ISO 14921:2010规定了热喷涂涂层用于增强部件表面性能或回收磨损和不合格零件的一般程序。 由于技术、物理和/或化学要求以及部件形状的多样性，ISO 14921:2010未提供具体工作的确定方法。 ISO 14921:2010规定了为此目的选择喷涂程序和材料的一般条件。ISO 14921:2010不适用于ISO 2063适用的用于保护钢结构免受大气腐蚀的热喷涂锌和/或铝涂层。 ISO 14921:2010也不适用于随后熔化的自熔合金涂层。ISO 14920涵盖了该程序。

ISO 14921:2010 specifies the general procedure, when a thermally sprayed coating is applied to enhance the surface properties of a component or to reclaim worn and non-conforming parts. ISO 14921:2010 does not provide definitive methods for specific work due to the variety of the technological, physical and/or chemical requirements and of the component's shape. ISO 14921:2010 specifies the general conditions for the selection of the spraying procedure and materials for this purpose. ISO 14921:2010 does not apply to thermally sprayed zinc and/or aluminium coatings for protection of steel structures against atmospheric corrosion, for which ISO 2063 applies. ISO 14921:2010 also does not apply to coatings of self-fluxing alloys which are subsequently fused. That procedure is covered by ISO 14920.
