Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This third edition cancels and replaces the second edition (ISO 10243:2010), which has been technically revised. It also incorporates the Amendment ISO 10243:2010/Amd 1:2011.

The main changes compared to the previous edition are as follows:

• some values of spring rate have been modified in Table 2 to Table 5;
• a column giving the force at maximum operating deflection has been added in Table 2 to Table 5.

1 Scope

This document establishes the technical specifications for compression springs made from rectangular wires.

The parameters set in this document are applicable to springs which are set. This document does not attempt to specify the quality of the springs themselves, nor all of their dimensions (e.g. cross-section), their material or their length of life.

The springs are classified into spring rates: light, medium, strong and extra strong. For each spring rate, this document gives a colour code.

2 Normative references

There are no normative references in this document.

3 Terms and definitions
