In November 2018, the European Committee for Standardization (Comité Européen de Normalisation, CEN) published EN 646:2018'Paper and Board Intended to Come into Contact with Foodstuffs - Determination of Color Fastness of Dyed Paper and Board'.
This new standard supersedes its predecessor, EN 646:2006, and contains important changes. These include, inter alia, the following:
- Revising and extending the scope of food contact paper
- New definition for (unstained) glass fiber paper
- Replacing 'saliva simulant' with 'alkaline salt solution' for reagent
- Expanding the number of test condition procedures from two (A and B) to four (A to D)
- Evaluation only against gray scale
According to the new standard, conflicting national standards are to be withdrawn by May 2019 at the latest.
Major highlights of EN 646:2018 and a comparison with its predecessor, EN 646:2006, are summarized in Table 1.
