Abstract
This European Standard is one in a series of Standards for the determination of heavy metals in an aqueous extract of paper or board intended for contact with food. This European Standard specifies the test method for the determination of cadmium and lead in an aqueous extract.
It is applicable to paper and paperboard with extractable metal contents exceeding
- 0,1 mg per kg for cadmium;
- 0,6 mg per kg for lead.
NOTE 1 The above limits of determination are achieved by multiplying the actual limits existing today or proposed in Europe by 0,2.
NOTE 2 Metal content levels below those given can be measured by this European Standard if very sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.
