The subsequent parts of this standard deal more specifically 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. This standard is made up of the following parts: Part 1: General rules Part 2: PVC coated wire Part 3: PE coated wire Part 4: Polyester coated wire In writing this series of standards consideration has been given to the nomenclature and transformation of organic materials as applied to steel wire. 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 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 tests and testing methods on organic coating 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 following structure has been chosen for this standard. Clause 5 deals with the characteristics and testing methods of organic coating material as supplied by the manufacturer for the purpose of its application to the wire. Tests described in this section are intended to be carried out by the organic coating material manufacturer or the applicator before the 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 “applicator“. Clause 7 defines the Performance requirements and testing methods on the “organic coating“ of the finished wire. When testing on the finished wire is not possible, tests will be carried out on “coated“ panels.

It is the result of a polycondensation reaction of a polyhydroxy compound with di- or polycarbon acids. 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 PET one of the most commonly used linear polyesters is polyethyleneglycoltereftalate denominated by its abbreviation PET NOTEPET 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 wire 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 methods 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 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 manufacturer's discretion. The requirements for the polyester intended for extrusion are those for PET. For 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 ordering. 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 specifier or purchaser the presence of certain elements may be limited. In any case, the compound composition shall be cadmium free. 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 ISO 1183, shall be in accordance with Table 1. Where the apparent density of the supplied powder is specified, requirements and test methods shall be agreed between the parties.

If so agreed between the parties 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 527-3 the elongation shall be in accordance with Table 1.
