适用范围：This European Standard is one in a series of standards for the determination of heavy metals in an aqueousextract of paper and paperboard intended for contact with food. This European Standard specifies the testmethod for the determination of mercury in an aqueous extract.It is applicable to paper and board with extractable mercury content exceeding 0,06 mg per kg.NOTE 1 The above limit of determination is 5 times below the actual limit existing today or proposed in Europe.NOTE 2 Mercury content levels below 0,06 mg per kg can be measured by this European Standard, if very sensitiveequipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.
