| Official Journal of the European Union | EN L series ---|---|--- * * * | 2024/368 | 23.4.2024 ---|---|--- COMMISSION IMPLEMENTING DECISION (EU) 2024/368 of 23 January 2024 laying down rules for the application of Directive (EU) 2020/2184 of the European Parliament and of the Council as regards the procedures and methods for testing and accepting final materials as used in products that come into contact with water intended for human consumption (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive (EU) 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption (1), and in particular Article 11(2), point (c), thereof, Whereas: (1) | In order to be able to test and accept final materials to be used in products that come into contact with water intended for human consumption, hygiene requirements should be set out for each category of final material, namely organic, cementitious, metallic, enamels and ceramic, or other inorganic materials. The methodologies to be used should be based, inter alia, on Annex V to Directive (EU) 2020/2184 and should be taken into account in the performance of the conformity assessment procedures of products. ---|--- (2) | The testing of final materials requires the identification of relevant substances and other relevant parameters. Those substances and parameters should be analysed in the migration water. It is necessary to establish the requirements for such testing procedure and analysis. ---|--- (3) | This Decision should lay down the testing requirements in order to ensure the performance of the testing. For organic, cementitious, enamel and ceramic materials, the testing requirements should be subject to a risk-based approach by categorising the product that comes into contact with water intended for human consumption. The risk-based approach ensures proportionate testing in relation to the human health risk of the final material. ---|--- (4) | The testing for each final material should be carried out in accordance with the determined testing requirements to ensure that the water intended for human consumption is wholesome and clean. In order to determine whether the final material should be accepted and approved, it is necessary to set out pass/fail criteria that the results of the testing have to meet. ---|--- (5) | In order to ensure proportionate testing, it should be possible to reduce testing for materials used in minor components and minor components of assembled products. ---|--- (6) | National competent authorities or bodies should be allowed sufficient time to adapt their national system to the new requirements for testing and acceptance of final materials. The application of this Decision should therefore be deferred. ---|--- (7) | The measures provided for in this Decision are in accordance with the opinion of the Committee referred to in Article 22(1) of Directive (EU) 2020/2184. ---|--- HAS ADOPTED THIS DECISION: Article 1 The procedures and methods for testing and accepting final materials as used in a product as provided for in Article 11(2), point (c), of Directive (EU) 2020/2184 on the quality of water intended for human consumption are set out in the Annexes I to IV.

GENERAL PROCEDURE FOR TESTING AND ACCEPTING FINAL ORGANIC MATERIALS AS USED IN A PRODUCT. The procedure for testing and accepting final organic materials as used in a product includes the following steps: | Step 1 – Identification of relevant substances and relevant other parameters depending on: | 1. | Categorisation of products or components into risk groups and corresponding testing requirements ---|--- 2. | Formulation review ---|--- | Step 2 – Performance of tests | 1. | Migration test for | (a) | Total Organic Carbon (TOC) ---|--- (b) | Relevant substances ---|--- (c) | Unexpected substances ---|--- 2. | Modelling of migration of relevant substances ---|--- 3. | Migration test for | (a) | Odour and flavour ---|--- (b) | Colour and turbidity ---|--- 4. | Testing for Enhancement of Microbial Growth (EMG) ---|--- 5. | Testing residual content of substances ---|--- | Step 3 – Compliance with pass/fail criteria ---|--- 2\. IDENTIFICATION OF RELEVANT SUBSTANCES AND RELEVANT OTHER PARAMETERS 2.1. Categorisation of products or components into risk groups and corresponding testing requirements. For each product or component of an assembled product, a product group and a corresponding conversion factor (CF) shall be determined in accordance with Table 5. Based on the determined CF, the product or component is categorised in a risk group (RG) in accordance with Table 1. The categorisation in a RG determines the corresponding testing requirements including the relevant substances and relevant other parameters. The applicable testing procedure of final organic materials results from the use of these materials in products or components of assembled products. Minor components are considered to be components categorised in risk group 3 or 4 (RG3 or RG4) and for which reduced testing requirements, as set out in Table 1, may apply in comparison with the testing requirements for the risk group 1 or 2 (RG1 or RG2). For an assembled product, the components shall be determined. For each component in an assembled product, a product group shall be determined. If an assembled product consists of components made of the same main polymer, then the surface fraction of these components shall be cumulatively added for the determination of the product group in accordance with Table 5. Products or components made of multilayer materials are considered as one final material consisting of several layers. The testing shall be performed on the final materials as used in products in contact with water intended for human consumption. The specification in Table 1 for testing ‘on product or component’ means that the individual product or component of an assembled product shall be used for the performance of the testing. The specification in Table 1 for testing on ‘test piece of the formulation’ means that a representative test piece of the final material as used in a product or component can be considered for the testing. In this case it is not required that the individual product or component is tested.

Standards For testing the release of relevant substances, unexpected substances and TOC, the following standards shall be used to obtain the migration waters: (a) | For factory-made products: EN 12873-1:2014; ---|--- (b) | For site-applied materials: EN 12873-2:2021. ---|--- For testing odour and flavour, colour and turbidity, standard EN 1420:2016 shall be used to obtain the migration waters. The mentioned EN standards leave options for testing. The following provisions in sections 3.1.2, 3.1.3, 3.1.4 and 3.1.5 substantiate these standards. 3.1.2 Test piece For a product or a component of which the size does not allow the practical application of the testing, a representative test piece for the testing shall be provided. Special attention shall be given to the production of the test piece. 3.1.3. Temperature of testing All products shall be tested at 23 °C ± 2 °C (cold water test condition). Additionally, products that are normally used for warm or hot applications shall be tested at 60 °C ± 2 °C or 85 °C ± 2 °C, respectively. For this purpose, warm water corresponds to normal operating temperatures between 30 °C and 70 °C and hot water corresponds to operating temperatures exceeding 70 °C. Multilayer products shall always be tested at 60 °C ± 2 °C or 85 °C ± 2 °C additionally, even when not used at these temperatures. 3.1.4. Type of test water Cold water test (23 °C ± 2 °C) shall be performed with chlorinated and non- chlorinated test water. In case a warm or a hot water test is required, this test shall only be performed with non-chlorinated test water. 3.1.5. Migration periods For cold water tests the migration samples of the 1st, 2nd and 3rd migration period according to standards shall be analysed. The compliance with the pass/fail criteria shall be assessed at the 3rd migration period (10th day of testing). If the pass/fail criteria set out in sections 4.2 and 4.3 are not met at the 3rd migration period the testing can be extended and the 5th, 7th and 9th period shall be analysed additionally. In this case the pass/fail criteria shall be assessed at the 9th migration period (31st day of testing). For warm or hot water tests the migration samples of the 1st, 6th and 7th migration period shall be analysed. The compliance with the pass/fail criteria shall be assessed at the 7th migration period (10th day). If the pass/ fail criteria set out in sections 4.2 and 4.3 are not met at the 7th migration period the testing can be extended and the 12th, 17th and 22nd period shall be analysed additionally. In this case the pass/fail criteria shall be assessed at the 22nd migration period (31st day). For multilayer products an extended warm or hot water migration test is always required to ensure that substances originating from different layers appear in the migration water. To ensure sufficient substance diffusion and equilibration across layer boundaries, it is required that the multilayer product has undergone a storage period at room temperature for at least 30 days. 3.2. Analysis of migration waters 3.2.1. Relevant Substances The relevant substances defined in section 2.2.2 shall be analysed in the migration waters (see section 3.1.5). The methods for analysis of relevant substances in migration waters shall be validated and documented in accordance with EN ISO/IEC 17025:2017 or other equivalent standards accepted at international level. 3.2.2. Unexpected Substances Unexpected substances are only determined in the migration waters of the cold water test. For the identification and semi-quantitative analysis of unexpected substances a GC-MS screening shall be conducted according to EN 15768:2015. 3.2.3. Relevant other parameters The relevant other parameters shall be analysed in the migration waters according to the following standards: (a) | Total Organic Carbon (TOC) shall be determined according to EN 1484:1997 as non-purgeable organic carbon; ---|--- (b) | Odour shall be determined as Threshold Odour Number (TON) according to EN 1420:2016 and EN 1622:2006; ---|--- (c) | Flavour shall be determined as Threshold Flavour Number (TFN) according to EN 1420:2016 and EN 1622:2006; ---|--- (d) | Colour shall be determined according to EN ISO 7887:2011 – method C; ---|--- (e) | Turbidity shall be determined according to EN ISO 7027-1:2016 - nephelometry. ---|--- 3.3. Mathematical modelling Where generally recognised diffusion models exist on the basis of experimental data, mathematical modelling for estimation of migration levels may be used as alternative to the migration testing of relevant substances for certain types of final organic materials. If these recognised diffusion models predict that the migration of the substance complies with the maximum tolerable concentration at the tap (MTCtap), migration testing for these substances is not necessary. For the assessment of some parameters and for modelling, the content of the respective substances in the final material shall be determined. If compliance is not shown by using the models, migration testing shall be performed. The following mathematical modelling approaches may be used: (a) | Migration modelling according to CEN/TR 16364:2012 or other equivalent standards accepted at international level, simulating a migration test according to the EN 12873-1:2014 and EN 12873-2:2021; ---|--- (b) | Full transfer calculation, simulating full transfer of substances from the product into the migration water. ---|--- 3.4. Enhancement of Microbial Growth (EMG) testing For the EMG testing, standard EN 16421:2015 – method 1 or 2 shall be used. 3.5. Testing residual content of substances (QM/QMA) For starting substances with a maximum quantity (QM or QMA) restriction set out in the European positive list of starting substances for organic materials of Annex I of Commission Implementing Decision (EU) 2024/367, its residual content in the product shall be analysed. 4\.

GENERAL PROCEDURE FOR TESTING AND ACCEPTING The procedure for testing and accepting final enamels, other glass materials, ceramic materials and other inorganic materials as used in a product includes the following steps: | Step 1 – Identification of relevant substances and relevant other parameters depending on: | 1. | Categorisation of products or components into risk groups and corresponding testing requirements. ---|--- 2. | Composition review ---|--- | Step 2 – Performance of tests | 1. | Testing of composition ---|--- 2. | Migration test for relevant substances ---|--- | Step 3 – Compliance with pass/fail criteria ---|--- 2\. IDENTIFICATION OF RELEVANT SUBSTANCES AND RELEVANT OTHER PARAMETERS 2.1. Categorisation of products or components into risk groups and corresponding testing requirements. For each product or component of an assembled product, a product group and a corresponding conversion factor (CF) shall be determined in accordance with Table 5 of Annex I. Based on the determined CF, the product or component is categorised in a risk group (RG) in accordance with Table 1. The categorisation in a RG determines the corresponding testing requirements including the relevant other parameters. The applicable testing procedure of final materials results from the use of these materials in products or components of assembled products. Minor components are considered to be components categorised in risk group 4 (RG4) and for which reduced testing requirements, as set out in Table 1, may apply in comparison with the testing requirements for the risk group 1, 2 or 3 (RG1, RG2, RG3). For an assembled product the components shall be determined. For each component in an assembled product, a product group shall be determined. If an assembled product consists of components made of the same final material, then the wetted surface fraction of these components shall be cumulatively added for the determination of the product group in accordance with Table 5 of Annex I. The testing shall be performed on the final materials as used in products in contact with water intended for human consumption. Table 1 Risk-based testing requirements for products or components of assembled products Risk group | Conversion factor CF in d/dm | Composition review & testing | Specific migration testing ---|---|---|--- RG 1 | ≥ 4 | Yes | Yes, on product or component. Enamels: test piece(s) produced by enameller RG 2 | ≥ 0,4 and < 4 RG 3 | ≥ 0,04 and < 0,4 | Yes | Yes, on product or component. Enamels: test pieces(s) produced by enamel manufacturer RG 4 | < 0,04 | Yes | No 2.2. Composition review 2.2.1. Required information For the final materials the complete composition with the range for all constituents exceeding 0,02 % (m/m) is required. The content of lead and cadmium shall be declared. 2.2.2. Accepted compositions The compositions of the final materials shall comply with compositions listed in the European positive lists of compositions of enamels, ceramics and other inorganic materials set out in Table 1 of Annex IV of Commission Implementing Decision (EU) 2024/367, and fulfil the limitations set out in this European positive list in respect of their use for certain product groups and the use of these products. The content of lead and cadmium shall be less than 0,02 % (m/m). 2.2.3. Relevant substances The relevant substances to be analysed in migration waters are specified for each composition set out in the Annex IV to Commission Implementing Decision (EU) 2024/367. 3\. TESTING REQUIREMENTS 3.1. Testing of the composition An analysis of the composition of the final materials shall be performed to verify compliance with the compositional requirements of compositions of enamels, ceramics or other inorganic materials included in the Annex IV to Commission Implementing Decision (EU) 2024/367. 3.2. Migration testing 3.2.1. Standards For testing the release of relevant substances, the following standard shall be used to obtain the migration waters: EN 12873-1:2014. The following sections 3.2.2, 3.2.3, 3.2.4 and 3.2.5 substantiate this standard. 3.2.2. Test piece Special attention shall be given to the production of the test piece. The respective component or product is to be used as test piece(s). A specifically produced test piece shall only be used if the product cannot be tested. 3.2.3. Temperature of testing All products shall be tested at 23 °C ± 2 °C (cold water test condition). Additionally, products that are normally used for warm or hot applications shall be tested at 60 °C ± 2 °C or 85 °C ± 2 °C, respectively. For this purpose, warm water corresponds to normal operating temperatures between 30 °C and 70 °C and hot water corresponds to operating temperatures exceeding 70 °C. For materials that can be subjected to high temperature variation (for example, in solar water heaters), the test should be carried out at 85 °C. 3.2.4. Type of test water Cold water test (23 °C ± 2 °C) shall be performed with non-chlorinated test water. In the case PAH analysis is required the test shall be performed with chlorinated test water additionally. In case a warm or a hot water test is required, the test shall only be performed with non-chlorinated test water. 3.2.5. Migration periods For cold water tests the migration samples of the 1st, 2nd and 3rd migration period according to standards shall be analysed. The compliance with the pass/fail criteria shall be assessed at the 3rd migration period (10th day of testing). If the pass/fail criteria (see 4.2 and 4.3) are not met at the 3rd migration period, testing can be extended and the 5th, 7th and 9th period shall be analysed additionally. In this case the pass/fail criteria shall be assessed at the 9th migration period (31st day of testing). For warm or hot water tests the migration samples of the 1st, 2nd, 3rd and 7th, migration period shall be analysed. The compliance with the pass/fail criteria shall be assessed at the 7th migration period (10th day). If the pass/ fail criteria (see 4.2 and 4.3) are not met at the 7th migration period, testing can be extended and the 12th, 17th and 22nd period shall be analysed additionally. In this case the pass/fail criteria shall be assessed at the 22nd migration period (31st day). 3.3. Analysis of migration waters 3.3.1. Relevant Substances The methods for analysis of relevant substances in migration waters shall be validated and documented in accordance with EN ISO/IEC 17025:2017 or other equivalent standards accepted at international level. 4\. ACCEPTANCE REQUIREMENTS: PASS/FAIL CRITERIA 4.1. Composition The analysed composition of the final material shall comply with the compositional requirements and other limitations specified in the respective European positive list of compositions. 4.2. Relevant substances 4.2.1. Conversion of test results In accordance with the standard EN 12873-1:2014, the test results are expressed as migration rates (M) in μg/(dm2.d). These results shall be converted to estimate the concentrations at the tap (Ctap), defined as Ctap = M * CF, where CF is the corresponding conversion factor in d/dm. The conversion factors for the different product groups are listed in Table 5 of Annex I. 4.2.2. Pass/fail criteria for relevant substances The following requirements shall apply to the cold water migration test: (a) | Ctap ≤ MTCtap for the 3rd migration period (10th day of testing) or, in case extended testing is needed, at the 9th migration period (31st day of testing); ---|--- (b) | there shall be no increasing trend of Ctap in time. ---|--- The following requirements shall apply to the warm/hot water migration test: (a) | Ctap ≤ MTCtap for the 7th migration period (10th day of testing) or, in case extended testing is needed, at the 22nd migration period (31st day of testing); ---|--- (b) | there shall be no increasing trend of Ctap in time. ---|--- The measured substance concentrations in the migration water from the successive migration periods shall be used to assess the trend. However, if Ctap in the relevant migration period is below 1/10 of MTCtap, no trend analysis is required. The MTCtap,inorganic to be applied are defined in the Annex IV and Table 1 of Annex V to Commission Implementing Decision (EU) 2024/367. * * * ELI: http://data.europa.eu/eli/dec_impl/2024/368/oj ISSN 1977-0677 (electronic edition) * * *
