Nickel Migration (NIMS)

"Our nickel migration proficiency testing programme: specific support for your nickel testing performance"

 

The release of nickel from jewellery is the most widespread cause of allergic contact dermatitis, which affects up to 20% of the general population. As many ordinary items may contain nickel – including buttons, coins, spectacle frames, watch straps, and zips - it can be difficult for sufferers to avoid.

 

NiMS, our Nickel Migration 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. 

 

The method for this determination is defined in European standard EN 1811, with the tested article suspended in an artificial sweat solution for a period of one week. The concentration of dissolved nickel in the solution is then determined by ICP-MS or a similarly accurate and precise technique. Successful participation in the NiMS Nickel Migration Proficiency Testing Scheme supports a laboratory’s quality systems by providing external and independent assessment of its performance.
