TS 1798-1 EN ISO 2162-1

TS 1798-1 EN ISO 2162-1 is a technical product documentation standard that sets rules for the simplified representation of springs on technical drawings. It addresses how compression, extension, torsion, disc, helical and leaf springs are shown in a reduced, readable form so that drawings remain clear without repeating the full geometric detail of the component.

Why simplified representation matters in technical drawings

Springs are mechanical elements that store energy, apply force and help return a mechanism to position. In drawing practice, their full geometry can be visually dense and may obscure the overall design. Simplified representation uses standardized drawing conventions to indicate the spring type, placement and essential form. In general technical documentation, this improves readability and helps designers, manufacturers and inspectors interpret the same drawing consistently.

Spring types covered by the standard

• Compression springs: springs that work under axial compression
• Extension springs: springs that generate force when stretched
• Torsion springs: springs that develop torque against rotation
• Disc springs: compact springs used for axial force applications
• Helical springs: springs with a coiled form
• Leaf springs: flat elastic members that act as springs

In broader engineering documentation, such conventions reduce repetition while preserving the information needed to identify the component. The standard provides rules for simplified drawing representation; it does not define a specific spring design, sizing method or performance calculation. Its value lies in a common visual language for spring depiction in technical drawings.
