This document specifies an isotopic method to control the authenticity of vinegar and food containing vinegar as an ingredient (for example Aceto Balsamico di Modena), with a density below 1,28 g/cm3. This method is applicable on acetic acid of vinegar (from wine, cider, agricultural alcohol, etc.) in order to characterize the botanical origin of acetic acid and to detect adulterations of vinegar using synthetic acetic acid or acetic acid from a non-allowed origin (together with the method described in EN 16466-2).
The isotopic analysis of the extracted acetic acid by 2H-NMR is based on a similar method already normalized for wine analysis [10].
The application of this document can involve the use of hazardous substances, operations and equipment. This document does not claim to address all associated safety issues. It is the responsibility of the user of this document to take appropriate measures for the safety and health protection of personnel before use, and to check the applicability of existing national and European rules and regulations.

This document specifies a method to determine the migration of substances from hardened cement based site-applied or site-formed materials (including pre-packaged mortars) into test waters after contact with the products. It also covers determination of migration from individual constituents of cement based products and materials (see Annex A and B) and from associated non-cement based products for approval purposes (see Annex C).
Site-applied or site-formed cement based materials which cannot be cast as cubes or prisms e.g. some spray applied systems, fall in the scope of EN 14944 −3 and not under this standard.
This document is applicable to site-applied or site-formed cement based materials intended to be used for the transport and storage of water intended for human consumption, including raw water used for the production of drinking water. It is also applicable to individual constituents of cement based products/materials and to associated non-cement based products/materials.
NOTE Tests with the specified test water will not necessarily be representative of materials used in different kinds of waters and especially very soft waters.

This document specifies a method to determine the influence of site-applied cement based materials and associated non-cement based products/materials (including pre-packaged mortars) on the odour, flavour, colour, turbidity and total organic carbon (TOC) of test waters after contact with the products.
This document is applicable to site-applied or site-formed cement based materials intended to be used for the transport and storage of water intended for human consumption, including raw water used for the production of drinking water. It is also applicable to individual constituents of cement based products/materials and to associated non-cement based products/materials.
Site-applied or site-formed cement based materials which cannot be cast as cubes or prisms e.g. some spray applied systems, should be tested as factory made cement based products according to EN 14944−1.
NOTE Tests with the specified test water will not necessarily be representative of materials used in different kinds of waters and especially very soft waters.
