TS 1798

TS 1798 is a standard on how springs are represented in technical drawings. Because springs are functional machine elements that provide force, return motion, or compliance, their correct drawing representation matters for clarity and consistent interpretation. The standard gives rules for depicting springs in a structured way, with examples to guide technical communication.

Why spring representation matters in drawings

In general technical-drawing practice, springs are not always drawn in full geometric detail. Simplified representations are often used so that the drawing remains readable while still conveying the spring’s type, position, and functional role. This is especially useful in assembly drawings, where the interaction between moving parts and elastic elements must be understood quickly and unambiguously.

The scope of this standard is the representation of springs in technical drawings, so its value lies in drawing consistency rather than in design calculation or manufacturing instruction. Its reference to ISO 2162:1973 shows alignment with established international practice for graphical documentation. The subject is the visual language of springs in engineering drawings, not the physical performance limits or detailed engineering design of a specific spring product.

• Standardised visual representation of springs in technical documentation
• Improved readability and consistent interpretation of mechanical drawings
• Reduced drawing complexity without losing the spring’s functional meaning
• Clearer communication of component relationships in assemblies
