1、BRITISH STANDARD BS EN ISO 14922-1:1999 Thermal spraying Quality requirements of thermally sprayed structures Part 1: Guidance for selection and use The European Standard EN ISO 14922-1:1999 has the status of a British Standard ICS 25.220.20BSENISO14922-1:1999 This British Standard, having been prep
2、ared under the directionof the Sector Committeefor Materials and Chemicals, was published underthe authority of the Standards Committee and comesinto effect on 15August1999 BSI 03-2000 ISBN 0 580 32442 7 National foreword This British Standard is the English language version of EN ISO 14922-1:1999.
3、It is identical with ISO14922-1:1999. 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 enqu
4、iries 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
5、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 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 Eu

21、SI 03-2000 3 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 on constructions in automotive industry, aerospace ga
22、sturbines, 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 has a great influence on the production costs and comp
23、letion 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 ISO9000 and series for quality management systems for instance, the processes for protecting
24、 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 put into a product by testing afterwards, but it has
25、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. To use the thermal sprayed coating adequatedly and to
26、 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 perfect thermal spraying manufacturing and to recognize so
27、urces 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 using the thermal spraying process for coating new part
28、s, 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 influenced by thermal spraying and allied processes (pre-
29、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 sprayed structures of the specified quality. They also can
30、 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 management to define the thermal spraying requirements for qua
31、lity 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 following purposes: a) providing interpretation of the requ
32、irements in the EN ISO9000 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 specifications and thermal spraying quality requirements, where a q
33、uality system according to ENISO9001 and ENISO9002 is not involved; c) assessment of the thermal spraying quality requirements mentioned ina) andb) above. The application of this standard would typically occur in the following circumstances: in contractual situation: specification of thermal sprayin
34、g 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 requirements; by interested parties, e.g. third parties, customers
35、or manufacturers management: assessment of thermal spraying requirements.ENISO14922-1:1999 4 BSI 03-2000 2 Normative references This European standard incorporates by dated or undated reference, provisions from other publications.

40、itions shall apply: 3.1 contract (for thermal spraying) agreed requirements for constructions to be sprayed or for the coating ordered by the customer, or manufacturers basic specification for constructions manufactured in series for several customers, unknown to the manufacturer at the time of desi
41、gn and production the contract is, in both cases, assumed to include reference to all relevant regulatory requirements NOTEThe 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 re
42、sults of which cannot be fully verified by subsequent inspection and testing of the product and where, for example, processing 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
43、 the specified requirements are met (see4.9 of ENISO9001:1994) 3.3 manufacturing organisation organization of which the thermal 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
44、been obtained by education, by training and/or relevant practical experience 3.5 construction (for thermal spraying) synonym 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 us
45、ing this standard it is possible to select the thermal spraying quality requirements, to suit the type of thermally sprayed constructions concerned, in accordance with the following parts as appropriate: Quality requirements of thermally sprayed structures Part 2: Comprehensive quality requirements
46、(EN ISO 14922-2); Quality requirements of thermally sprayed structures Part 3: Standard quality requirements (EN ISO 14922-3); Quality requirements of thermally sprayed structures Part 4: Elementary quality requirements (EN ISO 14922-4). Guidance in the selection is shown inTable 1. Annex A andAnnex
47、 B also give further information on the selection and content of Part2,3 and4.ENISO14922-1:1999 BSI 03-2000 5 5 Requirements for quality assurance systems Control and testing are means to avoid the on site application of constructions of insufficient quality. The establishment of a quality assurance
48、 system isone precondition to have a productive manufacturing, assure the right in time completion of components or constructions without unforseen time delays, repairs or other additional measures. The installation of an effective quality assurance system is initially expensive, but in the future i
49、t guarantees high quality to a reasonable cost. Generally, a manufacturer installs one quality system and chooses contracts and constructions, that correspond to his quality assurance system. Suitable standards are listed in clause4 that are the basis for the installation and definition of a quality assurance system for thermal spraying. These standards can be helping means to facilitate the technological development. Table 1 Selection of thermal spraying quality requirement Contract thermal spraying r
