4、4 1999. The UK participation in its preparation was entrusted to Technical Comnuttee SW40, Thermally sprayed inorganic finishes, which has the responsibjlity to: - aid enquirers to understand the text; - present to the responsible internationavEuropean committee any enquiries on the interpretation,
5、or proposals for change, and keep the UK interests informed - monitor related intemational and European developments and promulgate them in the UK A list of organizations represented on this committee can be obtained on request to its secretary. The UK voted against EN IS0 14922-4 on the grounds tha
6、t the subject of that standard is already covered by the EN IS0 9000 series on quahty management and quality assurance. However, as EN IS0 149224 achieved the requite approval from amongst the other European members of CEN, the UK is under an obligation to implement it as a British Standard. Cross-r
7、eferences Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in

CEN members are bound to
13、comply with the CEWCENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central
14、Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the
15、official versions. CEN members are the national standards bodies of Austria, Belgium, Czech Republic. Denma - an application standard; - a regulatory requirement. The requirements contained within this standard may be adopted in full or may be selectively deleted by the manufacturer if not applicabl
16、e to the construction concerned. They provide a flexible framework for the control of thermal spraying in the foliowing cases: - Case 1 To provide specific requirements for thermal spraying in contracts which require the manufacturer to have a quality system other than EN IS0 9001 or EN IS0 92. - Ca
17、se 2 To provide specific requirements for thermal spraying in contracts which require the manufacturer developing a quality system. - Case 3 To provide specific requirements for themal spraying in application standards which uses thermal spraying as part of its requirements or in a contract between
18、relevant parties. 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 amend
