TS 1798-2 EN ISO 2162-2

TS 1798-2 EN ISO 2162-2 is a standard for the presentation of cylindrical helical compression springs in technical product documentation, with an emphasis on how the relevant technical data are shown. It provides a common way to represent spring information so that tender and order drawings can communicate the same design intent more consistently.

Why the representation of compression springs matters

Cylindrical helical compression springs are axial-load springs that store energy when compressed. In general engineering practice, their documentation needs to make key properties easy to read and compare, such as free length, wire diameter, outside diameter, active coil count, and the spring’s basic force-deflection behavior. The value of a uniform presentation system is that designers, suppliers, and manufacturers can interpret the same spring data in the same way.

According to the scope, this standard covers the presentation of data and the representation of cylindrical helical compression springs for technical product documentation. In other words, it addresses how these springs are described on drawings and related documents, rather than defining the springs themselves as products.

Value in product documentation workflows

• Helps keep spring geometry and essential dimensions consistent across drawings.
• Reduces ambiguity between tender documents, order documents, and manufacturing records.
• Supports clear distinction between compression springs and other spring types such as extension or torsion springs.
• Improves communication by standardizing how spring data are presented in technical product documentation.
