SIST EN 13130-2:2004

Residues of terephthalic acid can be present in the plastics after processing to form materials and articles intended to come into contact with foodstuffs.
When these plastics are in contact with foodstuffs, the residual terephthalic acid monomer can migrate into the foodstuff. SIST EN 13130-2:2004

1 Scope This part of this European Standard specifies methods for the determination of the monomer terephthalic acid in food simulants; distilled water, 3 % (w/v) acetic acid aqueous solution, 15 % (v/v) ethanol aqueous solution and olive oil and other fatty food simulants, simulants D, e.g. a mixture of synthetic triglycerides or sunflower oil or corn oil.
The methods are capable of determining terephthalic acid in the food simulants at the level of the specific migration limit of 7,5 mg of terephthalic acid per kilogram of food simulants.
NOTE This method was developed for the determination of terephthalic acid in 15 % (v/v) aqueous ethanol, as required by the regulations in force at the time the development work was carried out.
However, this method, developed for 15 (v/v) aqueous ethanol, should be applicable to the determination in 10 (v/v) aqueous ethanol. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
For undated references the latest edition of the publication referred to applies (including amendments).

The olive oil test samples are extracted with dilute sodium hydrogen carbonate and the resultant aqueous solution is acidified and analysed by HPLC. 4 Reagents WARNING:
All chemicals are hazardous to health to a greater or lesser extent.
It is beyond the scope of this standard to give instructions for the safe handling of all chemicals, that meet, in full, the legal obligations in all countries in which this standard can be followed.
Therefore, specific warnings are not given and users of this standard shall ensure that they meet all the necessary safety requirements in their own country. NOTE During the analysis, unless otherwise stated, only reagents of recognized analytical grade and only distilled water of equivalent purity should be used. SIST EN 13130-2:2004
