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 manufacturer's 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 demonstration of a manufacturer's 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 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 which 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 requirements 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 however be more appropriate for EN ISO 14922-3 or EN ISO 14922-4 to be used in such cases.
