This document describes two representative methods for the determination of the extractable amount of specific primary aromatic amines (PAA) in a water extract of paper, board and pulp samples by means of HPLC with MS/MS detection which basically differ concerning the choice of the mobile and stationary phases. Deviating from this standard further methods may be applicable if it can be shown that comparable results can be achieved. A validation should be carried out by each laboratory.
It is applicable for the determination of the 22 primary aromatic amines (PAA) mentioned in the annex of Directive 2002/61/EC of 19th July 2002 amending Council Directive 76/769/EEC relating to restrictions on the market and use of certain dangerous substances and preparations (azocolourants) which are classified as carcinogenic categories 1A and 1B according to the CLP regulation and aniline.
The method described by this standard should be also applicable for the determination of further primary aromatic amines (PAA). A validation for every further analyte has to be done by the laboratory using this method.
The extractable amount of a primary aromatic amine (PAA) is expressed in mg PAA per litre water extract. This method is suitable for the determination of PAA with a working range of about 0,001 mg/l - 0,020 mg/l water extract.
Deviating from this standard further methods may be applicable if it can be shown that comparable results can be achieved. A validation should be carried out by each laboratory.

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,
-   0,25 mg per kg for chromium.
Metal content levels below those given can be measured by this document if very sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.

This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given.
Visual evaluation against a grey scale provides grading of the bleeding.
For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. It is advisable to check these samples using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in Annex A. If lower limit of detection is required, this procedure could also be used.

This document specifies an analytical test method for the determination of bisphenol A in solvent extracts of paper and board materials and articles intended to come into contact with foodstuffs using a high performance liquid chromatograph coupled to a fluorescence detector (HPLC-FLD).
This method can be applied to determine bisphenol A (see Table 1) in concentrations ranging from 0,025 mg/l to 2 mg/l in the solvent extracts, corresponding to 0,05 mg/kg to 4 mg/kg paper and board. The measurement range can easily be extended up to 40 mg/kg by adjusting the concentration factor of the solvent extract.

This document specifies an analytical test method for the determination of anthraquinone (see Table 1) in water and 95 % ethanol extracts of pulp, paper and board materials and articles intended to come into contact with foodstuffs using a gas chromatograph coupled to a mass spectrometer (GC-MS). Moreover, acetone extracts of modified polyphenylene oxide (MPPO) that, according to EN 14338, can be used as a simulant to assess the possible transfer/migration of substances from paper and board into dry, non-fatty foodstuffs can be analysed with the method presented here.
This method can be applied to determine anthraquinone in concentrations ranging from 2 μg/l to 40 μg/l in the water and solvent extracts, corresponding to 0,05 mg/kg to 1 mg/kg pulp, paper and board or, respectively, 0,1 μg/dm2 to 2 μg/dm2 in the case of migration tests with MPPO. The measurement range can be lowered by enriching anthraquinone from the water and solvent extracts.
