TS EN ISO 9222-2

TS EN ISO 9222-2 sets out rules for the detailed simplified representation of seals used in dynamic applications on technical drawings. Rather than reproducing the full manufacturing geometry of a seal, the standard provides a consistent drawing language that makes the part easier to identify and read across engineering documents. This helps drawings remain clear when the seal appears within assemblies, subassemblies, or system layouts.

Drawing language for dynamic sealing elements

Seals for dynamic applications are components designed to limit fluid leakage along moving shafts, pistons, or similar interfaces. Depending on the application, they may take different forms and seat arrangements. In technical drawing, a simplified representation expresses that variety through standardised conventions and outlines instead of repeating every geometric detail. This is especially useful in assembly drawings, where clarity and drawing economy matter as much as dimensional definition.

What this part focuses on

• The standard covers rules for the detailed representation of various sealing elements.
• Its subject is the simplified depiction of seals intended for dynamic service in technical drawings.
• It supports how these components are shown and read in engineering documentation.
• Its emphasis is on drawing representation and terminology consistency, not on seal performance testing.

In general engineering practice, standards of this kind reduce ambiguity in mechanical drawings and make component identification more consistent. Sealing elements may be small, but they are important to system integrity and assembly fit, so their graphical representation needs to be immediately recognisable and uniformly understood. TS EN ISO 9222-2 is one of the part standards that supports that common visual language.
