DIN EN 10245-4:2012-01 EN 10245-4:2011 (E) 4 Introduction This European
20、Standard for organic coatings for steel wire covers the requirements of a general nature and applies also to coatings for which no specific requirements have been established in the subsequent parts of this standard. The subsequent parts of this standard deal more specifically with clearly defined c
21、oatings or groups of coatings. These coatings may have their own particular methods of application and their individual requirements which are specified in these parts of this standard, in other standards or in manufacturers data sheets. Because the standard specifies requirements and tests not only
22、 for the coating but also for the coating material, it has proved not practical to put all the requirements in one clause and all the tests in another one. Following structure has been chosen in order to limit complexity and to facilitate the use. In writing this series of standards consideration ha
23、s been given to the nomenclature and transformation of organic coating materials as applied to steel wire products. These organic coating materials may, on application to wire and by their integration into the finished wire product, change their characteristics and properties. This standard specifie
24、s characteristics and tests not only for the organic coating but also for the coating materials both before and after their application to steel wire and wire products. In addition it specifies the requirements for performance levels and testing methods on organic coating material which have become
25、an integral and permanent part of the finished wire product. Therefore it has proven not to be practical to put all requirements in one clause and all the tests in another one. To aid continuity and in order to limit complexity, the following structure has been chosen for this standard: Clause 5 dea
26、ls with the characteristics and testing methods of organic coating material as supplied by the manufacturer for the purposes of its application to the wire product. Tests described in this section are intended to be carried out by the organic coating material manufacturer or the applicator before th
27、e coating operation. Clause 6 relates to the characteristics and testing methods for the “organic coating“ when the organic coating material has been applied to and has become an integral part of the finished wire. Consequently tests are intended to be in the main carried out by the coating “applica
28、tors“. Clause 7 defines the performance requirements and testing methods on the “organic coating“ of the finished wire product, and where this is not possible, tests will be carried out on “coated“ panels Scope 1 Scope Complementary to EN 10245-1, this European Standard specifies the characteristics
29、 and requirements for steel wire and wire products coated with polyester. It covers both thermoplastic and thermosetting polyester.

38、ids NOTE There are two main classes of polyester: the linear polyesters and the crosslinked polyesters. Linear polyesters generally are thermoplastic, whereas crosslinked polyester is thermosetting and is hard. 3.2 polyethyleneglycoltereftalate (PET) one of the most commonly used linear polyesters N
39、OTE PET is only the abbreviation of polyethyleneglycoltereftalate. The designation of other types of polyester by PET is not correct and is to be avoided. 4 Methods of application of polyester coatings The most commonly used method for polyester coating on wire is by extrusion and for coating of wir
40、e products is by powder coating. The coating may be applied directly on the surface of the wire or wire product or after applying a primer. Where appropriate other methods may be used. 5 Requirements and testing methods for polyester coating material 5.1 General Unless otherwise specified the test m
41、ethods for polyester coating material shall be in accordance with EN 10245-1. 5.2 Composition and method of application The coating material shall be free of lead (Pb), cadmium (Cd) and benzoin. Other requirements for the composition shall be agreed between manufacturer and applicator and shall take
42、 account of this method of application. However, the polyester coating material shall fulfil the requirements of this standard. The processing of the polyester coating material shall be at the manufacturers discretion. The requirements for the polyester intended for extrusion are those for PET. For
43、other coating material other requirements may be agreed between the parties. 5.3 Consistency The manufacturer shall ensure that the organic coating material composition and its characteristics shall remain constant from batch to batch and unchanged from that as agreed at the time of inquiry and orde
44、ring. The manufacturer shall immediately notify the applicator of any subsequent change in the type and quantity of the constituent parts of the composition once this has been agreed between the two parties. At the request of the supplier or purchaser the presence of certain elements may be limited.
45、 In any case, the compound composition shall be cadmium-free. DIN EN 10245-4:2012-01 EN 10245-4:2011 (E) 7 5.4 Density Unless otherwise agreed between the applicator and the coating material supplier the density of the coating material, when tested in accordance with EN ISO 1183- 1 to -3, shall be i
46、n accordance with Table 1. Where the apparent density of the supplied powder is specified, requirements and test methods shall be agreed between the parties. 5.5 Hardness When measured in accordance with EN ISO 868 the Shore hardness D shall be in accordance with Table 1. If so agreed between the pa
47、rties the Bucholtz hardness, when measured in accordance with EN ISO 2815, shall be in accordance with Table 1. 5.6 Tensile strength When tested in accordance with EN ISO 527-3 the minimum tensile strength shall be in accordance with Table 1. 5.7 Elongation When tested in accordance with EN ISO 527-
48、3 the elongation shall be in accordance with Table 1.
