What is ISO 22705‑1 about?
ISO 22705‑1 is the first part in the multi-series of documents that is applicable to springs on measurement and test parameters.
ISO 22705‑1 specifies the measurement and test methods for the general characteristics of cold-formed helical compression springs made from round wire, excluding dynamic testing.
Who is ISO 22705‑1 for?
ISO 22705‑1 on springs is relevant to:
- Manufacturers
- Customers and suppliers
- Mechanical engineers and designers
Why should you use ISO 22705‑1?
ISO 22705‑1 defines spring as a mechanical device designed to store energy when deflected and to return the equivalent amount of energy when released.
ISO 22705‑1 covers measurement and test parameters for technical cold-formed cylindrical compression springs. Specifications for free length, outside and inside diameter, solid length and solid force, spring load and spring pitch, are provided in ISO 22705‑1.
The calculation method and formula to determine the spring rate is also provided. This helps assess how much load you will be required to place on your spring in order to travel 1 inch of deflection. Through the assessment of the spring rate, you can determine the right level of softness of stiffness required for your applications.
