1、BRITISH STANDARD BS EN ISO 14922-4:1999 Thermal spraying Quality requirements of thermally sprayed structures Part 4: Elementary quality requirements The European Standard EN ISO 14922-4:1999 has the status of a British Standard ICS 25.220.20BSENISO14922-4:1999 This British Standard, having been pre
2、pared under the directionof the Sector Committeefor Materials and Chemicals, waspublished underthe authorityof the Standards Committee and comesinto effecton 15August1999 BSI 03-2000 ISBN 0 580 32445 1 National foreword This British Standard is the English language version of EN ISO 14922-4:1999. It
3、 is identical with ISO 14922-4:1999. The UK participation in its preparation was entrusted to Technical Committee STI/40, Thermally sprayed inorganic finishes, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enqui
4、ries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international 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 I
5、SO 14922-4 on the grounds that the subject of that standard is already covered by the EN ISO 9000 series on quality management and quality assurance. However, as EN ISO 14922-4 achieved the requisite approval from amongst the other European members of CEN, the UK is under an obligation to implement
6、it as a British Standard. Cross-references 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 Eur
7、opean publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the nec
8、essary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, theE

23、pendent of the type of the thermally sprayed structure. It defines quality requirements for thermal spraying both in workshops and on site. It provides guidance for describing a manufacturers capability to produce thermally sprayed constructions to meet specified requirements. It may also be used as
24、 a basis for assessing the manufacturer in respect to his thermal spraying capability. This standard is appropriate when demonstration of a manufacturers capability to produce thermally sprayed construction, fulfilling specified quality requirements, are specified in one or more of the following: a
25、contract between involved parties; 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 applicable to the construction concerned. They provide a flexible framework for the co
26、ntrol of thermal spraying in the following cases: Case 1 To provide specific requirements for thermal spraying in contracts which require the manufacturer to have a quality system other than EN ISO 9001 or EN ISO 9002. Case 2 To provide specific requirements for thermal spraying in contracts which r
27、equire the manufacturer developing a quality system. Case 3 To provide specific requirements for thermal spraying in application standards which uses thermal spraying as part of its requirements or in a contract between relevant parties. 2 Normative references This European standard incorporates by
