19、Introduction 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 specific
20、ally 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 requ
21、irements 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
22、 standards 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 propert
23、ies. 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
24、material 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
25、this 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
26、or 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
27、out 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 specifi
28、es the characteristics and requirements for steel wire and wire products coated with polyethylene (PE).

34、ne (Ethene) which constitutes essentially the only monomer 4 Types of PE coating materials Polyethylene coatings are classified into three types according to their density. Type 1 : low density (0,910 g/cm3to 0,925 g/cm3) Type 2 : medium density (0,926 g/cm3to 0,940 g/cm3) Type 3 : high density (0,9

36、d of application. However the PE coating material shall fulfil the requirements of this standard. The processing of the PE coating material shall be at the manufacturers discretion. 5.1.2 PE organic coating material consistency The manufacturer shall ensure that the organic coating material composit
37、ion and its characteristics remain constant from batch to batch and unchanged from that as agreed at the time of enquiry and order. 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 bee
38、n agreed between the two parties. At the request of the specifier/purchaser the presence of certain elements may be limited. In any case, the compound composition shall be cadmium free. 5.1.3 Density The density at a temperature of 20 C shall satisfy the values specified in Clause 4 of this standard

According to Table 1, the material is category 5, unless otherwise specified at
40、 the time of enquiry and order.
