Surfaces of materials and coatings shall be durable, cleanable and where required capable of being disinfected, without

16、 breaks, resistant to cracking, chipping, flaking and abrasion and prevent penetration of unwanted matter under intended use. NOTE This subclause corresponds to 5.2.1 of EN 1672-2:2005. 3.1.3 In addition to the general requirements (see 3.1.2), under intended conditions of use, the materials shall b

17、e: corrosion resistant; non toxic; non absorbent (except when technically or functionally unavoidable). The materials shall: not transfer undesirable odours, colours or taint to the food; not contribute either to the contamination of food or have any adverse influence on the food. NOTE This subclaus

18、e corresponds to 5.2.2 of EN 1672-2:2005. 3.2 Example list of considerations to be taken into account at each stage of the flow chart (see Figure 2) a) Consider the nature of the food and physical environmental conditions: description of the food coming into contact with the surface in the food area

19、: type of food (vinegar, salted products, fruit juice, sausage, presence of abrasives particles, stones of fruits, tough powder, etc.); type of additives (citric acid, acetic acid, colorants, etc.); CEN/TR 15623:20086 composition of the elements in contact: pH of the food product; combined with high

20、 level of salt, with high temperature; quality of water (TH, CaCO3, Fe, Cl, etc.); presence of pieces of food, flour, etc; description of the cleaning and disinfecting products: composition of the cleaning and disinfecting agents; parameters during cleaning and disinfecting (time, concentration and

21、pH, temperature, flow rate, etc; temperature: during production time; during cleaning time; humidity of the environment. b) Consider the conditions of production, cleaning, disinfection and/or sterilisation: conditions of circulation, agitation (speed, turbulence); thermal stress (hot, cold, cycling

22、); pressure stress; radiation (Ultra Violet, Infra Red, etc.); mechanical erosion (mixing, scraping); chemical corrosion; condensation. c) Consider the material: type of materials (metals, alloys, plastics, rubbers, etc.); structure and composition; corrosion (galvanic, pitting, stress, etc.); state

23、 of the material at the delivery (relief treatment, temper, etc.); surface treatment (mechanical, electrolytic, thermal, coating, etc.); stress zone (welding area, deflection, etc.). d) Consider the need for testing (corrosion tests, qualification of thermal or chemical treatment, mechanical propert

24、ies, cleanability, etc.). CEN/TR 15623:20087 4 Legal and normative references for materials The Regulation (EC) No. 1935/2004 entry into force on 6 December 2004 (20 days after publication) and 27 October 2006 in the case of article 17 on traceability requirements. This regulation repeals directives

25、 80/590/EEC and 89/109/EEC. Also the Regulation 2023/2006 is published. The main content is defined below. The recourse to regulations as a legal instrument for execution provisions, in place of specific execution provisions, will allow provisions to be applied in a uniform manner throughout the Eur

26、opean Union. A regulation need not be transcribed into national law for it to become applicable. The inclusion of “active and intelligent materials and articles”. The procedure for the authorisation of new substances and for their addition to an existing positive list is detailed. Request is to be s

27、ubmitted to the relevant national authority which informs and forwards the application to the European Food Safety Authority (EFSA instituted by regulation EC no. 178/2002). EFSA informs the other member states and the Commission, checks the validity of the dossier and must issue an opinion within s

28、ix months (possibly 6 months more with justification). It should also be noted that there will be general access to applications except for parts which are clearly marked as and accepted as being confidential (Article 20 of the Regulation). NOTE Guidance on the administrative and technical data requ

29、ired and on the format for formal submissions is available on the EFSA website address (see Annex A). Requirements for establishing systems for good manufacturing practices (GMP) are introduced for materials intended to come into contact with food. NOTE Regulation 2023/2006 applies from 1stAugust 20

30、08. Traceability requirements for materials and articles intended to come into contact with food are provided in article 17 (see also consideration 18). Specific safeguarding measures for materials and articles intended to come into contact with food are provided in article 18. These may be taken by

31、 a member state, should circumstances so require it, in the event of a risk to human health. Reference laboratories: A community reference laboratory and several national reference laboratories shall be designated according to article 24 (see also consideration 23). New materials that may be subject

32、 to specific directives: In addition to “active and intelligent materials and articles”, there are plans to add two additional groups of materials, these being ion exchange resins and glues. Annex 1 of the regulation 1935/2004 gives a list of groups of materials for which specific measures may be ad

33、opted, such as (see article 5 of the regulation for the complete list of the “Specific measures for groups of materials and articles“): a. a list of substances authorised for use in the manufacturing; b. purity standards for substances referred to in (1); c. limits on the migration of certain consti

34、tuents; d. global limit of migration, etc. The elements of this list are indicated below in the Table 1.

43、 Printing inks Resolution AP (2005) 2 3) Regulations for plastic materials do not apply to materials or articles comprised of two or more layers, when at least one of these layers contains a material other than plastic. These are based on a positive list principle (monomers and other authorised star

44、ting compounds), which sets global migration limits and, for certain monomers, a specific migration limit or maximum quantity of the residual substance. Draft amendment dated 20/2/2003 already ready. A new regulation is currently being drafted to replace all the directives on plastics: Directive 200

45、2/72/EC and its amendments (2004/1, 2004/19, 2005/79, 2007/19). The regulation will also replace the directive 82/711 and its two amendments, 93/8/EEC and 97/48/EC, as well as the three directives on vinyl chloride monomer: 78/142/EEC, 80/766/EEC and 81/432/EEC (see the chapter on tests methods).

The time of contact between material and food product could not be compared between a pa

48、ckage and a machine. Moreover certain machines process tons of products per hours, so the migration is highly diluted. 4) Future modifications to directive 93/10/EEC should enable compatibility with recycling laws to be attained. The previous directive 83/229/EEC relating to materials and articles m

49、ade from regenerated cellulose film and its modifications (directives 86/388/EEC and 92/15/EEC) have been repealed by directive 93/10/EEC.
