1、BRITISH STANDARD BS EN ISO 14922-2:1999 Thermal spraying Quality requirements of thermally sprayed structures Part 2: Comprehensive quality requirements The European Standard EN ISO 14922-2:1999 has the status of a British Standard ICS 25.220.20BSENISO14922-2:1999 This British Standard, having been
2、prepared under the directionof the Sector Committeefor Materials and Chemicals, was published underthe authority of the Standards Committee and comesinto effect on 15 August 1999 BSI 03-2000 ISBN 0 580 32443 5 National foreword This British Standard is the English language version of EN ISO 14922-2:
3、1999. It is identical with ISO 14922-2:1999. The UK participation in its preparation was entrusted to Technical CommitteeSTI/40, Thermally sprayed inorganic finishes, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee an
4、y enquiries on the interpretation, or proposals for change, and keep the UKinterests 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 agains
5、t EN ISO 14922-2 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 14922-2 achieved the requisite approval from amongst the other European members of CEN, the UK is under an obligation to impl
6、ement 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
7、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 the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all t
8、he 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 legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii

It defines quality requirements for thermal spraying both in workshop
25、s 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 a basis for assessing the manufacturer in respect to his thermal spraying capability. This standard is appropriate when demo
26、nstration of a manufacturers capability to produce thermally sprayed construction, 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
27、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 control of thermal spraying in the following cases: Case 1 To provide specific requirements for thermal spraying in contracts w
28、hich require the manufacturer to have a quality system in accordance with EN ISO 9001 or EN ISO 9002. Case 2 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 3 To provide specific re
29、quirements for thermal spraying in contracts which require 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 how
30、ever be more appropriate for EN ISO 14922-3 or ENISO14922-4 to be used in such cases. 2 Normative references This European standard incorporates by dated or undated reference, provisions from other publications.

This is to ensure that all information necessary to carry out t
37、he 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 adequate planning of all quality related activities. Contract review is carried out by the manufacturer to verify t
38、hat 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 should ensure any variations between the contract and previous tender documentation are identified and the purchase
39、r 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 part of the design review and should be taken into account during the contract review if the design is not carri
40、ed 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 manufacturer is required to take into consideration the requirements of 4.2, whilst carrying out his design review (4.3).
41、 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 specification of thermal spraying procedures, non-destructive testing procedures and heat treatment procedures; c) t
42、he approach to be used for thermal spraying procedure approval; d) the approval of personnel; e) post treatment; f) inspection and testing; g) selection, identification and/or traceability, e.g.for materials, thermal sprayers and coatings (see clause 16); h) quality control arrangements, including a
43、ny 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) environmental conditions relevant to thermal spraying on site; k) sub-contracting; l) handling of non-conformance. 4
44、.3 Application Design review Design requirements to be considered 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 spraye
45、d coatings e) quality and acceptance requirements for coatings; 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)
46、all relevant specifications and requirements shall be supplied by 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 manufa
47、cturer 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 fro
48、m the contract review (see 4.2) and the design review (see 4.3). Additional requirements may need to be specified, if the design of a structure is to be sub-contracted. 6 Personnel for thermal spraying 6.1 General The manufacturer shall have at his disposal sufficient and competent personnel for the
49、 planning, performing, supervising and examining of the thermal spraying production according to specified requirements. 6.2 Qualified thermal sprayer All thermal sprayers shall be approved by a suitable qualification test according to EN ISO 14918. All records of approval shall be maintained up to date.ENISO14922-2:1999 BSI 03-2000 5 6.3 Thermal spraying coordinator The manufacturer shall have at his disposal appropriate thermal spraying coordination personnel such that the t
