Section 7 Hydraulic systems

7.1 System arrangements

7.1.1 Hydraulic fluids are to be suitable for the intended purpose under all operating service conditions.

7.1.2 Materials used for all parts of hydraulic seals are to be compatible with the working fluid at the appropriate working temperature and pressure.

7.1.3 Over-pressure protection is to be provided on the discharge side of all pumps. Where relief valves are fitted for this purpose they are to be fitted in closed circuit, i.e. arranged to discharge back to the system oil tank.

7.1.4 Provision is to be made for hand operation of the systems in an emergency, unless an acceptable alternative is available.

7.1.5 Where hydraulic securing is applied, the system is to be mechanically lockable in the closed position so that, in the event of hydraulic system failure, the securing arrangement will remain locked.
