ISO 14922-3:1999

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 other than EN ISO 9001 or EN ISO 9002.

• Case 2

To provide specific requirements for thermal spraying in contracts which require the manufacturer developing a quality system.

• Case 3

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 howeverbe more appropriate for EN ISO 14922-4 to be used in such cases.
