BS EN 15800:2008 Cylindrical helical springs made of round wire. Quality specifications for cold coiled compression springs

BS EN 15800 applies to cylindrical helical compression springs made of round spring wire. Cold coiled compression springs can be made with wire up to about 16 mm diameter. (See also BS EN 13906-1). A specification for the parameters of cold formed helical compression springs is given in the standard.
