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.
