19、reword This document (EN 15773:2009) has been prepared by Technical Committee CEN/TC 139 “Paints and varnishes”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the late
20、st by December 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all
21、 such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Icel

BS EN 15773:2009EN 15773:2009 (E) 5 Introduction In order to achieve a duplex system which satisfies the many varied aesth
23、etic and performance requirements currently in existence in the marketplace, the following aspects of the supply and application of the systems should be controllable: fabrication and composition of the material (Clause 5); the zinc coating (Clause 6); surface smoothing for coating (Clause 6); envir
24、onmental conditions during storage, transport and application (Clause 6); the pre-treatment of the zinc surface (Clause 7); instructions provided by chemical pre-treatment suppliers (Clause 7), powder manufacturers (Clause 8); the organic coating system (Clause 8); packaging, storage and movement of
25、 finished products (Clause 9); installation (Clause 10); inspection (Clause 11). This European Standard does not incorporate the application of paint coatings according to EN ISO 12944 (parts 1 to 8) 1 when paint systems are specified. This European Standard incorporates the application of coating p
26、owders according to EN 13438 when powder coatings are specified. Table 1 shows the relationship between this European Standard, EN 13438 and other standards relating to zinc coated articles.

28、ements made between galvanizer or sherardizer and client regarding general quality requirements in relation to zinc coating. NOTE prEN ISO 14713-2 and -3 also provide useful information on design for galvanizing and sherardizing respectively. Good communications in place and agreements made between
29、the client and the company applying the powder organic coating regarding general quality requirements of the powder organic coating. Good communications in place and agreements made between client, galvanizer or sherardizer and applicator of the powder organic coating regarding quality requirements
30、for duplex systems in relation to quality of zinc coating, the pre-treatment and powder organic coating. BS EN 15773:2009EN 15773:2009 (E) 6 1 Scope This European Standard specifies the agreements to be made between the client, the galvanizer / sherardizer, the chemical suppliers and the applicators
31、 of the pre-treatment and the powder organic coating systems (if they are not one and the same). It also specifies the quality of the galvanized or sherardized articles to which the powder organic coatings are to be applied and for the pre-treatment and powder organic coatings intended for applicati
32、on to the galvanized or sherardized articles. This standard applies to the application of hot dip galvanized, sherardized and powder organic coatings by controlled industrial processes to articles consisting of or manufactured from steel. The standard applies to hot dip galvanized products, galvaniz
33、ed in accordance with EN ISO 1461 and EN 10240 or products sherardized in accordance with EN 13811, as well as parts of these products manufactured from continuously galvanized sheet and strip galvanized in accordance with EN 10326 or EN 10327, which, after the galvanizing and/or assembly, or sherar
34、dizing, will have a powder organic coating system applied. This standard also applies to products which have been hot dip galvanized or sherardized according to specific product standards to which powder organic systems are applied. This standard might also be useful when supplying other organic coa
35、ting systems (excluding wet paint systems). 2 Normative references The following referenced documents are indispensable for the application of this document.
