A list of organizations represented on this committee can be obtained on request to its secretary. The UK voted against EN IS0 14922-1
6、on the grounds that the subject of that standard is already covered by the EN IS0 9000 series on quality management and quality assurance. However, as EN IS0 14922-1 achieved the requisite approval from amongst the other European members of CEN, the UK is under an obligation to implement it as a Bri

23、667 0792328 184 = Page 4 EN IS0 14922-1:1999 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 a
24、utomotive 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 has a great influence
25、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 IS0 9000 and series for quality management systems for insta
26、nce, 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 aie required standard of quality has been fulfilled. Quality cannot be put into a product b
27、y 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. To use the thermal s
28、prayed 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 choise of material, the production and the succeeding testing procedures. To assure perfect thermal spraying
29、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 using the thermal spra
30、ying 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 influenced by thermal spr
31、aying 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 thenally sprayed structures of the
32、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 management to define the therm
33、al 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 following purposes: a) prov
34、iding interpretation of the requirements in the EN IS0 9000 series of standards, as a guideline for specification and establishment of the pari of the quality system related to control of thermal spraying as a “Special Process“; b) providing guidelines to establish specifications and thermal sprayin
35、g quality requirements, where a quality system according to EN IS0 9001 and EN IS0 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: - in contractual si
36、tuation: specification of thermal spraying requirements for quality systems; - by manufacturers: establishment and maintenance of themal spraying quality requirements; - by committees preparing structural codes or other application standards: specification of thermal spraying requirements: - by inte
37、rested parties, e.g. third parties, customers or manufacturers management: assessment of thermal spraying requirements.
