TS EN 14665

TS EN 14665 is a standard concerned with the symbolic representation of thermally sprayed coatings on drawings. The subject is not the spraying process itself, but how such coatings are communicated clearly and consistently in technical documentation. Thermal spraying is a surface engineering family in which molten or semi-molten material is propelled onto a substrate to form a coating, and drawing symbols help engineers, manufacturers, and inspectors describe that coating in a shared technical language.

How symbolic notation supports engineering drawings

In engineering practice, drawing symbols condense process information into a compact form that can be read across design, production, and inspection. For thermal spray coatings, the notation helps distinguish this surface treatment from paint, plating, hardfacing, or other finishing methods that may look similar on a finished part but serve different functions. Clear symbolic representation reduces ambiguity and supports consistent communication about where a coating is intended and how it should be understood in the drawing context.

Why this topic matters in surface engineering

Thermally sprayed coatings are widely used for wear resistance, corrosion control, thermal management, and functional surface performance. In drawings, standardized symbols make it easier to identify coated areas and preserve the designer’s intent during manufacturing and review. This record reflects the technical topic indicated by the title; without an official scope text here, it should be read as general technical background rather than a clause-by-clause summary of the standard’s exact rules, symbols, or mandatory notation.
