This European standard defines the requirements to be specified in the coating specification for a thermally sprayed coating. It applies to components and workpieces made of metallic or non-metallic materials that are to be partially or completely coated with thermally sprayed coatings. The coating can be made of metals, metal ceramics, oxide ceramics or plastics. Additional requirements for the coating manufacturer that are not coating-specific are intended to be included by defining the technical supply conditions according to EN ISO 12670. The requirements defined in this standard are intended to be met by a component-related thermal spray procedure specification (TSPS) prepared by the coating manufacturer. The thermal spray procedure specification is intended to be documented and component-related to ensure traceability. For details, see FprEN 17002. Proof that the requirements of the coating specification are met by the application of the thermal spray procedure specification can be provided by performing a component-related procedure qualification according to EN 15648. If specific coating requirements cannot be specified by the customer, they are intended to be agreed with the contractor on the basis of the requirements for the sprayed coating – e.g. against fretting wear at high temperatures – and on the basis of the contractor's past experience.
