EN ISO 14921:2001

This standard relates to the general procedures of application of thermally sprayed coatings as defined in EN 657.The purpose of these coatings being either to reclaim worn and non conforming parts or to enhance the surfaceproperties of components for specific purposes.For example, to provide wear resistance, low coefficient of friction, electrical or thermal conductivity or insulation,and resistance to corrosion.This standard is not intended to provide definitive methods for specific work and attention shall be paid to the properselection of process and materials for the purpose and to the skills of the thermal sprayer as defined inEN ISO 14918.Additionally it does not include requirements for the protection of structural steelwork, covered by EN 22063, nor theuse of coatings of self fluxing alloys which are subsequently fused, covered by EN ISO 14920.
