Nickel Migration (NIMS)

daps UKAS Logo
  • UKAS accredited proficiency testing scheme
  • The LGC NiMS Proficiency Testing scheme is designed to assess the performance of laboratories undertaking the determination of nickel release from articles intended to come into direct and prolonged contact with the skin according to the European Regulation (EC) 1907/2006.
  • The release of nickel from jewellery products, in close contact or pierced through the skin is the most widespread cause of allergic contact dermatitis - which affects an estimated 10% to 20% of the population.
  • Many ordinary items such as buttons, coins, spectacle frames, watchstraps and zips may also contain nickel and as such is hard for sufferers to avoid.
  • The method for the determination of nickel release from such products is defined in European standard EN 1811 (2011). The article to be tested is suspended in an artificial sweat solution for a period of a week, after which time the concentration of dissolved nickel in the solution is determined by ICP-MS or a similarly accurate and precise technique.
  • Scheme operates from January to December
