7、 This standard differs from DIN EN 13438:2006-01 und DIN EN 13438 Corrigendum 1:2007-12 as follows: a) the term “test sample” has been deleted; b) a new term “substrate” has been introduced; c) Clause 4 includes references to EN ISO 14713-2 and EN ISO 14713-3 to optimise the design of articles to be
8、 processed in accordance with this standard; d) tolerance limits on gloss requirements have been tightened slightly for gloss levels over 50 units (reduced from 10 units to 7 units) and “Table 1 Gloss requirements” has been deleted; e) Clause 6 has been edited to clarify references to “cleaning” as
9、distinct from “preparation” or “pretreatment”; f) reference to (old) Table 1 in Subclause 6.5.5 “Gloss” has been deleted; g) an adhesion test on the finished powder coated article is no longer mandatory (see revised Sub-clause 6.5.6) and should be specified, if required; h) a new “Table 1 Summary of
10、 tests” has been included in Clause 7 for ease of reference; i) the minimum thickness of coated test panels used for tests for mechanical properties has been increased from 0,3 mm to 1,0 mm (see A.3.1); j) references to updated standards have been included, e.g. replacement of ISO 7724-3 with EN ISO
11、 11664-4 (see A.4.2) and replacement of ISO 1518 with EN ISO 1518-1 (see A.4.5); k) Annex B has been modified to clarify references to “cleaning” and “pretreatment” and the content reduced; l) the possibility of an adhesion test on finished articles is now included in Annex D (see D.3.5); m) the con
12、tent of Annex E has been reduced for further information, reference has been made to EN 15773; n) the standard has been editorially revised.

DIN EN 13438:2013-12 EN 13438:2013 (E) 5 Introduction This European Standard has been produced as a result of the growing demand for products made of
38、 powder coated hot dip galvanised or sherardised steel. These products offer a combination of corrosion resistance and decorative appearance. It is assumed in the drafting of this standard that the specified test methods will be applied by those who are suitably trained and supervised. This European
39、 Standard has been written from a coating performance perspective and does not seek to set out one method of powder coating hot dip galvanised or sherardised steel products. Nevertheless, in order to facilitate production of the best quality powder coated hot dip galvanised or sherardised articles,
40、experience has shown how important it is that sufficient dialogue between the client, specifier, designer, fabricator, galvaniser or sherardiser and powder coating applicator takes place at the earliest stages of the project and that, where possible, timescales set out for processing of the work are
41、 practical and adhered to. It is strongly recommended that the guidance document for supply of duplex coatings, EN 15773, Industrial application of powder organic coatings to hot dip galvanized or sherardized steel articles duplex systems Specifications, recommendations and guidelines, is used in co
42、mbination with this standard when specifying for duplex systems. DIN EN 13438:2013-12 EN 13438:2013 (E) 6 1 Scope This European Standard specifies performance requirements for organic coating powders and powder organic coatings as applied to finished articles (hot dip galvanised or sherardised steel
43、 products) for construction purposes. Hot dip galvanised steel products can be articles that have been batch hot dip galvanised (hot dip galvanised after fabrication) or articles consisting of continuously hot dip galvanised sheet which is then subsequently fabricated. This European Standard does no
44、t set out any performance requirements for the powder coating process itself. Guidance on cleaning and pretreatment of the hot dip galvanised or sherardised steel products prior to powder coating is provided. This European Standard does not apply to articles with zinc-aluminium coatings or aluminium
45、-zinc coatings, or to continuously hot dip galvanised wire. This standard does not apply to organic coating powders and powder organic coatings as applied to hot dip galvanised or sherardised steel products (i.e. duplex coated articles) for which there are specific standards, which might include add
46、itional requirements or requirements which are different from those of this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
