TS EN ISO 9222-1

TS EN ISO 9222-1 addresses the general simplified representation of seals for dynamic applications in technical drawings. In practice, this means a common drawing language for showing sealing elements without always drafting their full geometric detail, so engineering documents remain readable and consistent across teams and projects.

What the simplified representation is meant to do

In technical drawing, seals are functional components that help prevent fluid leakage between parts that move relative to one another. Dynamic applications typically involve shafts, pistons, or similar moving interfaces. This standard covers the general rules for representing such sealing elements in a simplified way; it is about how they are shown on drawings, not about designing the seal itself or specifying its performance.

Why dynamic seals are shown differently

Dynamic and static seals belong to the same broad family, but they are not presented in the same way in drawings because motion changes the engineering context. Dynamic seals are associated with friction, wear, and the direction of movement, so the drawing needs to communicate placement and functional arrangement clearly. A simplified representation reduces drawing clutter while preserving the essential technical message and supporting a shared vocabulary across disciplines.

• The standard covers general simplified rules for representing seals.
• Its focus is drawing notation and presentation, not seal design calculations.
• Dynamic applications refer to interfaces with relative motion between parts.
• The benefit is clearer, more consistent technical documentation.
