Tools for pressing - Compression springs with rectangular section - Housing dimensions and colour coding (ISO 10243:2019, IDT)
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.
