Overview
SIST EN ISO 2162-2:1998 is an international standard developed by CEN that specifies uniform requirements for the presentation of technical data related to cylindrical helical compression springs. This standard is part of the broader ISO 2162 series focused on technical product documentation for springs. Its primary purpose is to harmonize the way data is presented in technical product documentation such as tender or order drawings, ensuring clear communication and consistency among manufacturers, designers, and customers.
This standard covers graphical representation, data lists, and specific parameters essential for the design, manufacturing, and functional evaluation of cylindrical helical compression springs. By standardizing data presentation, EN ISO 2162-2 helps improve product quality, simplifies ordering processes, and facilitates international trade in spring components.
Key Topics
-
Uniform Data Presentation
The standard establishes a consistent system for displaying graphical and numerical technical data for cylindrical helical compression springs, aiding clarity in documentation.
-
Graphical Representation
Spring representations follow the guidelines of ISO 2162-1, ensuring standardized visuals including coil shape, spring ends, and load-deflection charts that depict spring action and key functional characteristics.
-
Technical Data List
A comprehensive list of design and manufacturing parameters is required. This includes details such as:
- Outside and inside diameters of the spring
- Mean coil diameter
- Wire diameter and modulus of elasticity
- Spring load under specified conditions
- Free length, solid length, coil count, and spring rate
- Working temperature and frequency conditions
-
Types of Spring Ends
Specifies standardized forms of spring ends (open, closed, ground, pigtail, bent) identified by letter symbols, important for correct fitting and function.
-
Adaptation and Tolerances
Permits specification of allowable manufacturing deviations to optimize economy without compromising spring performance.
Applications
SIST EN ISO 2162-2:1998 is essential for:
-
Engineering and Design Teams
Designers creating product drawings can use the standard to present spring data effectively, improving design accuracy and communication.
-
Manufacturers
Manufacturers rely on standardized data presentation to interpret orders precisely and produce springs that meet technical and quality requirements.
-
Procurement and Tendering
Standardized data sheets facilitate comparisons of spring offers during procurement, streamlining tender evaluations and order processing.
-
Quality Assurance
Consistent documentation helps verify manufacturing compliance and assists in testing and inspection procedures.
-
International Trade
Harmonized technical documentation simplifies collaboration between global partners and supports regulatory compliance.
