This PT is organised in support to Commission Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs.
The main objective of this exercise is to assess the analytical capabilities of nominated National Reference Laboratories (NRLs), food official control laboratories and other interested laboratories in the determination of heavy metals in chocolate.
Participation in EURL-HM-20 is mandatory for all NRLs having experience in this kind of analysis.

  • Registration for NRLs is free of charge.
  • Registration for other laboratories is 300 euros
