This document specifies two different grades of disc springs. Grade A defines basic requirements of disc springs for static applications with low and moderate performance. Springs manufactured according to Grade A are not used for dynamic applications. Grade B defines requirements on disc springs especially used for dynamic applications and high performance static applications. Disc springs according to Grade B ensure a better quality by higher demands on manufacturing processes and tolerance requirements. Grade B includes graphs showing the guaranteed fatigue life such as a function of stress.

This International Standard specifies the materials, shapes, spring characteristics, tolerances, manufacturing requirements and test methods for common helical compression springs, which are made from hot coiled round section steel bar, and then quenched and tempered (hereinafter simply "springs"). The following limit values apply to springs conforming to this International Standard: — free length: ≤ 900 mm; — spring index: 3 to 12; — slenderness ratio: 0,8 to 4; — active coils: ≥ 3; — spring pitch: D; — wire diameter: 8 mm to 60 mm; — mean diameter of coil: ≤ 460 mm. This International Standard is not applicable to coil springs with special performance requirements, such as railway and automotive suspensions.
