18、roduction This European 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 specificall
19、y with clearly defined coatings 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 require
20、ments and tests not only 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 st
21、andards consideration has 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
22、. This standard specifies 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 mat
23、erial, which have become 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 th
24、is standard: Clause 4 deals 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
25、 the applicator before the coating operation. Clause 5 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 ou
26、t by the coating “applicators”. Clause 6 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. 1 Scope Complementary to EN 10245-1, this European Standard specifies
27、 the characteristics and requirements for steel wire and wire products coated with Polyamide (PA6).

34、polyamide coating PA6a coating on wire and wire products made from organic coating material consisting primarily of polyamide (PA6) obtained by various polymerisation process NOTE The coating material may also contain plasticizers, pigments, stabilisers, lubricants and other substances. The coating
35、material is in the form of powder or granules. BS EN 10245-5:2011EN 10245-5:2011 (E) 6 4 Methods of application and classes of Polyamide (PA6) coatings The organic coating material shall be applied from granules by extrusion or from powders by the fluidised bed method or powder spraying. Polyamide (
36、PA6) coatings are classified on the basis of their method of application: either by extrusion or by fluidised bed or powder spraying and on the basis of their degree of adherence to the base wire. Class 1a: Wire with a Polyamide (PA6) coating applied by direct extrusion onto the base wire. Class 1b:
37、 Wire with Polyamide (PA6) coating applied by extrusion and made to adhere to the base wire by the use of a primer which may be thermally cured or by the use of organic glues. Class 2a: Polyamide (PA6) powder material applied by thermal fusion or electrostatic spray directly on the base wire. Class
38、2b: Wire that has been pretreated with a primer, thermally cured and then covered with a Polyamide (PA6) powder applied thermally or electrostatically. 5 Requirements and testing methods for the Polyamide (PA6) coating material 5.1 Requirements 5.1.1 General The requirements for the coating material
39、 are summarized in Table 1. 5.1.2 The Polyamide (PA6) organic coating composition The composition shall be agreed between manufacturer and the applicator and shall take account of the latters method of application. However the Polyamide (PA6) organic coating material shall fulfil the requirements of
40、 this standard. The processing of the Polyamide (PA6) coating material shall be at the manufacturers discretion. 5.1.3 Polyamide (PA6) organic coating material consistency The manufacturer shall ensure that the organic coating material composition and its characteristics remain constant from batch t
41、o batch and unchanged from that as agreed at the time of ordering. The processing of the Polyamide (PA6) coating material shall be at the manufacturers discretion. The manufacturer shall immediately notify the applicator of any subsequent change in the type and quantity of the constituent parts of t
42、he composition once this has been agreed between the two parties. At the request of the supplier/purchaser the presence of certain elements may be limited. In any case, the compound shall be cadmium free. BS EN 10245-5:2011EN 10245-5:2011 (E) 7 5.2 Test methods The tests shall be performed in accord
