TS 7227

TS 7227 is a terminology standard for the classification, designation, and definition of defects associated with flame cutting and plasma cutting. Rather than prescribing how to cut, it establishes a common technical language for the flaws that can appear on cut edges and cut surfaces, supporting clearer inspection records, quality discussions, and engineering communication.

Why these defects are treated as a distinct subject

Flame cutting and plasma cutting are widely used thermal cutting processes in metalworking. Both rely on heat input and material removal, so the resulting edge condition can include features such as dross or slag attachment, roughness, gouges, incomplete separation, distortion, or heat-affected edge conditions. In general technical context, a terminology document matters because similar-looking imperfections may have different causes and different implications for downstream fabrication, even when they are observed on the same part.

What this standard specifically covers

According to the supplied scope, TS 7227 covers defects formed during flame and plasma cutting without any outside stress effect. That boundary is important: the document focuses on defects arising from the cutting operation itself, not on damage introduced later by external loading, handling forces, or other post-cut influences. Its purpose is to classify and define these defects so that production, inspection, and reporting can use consistent terminology.

• Provides shared names for defects associated with flame and plasma cuts.
• Focuses on classification and definition rather than on cutting procedure requirements.
• Covers defects formed without outside stress influence.
• Supports consistent technical communication in inspection and manufacturing contexts.
