This guiding technical document stipulates the technical requirements for the design and manufacture of compression and tension springs. This guidance technical document is applicable to cylindrical spiral compression springs (including shot peening springs) and tensile springs made of cold-drawn stainless steel wire with circular cross-sections of 1Cr18Ni9, Cr12Mn5Ni4Mo3Ae Group I and d=0.8~6mm, with variable load (except impact load). spring.
