Specific release of elements from repeated use articles by CoE Resolution CM/Res(2013)9

Specific release of elements from repeated use articles according to the Council of Europe (CoE) Resolution CM/Res(2013)9 on metals and alloys used in food contact materials and articles.

In accordance with the resolution, specific release testing is performed using either 0.5% citric acid solution or artificial tap water prepared according to DIN 10531. The test is performed three times in succession, and compliance is evaluated based on the third migration. In addition, the sum of the first two migrations should not exceed the allowed exposure of one week of daily use (i.e., 7 x SRL, specific release limit).

This test also covers demands of the Nordic Council of Ministers (Norden) guideline TemaNord 2015:522 for metals and alloys intended for food contact.

The analysis includes the following metal and alloy components:

• Aluminium (Li)

• Antimony (Sb)

• Chromium (Cr)

• Cobalt (Co)

• Copper (Cu)

• Iron (Fe)

• Magnesium (Mg)

• Manganese (Mn)

• Molybdenum (Mo)

• Nickel (Ni)

• Silver (Ag)

• Tin (Sn)

• Titanium (Ti)

• Vanadium (V)

• Zinc (Zn)

As well as the analysis of the following contaminants:

• Arsenic (As)

• Barium (Ba)

• Beryllium (Be)

• Cadmium (Cd)

• Lead (Pb)

• Lithium (Li)

• Mercury (Hg)

• Thallium (Tl)
