TS 7227 EN 12584

TS 7227 EN 12584 defines the terminology used for imperfections that can appear in oxyfuel flame cuts, laser beam cuts and plasma cuts. As a terminology standard, it focuses on naming and grouping the defects found on cut edges and cut surfaces, rather than prescribing how the cutting process itself shall be performed.

Why a common defect vocabulary matters

Oxyfuel, laser and plasma cutting rely on different physical principles, so the appearance, origin and practical significance of imperfections can vary from one process to another. A shared vocabulary helps engineers, inspectors and technical writers describe features such as dross, edge roughness, bevel-like deviation, melting-related irregularities or other cut-surface discontinuities in a consistent way. In this standard, the scope is the collected and grouped terms for possible imperfections; it is not a product acceptance standard.

General technical context for the cutting processes

Oxyfuel cutting removes material by oxidation, especially on carbon steels. Laser cutting uses concentrated beam energy to melt or vaporize material locally. Plasma cutting employs an ionized gas jet and is widely used on electrically conductive materials. Grouping the associated imperfections under one terminology framework reduces ambiguity when the same visual feature is discussed across different cutting methods and supports clearer specification, inspection and documentation practices.

• The standard is centered on terms and definitions.
• It groups possible imperfections for oxyfuel, laser and plasma cutting.
• It does not establish acceptance limits, test methods or repair rules from the title/scope supplied here.
• It functions as a shared technical vocabulary for manufacturing and inspection communication.
