SAFEGUARDS | Hardgoods NO. 029/19
In November 2018, the European Committee for Standardization (Comité Européen de Normalisation, CEN) published EN 1104:2018 ‘Paper and board intended to come into contact with foodstuffs – Determination of the transfer of antimicrobial constituents’.
This new standard supersedes EN 1104:2005 and contains several important changes. These include, inter alia, the following:
- New definition for ‘Inhibition Zone’
- Modification of the composition for nutrient medium of Sabouraud
- Specifying the use of nine test pieces in total for tests with Bacillus Subtilis (clause 8.2.2)
According to the new standard, conflicting national standards are to be withdrawn by May 2019, at the latest.
Major highlights of EN 1104:2018 and a comparison with its 2005 version are summarized in Table 1.
