ISO 14922-4:1999

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 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 demonstration 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 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.
