Overview - ISO 2162-2:1993
ISO 2162-2:1993, "Technical product documentation - Springs - Part 2: Presentation of data for cylindrical helical compression springs," establishes a uniform system for presenting technical data and representing cylindrical helical compression springs in technical product documentation. Its purpose is to standardize the information shown on tender, order and manufacturing drawings so suppliers, purchasers and manufacturers share consistent spring data.
Key topics and technical requirements
- Scope and intent: Defines how to present graphical and design/manufacturing data for cylindrical helical compression springs used in technical product documentation.
- Graphical representation: Requires spring drawings to follow the representation rules in ISO 2162-1 (simplified representation for springs).
- Spring action data: Recommends indicating spring action by a load–deflection chart (load/deflection graph) showing predominant functional requirements and any special conditions.
- Technical data list: Specifies a uniform data list that must include all information necessary for manufacture. Annex A provides an example preprinted data form to be used for enquiries, offers and orders.
- Key parameters (from Table 1): Typical entries include outside/inside/mean coil diameters (De, Di, D), wire diameter (d), number of active/total coils (n, nt), free/solid/test lengths (L0, Lc, Lrl), spring loads at defined lengths (F1, F2,…), spring rate (Rs), modulus values (G, E), torsion stress and stress range, working temperature, cycle frequency and permissible relaxation.
- Spring ends: Types of ends (open, closed, ground, pigtail, bent-to-centre etc.) are defined and must be indicated in accordance with the standard (see Table 2).
- Manufacturing considerations: Notes on tolerances (avoid unnecessarily tight tolerances), minimum inside diameter for rod-guided springs, and maximum outside diameter for cylinder-guided springs to ensure compatibility with mating components.
Applications and users
ISO 2162-2 is practical for:
- Spring manufacturers and production engineers preparing shop drawings and data sheets
- Design and mechanical engineers specifying compression springs in assemblies
- Procurement and tender teams issuing enquiries and orders
- Technical drafters and CAD specialists creating standardized drawings and title blocks
Using ISO 2162-2 improves clarity in specifications, reduces manufacturing errors, speeds quotation and ordering, and ensures consistent interpretation of spring performance data.
