This European standard describes the determination of NOGE components with more than two aromatic rings (the two-ring NOGE is equal to BFDGE = Bis(2-hydroxyphenyl)methane bis(2,3-epoxypropyl)ether) and at least one epoxy group as well as their derivatives containing chlorohydrin functions and having a molecular mass less than 1000 Daltons in can coatings.
A high performance liquid chromatography (HPLC) method is employed based on reversed phase HPLC and fluorescence detection.
The method is capable of determining NOGE and its derivatives at a minimum level of 1 mg/ml in solution.
Direct HPLC analysis of the can coating extract may result in chromatograms difficult to interpret, due to interference from other components or the instability of the monomer resulting in a complex mixture of derivatives and/or reaction products. By forced hydrolysis of all epoxy groups and their reaction products, the quantification of the NOGE is simplified and the identities of the substances are indicatively confirmed.
NOTE   In this European standard the term “NOGE and its derivatives” refers to the requirements of Directive 2002/16/EC [1]. This includes NOGE components with more than two aromatic rings and at least one epoxy group as well as their derivatives containing chlorohydrin functions and having a molecular mass less than 1000 Daltons.

This European standard describes a method for the determination of BADGE, BFDGE and their reaction products in food simulants: distilled water, 3 % w/v aqueous acetic acid, 10 % v/v aqueous ethanol solution and olive oil or sunflower oil.
A high performance liquid chromatography (HPLC) method is employed based on reversed phase HPLC and fluorescence detection.
The method is capable of determining BADGE and its derivatives at a minimum level of 0,05 µg/ml food simulant.
BFDGE and its derivatives can be determined at a minimum level of 0,1 µg/ml food simulant.
Direct HPLC analysis of the migration solutions may result in chromatograms difficult to interpret, due to interference from other components or the instability of the monomers resulting in a complex mixture of derivatives and/or reaction products. By forced hydrolysis of all epoxy groups and their reaction products, the quantification of the relevant substances is simplified and in addition the identities of the substances are indicatively confirmed.
NOTE   In this European standard the term “BADGE, BFDGE and their derivatives” refers to the substances listed in Directive 2002/16/EC. These substances are listed in 4.1.

This document, part of EN 13130, specifies a procedure for the determination of 1,3-benzenedimethanamine (also known as 3-(aminomethyl)-benzylamine or m-xylylene diamine (m-XDA)) monomer, hereinafter referred to as m-XDA, in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and olive oil. The level of m-XDA monomer determined is expressed as milligrams of m-XDA per kilogram of food simulant in the above mentioned food simulants.
NOTE   In addition to the instability of m-XDA observed in olive oil, the test laboratory could not detect any
m-XDA peak from the olive oil work-up procedure. Based on some control checks, the assumption of the test laboratory was that the extraction from the olive oil does not work. Therefore, it is recommended that the food simulant 95 % ethanol or iso-octane be applied as substitute fatty simulants instead of olive oil.  It is believed that 95 % ethanol and iso-octane can be treated in the same way as 15 % v/v aqueous ethanol and olive oil simulant, respectively. Corresponding investigations were not possible within the project.

This European Standard describes test methods for the determination of the overall migration into fatty food simulants from plastics materials and articles, by total immersion of test specimens in a fatty food simulant at temperatures from 100 °C up to and including, 175 °C for selected times.  Also described is a procedure with a substitute test medium.  In this substitute procedure the mass of components adsorbed on modified polyphenylene oxide (MPPO) is taken as a measure for the assessment of the overall migration into olive oil.
NOTE 1   The total immersion test method has been written for use with the fatty food simulant, olive oil.  The test method can also be used with appropriate modifications with 'other fatty food simulants ' called simulant D - a synthetic mixture of triglycerides, sunflower oil and corn oil.  These other fatty food simulants will produce different chromatograms for the simulant methyl esters to those of the methyl esters of olive oil.  Select suitable chromatogram peaks of the methyl esters of the other fatty food simulants for the quantitative determination of the simulant extracted from the test specimens.
NOTE 2   A comparative migration test carried out with polypropylene and polyethylene terephthalate high temperature application containers as test samples at conditions 2 h at 100 °C and 2 h at 175 °C, respectively, in contact with 14C-labelled synthetic triglyceride and MPPO provided test results comparable within the analytical tolerance of the methods.
NOTE 3   To obtain reproducible and repeatable results using the MPPO method it may be necessary to measure the temperature of the test specimen before starting the migration period.  An appropriate method for measuring the temperature of the test specimen needs to be established.
The described methods are most suitable for food contact articles in the form of sheets and films, but can also be applied to a wide range of articles and containers.

This Technical Specification specifies test methods for 'alternative tests' and 'substitute tests' performed with volatile test media, iso-octane and a volume fraction of 95 % aqueous ethanol, for the determination of overall migration from polymeric coatings on paper and board intended to come into contact with fatty foodstuffs.
NOTE 1   It also includes guidance for the application of Council Directive 82/711/EEC [1], as last amended by Commission Directives  93/8/EC and  97/48/EC [2] [3] as regards the determination of the specific and overall migration into fatty food simulants (fat test) and includes a glossary to clarify the terminology used, see annex B.
NOTE 2   The iso-octane and a volume fraction of 95 % aqueous ethanol volatile test media used in these test methods are those specified for 'substitute tests' in Council Directive 82/711/EEC and its subsequent amendments. In addition to the use of iso-octane and 95 % v/v aqueous ethanol as test media for 'substitute tests', Council Directive 82/711/EEC and its subsequent amendments specifies the use of modified polyphenylene oxide as a test medium for use at temperatures of 100 °C and above.  A test method for overall migration from polymeric coatings intended to come into contact with fatty foodstuffs using modified polyphenylene oxide (MPPO) is in preparation.

This European Standard specifies two alternative test methods, in the sense of an extraction test with a 'more severe' test character, for the assessment of the overall migration into fatty food simulants.  
Method A is based on the determination of the extraction of migrateable substances from plastics which are intended to come into contact with foodstuffs, by total immersion in non-polar, iso-octane, and/or polar, ethanol, solvents depending on the polarity of the packaging material.  According to results obtained by this method (see [1],[2],[3],[4],[5],) and taking physio-chemical considerations into account, the obtained extraction efficiency has, generally, been found to be equivalent to or higher than overall migration results obtained under the test conditions, 10 days at 40 °C, 2 h at 70 °C, 1 h at 100 °C, 30 min at 121 °C and 30 min at 130 °C.
To ensure as complete as possible extraction of the potential migrants, a strong interaction, e.g. swelling, of the sample by the extraction solvent is necessary.  For this purpose, iso-octane is used as an extraction solvent for plastics materials and articles containing non polar food contact layers, such as polyolefins.  For test samples made from polar food contact plastics such as polyamide and polyethylene terephthalate, 95 % (v/v) aqueous ethanol is used.  For polystyrenes, plasticized polyvinyl chloride and other polymers where the identification or polarity of the polymer is not clear, two parallel extraction tests should be conducted using both of the proposed extraction solvents and taking the higher value obtained as the relevant result.
NOTE 1   In case of multilayer structures such as plastics laminates and co-extruded plastics, the nature of the food contact layer determines the selection of the extraction solvent(s).

This European Standard describes test methods for the determination of the overall migration into fatty food simulants from plastics materials and articles, by total immersion of test specimens in a fatty food simulant at any temperatures above 5 °C  up to and including, 175 °C for selected times.
When some plastics are tested by the methods in prEN 1186-2, prEN 1186-4, prEN 1186-6, prEN 1186-8, prEN 1186-12 and prEN 1186-13, the soxhlet extraction process does not achieve complete recovery of the absorbed olive oil from the test specimens.  In this method, the olive oil is released from the plastics test specimens by dissolving them in chloroform, toluene, xylene or tetrahydrofuran.
This method is suitable for plastics when exposure to olive oil is by total immersion as described in prEN 1186-2, in a cell, as described in prEN 1186-4, in a pouch, as described in prEN 1186-6, and by filling, as described in prEN 1186-8 and to tests carried out at low and high temperature, as described in prEN 1186-12 and prEN 1186-13.
This is provided the plastics are soluble in chloroform, toluene, xylene or tetrahydrofuran and insoluble in methanol and that whenever prEN 1186-2 is referred to in this method the appropriate clause of the relevant part of prEN 1186 is substituted.
The method may also be suitable for plastics which are only partially soluble in chloroform, toluene, xylene or tetrahydrofuran and insoluble in methanol.
NOTE 1   This test method has been written for use with the fatty food simulant, olive oil.  The test method can also be used with appropriate modifications with 'other fatty food simulants ' called simulant D - a synthetic mixture of triglycerides, sunflower oil and corn oil.  These other fatty food simulants will produce different chromatograms for the simulant methyl esters to those of the methyl esters of olive oil.
