European Testing

Metals are used in many food contact materials, such as kitchen utensils, cutlery, serving plates, tins, pots, knives and so on. Some articles and objects intended to come into contact with food are made from pure metals while others are made from alloys or multilayers made from a metal and a different material. All materials and articles intended to come into contact with food must comply with the rules specified in Regulation 1935/2004/EC. Below testing is mainly concerned.

Metal and metal alloys(CM/Res(2013)9)
  • Extractable heavy metals in 0.5%citric acid or artifical tap water
LFGB (Germany) Metal and metal alloys
  • Extractable heavy metals in 0.5%citric acid or artifical tap water
  • Composition test of aluminum or aluminum alloy(optional,only for aluminum materials, not for aluminum coating)
  • Sensory test
DGCCRF (France)

The USA Testing

The metal material is request by FDA testing standard, USA 21 CFR, below is the main testing for metal parts.

Stainless steel(cooking purpose)
  • Cr content
Stainless steel
  • Composition test

  • Water extractives(wet or fatty foods except for alcoholic beverage)
  • n-heptane extractives(water in oil, or containing free oil or fat)
  • 8% ethanol extractives(alcoholic everage)
  • Extractable Pb
Metalware - brassware or metal ware made of copper or coated with copper (reference to CPG 7117.05 )
  • Extractable Pb
