) Cadmium (Cd) Calcium (Ca) Chromium (Cr) Cobalt (Co) |
Copper (Cu) Iron (Fe) Lead (Pb) Magnesium (Mg) Manganese (Mn) Mercury (Hg) Molybdenum (Mo) |
Nickel (Ni) Potassium (K) Selenium (Se) Tin (Sn) Titanium (Ti) Zinc (Zn) Zirconium (Zr) |
Who is ISO 17072-1 - Extractable metals on leather for?
ISO 17072-1 on Chemical determination of metal content by extractable metals on leather is applicable to:
- Leather manufacturer
- Leather testing laboratory
Why should you use ISO 17072-1- Extractable metals on leather?
ISO 17072-1 deal with extractable metals are found in various parts of the textile supply chain. Extractable metal is a metal that is released from the material under specific conditions and the specific condition in ISO 17072-1 is leather tanning which releases barium, arsenic, and chromium which can be used in the leather tanning process.
ISO 17072-1 is especially suitable for determining the extractable chromium in chromium-tanned leathers.
ISO 17072‑1 specifies test results and the quantification limits possible with ICP-OES are provided.
