3、0 ISBN 0 580 32442 7 National foreword This British Standard is the English language version of EN ISO 14922-1:1999. It is identical with ISO 14922-1:1999. The UK participation in its preparation was entrusted to Technical Committee STI/40, Thermally sprayed inorganic finishes, which has the respons
4、ibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries 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 lis
5、t of organizations represented on this committee can be obtained on request to its secretary. The UK voted against EN ISO 14922-1 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 14922-1 achi
6、eved the requisite approval from amongst the other European members of CEN, the UK is under an obligation to implement 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
7、publications with their corresponding European publications. The British Standards which implement international or European 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 th
8、e “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary 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
9、 legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN ISO title page, pages 2 to 7 and a back cover.

23、006, Uncontrolled Copy, (c) BSI EN ISO 14922-1:1999 BSI 03-20003 Introduction Thermal spraying processes are widely applied for producing industrial products. Thermal spraying has become increasingly important in parts of industrial application, manufacturing, maintenance and repair. It is applied o
24、n constructions in automotive industry, aerospace gasturbines, machinery construction, printing industry, chemical industry for anticorrosive purposes, antiwear, high temperature protection and against chemical attack, to mention some of the applications. Consequently the thermal spraying process ha
25、s a great influence on the production costs and completion of the product. Therefore it is important to apply the thermal spraying process in an effective way and to carry out quality management and assurance on any point of the production. In the standard EN ISO 9000 and series for quality manageme
26、nt systems for instance, the processes for protecting surfaces are pointed out as special processes, because most of the processes for surface protection cannot be NDT-controlled during the production in that way to garanty that the required standard of quality has been fulfilled. Quality cannot be
27、put into a product by testing afterwards, but it has to be created in it by quality assurance during its manufacturing. Even the most developed and complete nondestructive testing procedures do not improve the quality of a thermal sprayed coating afterwards, they only give records upon its quality.
28、To use the thermal sprayed coating adequatedly and to avoid severe problems during the production and during operational time, controlling and supervising are necessary including the phases of construction, the choice of material, the production and the succeeding testing procedures. To assure perfe
29、ct thermal spraying manufacturing and to recognize sources of possible problems, the manufacturers management has to introduce an adequate quality management. 1 Scope This standard specifies guidelines to describe thermal spraying quality requirements suitable for application by the manufacturers us
30、ing the thermal spraying process for coating new parts, for repair and maintenance. They are structured in the way that they can be used for any type of construction to be sprayed. These guidelines relate only to those aspects of the quality of the final construction to be sprayed which may be influ
31、enced by thermal spraying and allied processes (pre- and posttreatment, etc.). The guidelines define various approaches to quality requirements for thermal spray works, both in workshops and on sites and to provide guidance for describing the capability of a manufacturer on producing thermally spray
32、ed structures of the specified quality. They also can be used by any interested party as a basis for assessing a manufacturers thermal spraying quality arrangements. The guidelines are intended as a guide for the preparation of regulatory or contractual requirements and for a manufacturers managemen
33、t to define the thermal spraying requirements for quality system related to the type of thermally sprayed construction. The guidelines are not structured to be used in isolation as a part of any regulatory contractual or managerial requirement. These guidelines are intended to be used for the follow
34、ing purposes: a) providing interpretation of the requirements in the EN ISO 9000 series of standards, as a guideline for specification and establishment of the part of the quality system related to control of thermal spraying as a “Special Process”; b) providing guidelines to establish specification
35、s and thermal spraying quality requirements, where a quality system according to EN ISO 9001 and EN ISO 9002 is not involved; c) assessment of the thermal spraying quality requirements mentioned in a) and b) above. The application of this standard would typically occur in the following circumstances
36、: in contractual situation: specification of thermal spraying requirements for quality systems; by manufacturers: establishment and maintenance of thermal spraying quality requirements; by committees preparing structural codes or other application standards: specification of thermal spraying require
37、ments; by interested parties, e.g. third parties, customers or manufacturers management: assessment of thermal spraying requirements.

43、ordered by the customer, or manufacturers basic specification for constructions manufactured in series for several customers, unknown to the manufacturer at the time of design and production the contract is, in both cases, assumed to include reference to all relevant regulatory requirements NOTEThe
44、role of an independent body is considered to be a matter which is determined by the contracting parties and/or the application standard. 3.2 special process processes the results of which cannot be fully verified by subsequent inspection and testing of the product and where, for example, processing
45、deficiencies may become apparent only after the product is in use. Accordingly, continuous monitoring and/or compliance with documented procedures is required to ensure that the specified requirements are met (see 4.9 of EN ISO 9001:1994) 3.3 manufacturing organisation organization of which the ther
46、mal spraying workshops and/or sites are under the same technical and quality management 3.4 qualified person (for thermal spraying) a person whose competence and knowledge has been obtained by education, by training and/or relevant practical experience 3.5 construction (for thermal spraying) synonym
47、 for product, structure or any other thermally sprayed system 3.6 quality management system according to ISO 8402 4 Selection of quality requirements for thermal spraying By using this standard it is possible to select the thermal spraying quality requirements, to suit the type of thermally sprayed
48、constructions concerned, in accordance with the following parts as appropriate: Quality requirements of thermally sprayed structures Part 2: Comprehensive quality requirements (EN ISO 14922-2); Quality requirements of thermally sprayed structures Part 3: Standard quality requirements (EN ISO 14922-3
49、); Quality requirements of thermally sprayed structures Part 4: Elementary quality requirements (EN ISO 14922-4). Guidance in the selection is shown in Table 1. Annex A and Annex B also give further information on the selection and content of Part 2, 3 and 4.
