On 4 June 2015, the Nordic Council of Ministers (Norden) published a guide on "Food contact materials – metals and alloys, Nordic guidance for authorities, industry and trade" for metals and alloys used as food contact materials (FCM).
This Norden guide recommends those specific release limits (SRLs) for 21 metals from the technical guide on metal and alloy used in FCM  published by the Council of Europe (CoE) in 2013.
Article 3(1) of the Regulation (EC) No. 1935/2004 , Framework Regulation for FCM, states the general requirements for FCM. The migration of substances from FCM to food must not occur in amounts that could
endanger human health,
bring about an unacceptable change in the composition of food or
bring about a deterioration in the organoleptic characteristics of the food.
In the absence of specific requirements on the European level for metals and alloys used in FCM and articles, a technical guide was published by the CoE in 2013. The technical guide recommended SRL for 21 metals.
Since the technical guide published by the CoE is not legally binding for member states and serves as a reference for the implementation of Article 3(1) of Regulation (EC) No. 1935/2004, Norden published a guide to create a call for uniformed guide and interpretations across the Nordic countries: Denmark, Finland, Iceland, Norway and Sweden.
The Norden guide is meant to support compliance work in trade and industry, and as a tool for the official food inspection with regards to FCM composed of metals and alloys.
Table 1 shows an overview of the SRLs recommended by both the CoE and Norden.
