This standard specifies the technical requirements, test methods, inspection rules, marking and packaging of marine hydraulic hinges. This standard applies to hydraulic hinges that use mineral-based hydraulic oil as the working medium. Their structure is a hydraulic hinge that combines the reciprocating linear motion of the hydraulic cylinder piston and the single-stage spiral motion to output a rotary motion.
