17、al spraying and thermally sprayed coatings”, the secretariat of which is held by DIN, in collaboration with Technical Committee ISO/TC 107 “Metallic and other inorganic coatings”. This European Standard shall be given the status of a national standard, either by publication of an identical text or b
18、y endorsement, at the latest by September 2005, and conflicting national standards shall be withdrawn at the latest by September 2005. This document supersedes EN 22063:1993. Annex A and B are informative. Annex ZA is normative. This document includes a Bibliography. According to the CEN/CENELEC Int
19、ernal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Neth
20、erlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom EN ISO 2063:2005 (E) 4Introduction Thermal-sprayed metallic coatings are produced by heating the coating metal to its molten stage and projecting it in a stream of gas onto the prepared surface to be
21、 coated. It is essential that the purchaser specifies the coating metal or alloy and the thickness of the coating required: merely to ask for thermal metal spraying to be carried out in accordance with this standard, without this information, is insufficient. It is essential that the design of the a
22、rticle is such that it may be coated properly. EN ISO 2063:2005 (E) 51 Scope This standard applies to thermal-sprayed metallic coatings for the protection of iron and steel against corrosion by applying zinc or aluminium or their alloys to uncoated surface to be protected. This standard deals with c
23、haracteristic properties and gives test methods for coatings obtained by the spraying of zinc and aluminium and their alloys for the general purpose of corrosion protection. It gives firstly the definition, classification and symbols for these coatings in relation to their thickness. It then deals w
24、ith the preparation of surfaces, application of coatings and their characteristic properties: namely, thickness, appearance and adhesion. Finally it gives test methods for checking these properties. For other metals some of the provisions are valid and can be adopted by agreement between the interes
25、ted parties. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

36、s For the purposes of this European Standard, the terms and definitions given in EN ISO 2064:2000 and the following apply. 3.1significant surface part of the article covered or to be covered by the coating and for which the coating is essential for serviceability and/or appearance 3.2minimum local t
37、hickness lowest value of the local thickness found on the significant surface of a single article 4 Manner of specifying requirements When specifying the coating of articles by thermal spraying in accordance with this standard, the purchaser shall state, in addition to the number of the standard, th
38、e significant surface of the metal coating and its thickness in accordance with the symbols indicated in Table 1. EN ISO 2063:2005 (E) 75 Classification The zinc, aluminium or Zn-Al alloy coatings considered in this standard are classified in a scale according to their thickness, in conformity with
39、the indications in Table 1.
