Scope
This document specifies the technical requirements for cylindrical coil springs used in diesel engine fuel injection pumps, speed regulators, and injectors, and describes the corresponding test methods and inspection rules.
This document applies to cold-formed cylindrical coil springs with a round cross-section, such as the piston springs and oil outlet valve springs used in diesel engine fuel injection pumps, speed regulator springs, and injection pressure regulating springs, as well as springs used in electronic common rail systems. Other non-round cross-sectional cold-formed cylindrical coil springs can be used as a reference.
