5、 voted against EN IS0 14922-2 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 14922-2 achieved the requisite approval from amongst the other European members of CEN, the UK is under an oblig
6、ation to implement it as a British Standard. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards nody include an annex which lists normative references to international publications with their corresponding European publications.

23、coatings“, the secretariat of which is held by DIN, in collaboration with Technical Committee ISOTTC 107 “Metallic and other inorganic coatings“.

24、cember 1999, and conflicting national standards shall be withdrawn at the latest by December 1999. According to the CEWCENELEC Internai Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmar

26、ThT - Page 4 EN IS0 14922-21 999 1 scope This standard specifies requirements so that: - It is independent 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 capab
27、ility to produce thermally sprayed constructions to meet specified requirements. - It may also be used as 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 c
28、onstruction, fulfilling specified quality requirements, are specified in one or more of the following: - a 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
29、 the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control 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 qualtty system in acco
30、rdance with EN IS0 9001 or EN IS0 9002. - Case 2 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 9002. - Case 3 To provide specific requirements for thermal spraying in contracts which require
31、 the manufacturer developing a quality system. - Case 4 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. It may however be more appropriate for EN IS0 14922-3 or EN IS0 14
32、922-4 to be used in such cases. 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, su

39、ta for construction designed by the manufacturer. This is to ensure that all information necessary to carry out the fabrication operations is available prior to the commencement of the work. The manufacturer shall affirm his capability to meet all thermal spraying contract requirements and ensure ad
40、equate planning of all quality related activities. Contract review is carried out by the manufacturer to verify that the contract is within his capability to perform, that sufficient resources are available to achieve delivery schedules and documentation is clear and unambiguous. The manufacturer sh
41、ould ensure any variations between the contract and previous tender documentation are identified and the purchaser notified of any programme, cost or engineering changes that may result. The items in 4.2 are typically considered at or before time of the contract review. The items in 4.3 usually form
42、 pari of the design review and should be taken into account during the contract review if the design is not carried out by the manufacturer. It shall be ensured that all relevant information has been supplied by the purchaser. When a contract does not exist or items were made for stock, the manufact
43、urer is required to take into consideration the requirements of 4.2, whilst carrying out his design review (4.3). 4.2 Application - Contract review Contractual requirements to be considered should include: a) the application standard to be used, together with any supplementary requirements; b) the s
44、pecification of thermal spraying procedures, non-destructive testing procedures and heat treatment procedures; c) the approach to be used for thermal spraying procedure approval; d) the approval of personnel: e) post treatment; 1) inspection and testing; g) selection, identification andlor traceabil
45、ity, e.g. for materials, thermal sprayers and coatings (see clause 16); h) quality control arrangements, including any involvement of an independent inspection body; i) other thermal spraying requirements, e.g. batch testing of consumables; grain size, distribution and morphology and composition; j)
46、 environmental conditions relevant to thermal spraying on site; k) sub-contracting; I) handling of non-conformance. COPYRIGHT European Committee for StandardizationLicensed by Information Handling ServicesPage 6 EN IS0 14922-2: 1999 4.3 Application - Design review Design requirements to be considere
47、d should include: a) location, accessibility and sequence of all coatings; b) surface finish of the coating; c) substrate material specification and coating properties; d) dimensions and details of prepared substrate surfaces and sprayed coatings e) quality and acceptance requirements for coatings:
48、f) other special requirements, e.g. acceptability of shotpeening, heat treatment, cooling, masking. 5 Sub-contracting When a manufacturer intends to use sub-contracted services (e.g. inspection, non-destructive testing, post treatment) all relevant specifications and requirements shall be supplied b
49、y the manufacturer to the sub-contractor. The subcontractor shall provide such records and documentation of his work as may be specified by the manufacturer. Any sub-contractor shall work under the order and responsibility of the manufacturer and shall fully comply with the relevant requirements of this standard. The manufacturer has to ensure that the sub-contractor can comply with the quality requirements of the contract. The information to be provided by the manufacturer to the sub-contractor shall include all relevant data from the contract review (see 4.2) and the design revi
