Foreword
This document EN ISO 17834:2003 has been prepared by Technical Committee CEN/TC 240 “Thermal 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
by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by
June 2004.
Annex A is informative. Annex B is normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This standard is applicable to sprayed metal coatings for protection against corrosion at temperatures up to 1000°C
(1273 K).
For the protection of iron and steel by sprayed aluminium and zinc coatings against atmospheric corrosion
reference should be made to prEN ISO 2063.
Coating materials other than metals, although they may be applied by spraying, are outside the scope of this
standard.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
