AS 2671:2021 pdf download.Hydraulic fluid power -General rules and safety requirements for systems and their components.

5.3.2.4 Installation

Components should be installed so that they are accessible from a safe working position (for example, ground-level or working platform).

5.3.2.5 Use of standard parts

5.3.2.5.1 Commercially available parts (keys, bearings, packings, seals, washers, plugs, fasteners, etc.)

and part configurations (shaft and spline sizes, port sizes, mountings, mounting surfaces or cavities, etc.)

should be selected and coded In accordance with accepted International Standards.

5.3.2.5.2 WIthin a hydraulic system. ports, studs, and connectors should be limited to the minimum number of standard series

possible. All port connections should he in accordance with ISO 6149-1, ISO 6149-2 and ISO 6149-3 for threaded port connections, or ISO 6162-1, ISO 6162-2 or ISO 6164 for four-screw flange port connections.

NOTE When using more than one type of ISO standard threaded port connection [e.g. ISO 1179 (all parts), ISO 9974 (all parts) and

ISO 11926 (all parts)J in a system, there isa strong possibility of incompatible intermixing between some stud ends from one

connection series and some ports from a different connection series, causing leakage and severe failure of the connection system.

Ports and stud ends that conform to ISO 6149-1, ISO 6149-2 and ISO 6149-3 are marked such that they are identifiable.

5.3.2.6 Seals and sealing devices

5.3.2.6.1 Materials

Seal and scaling device materials shall be compatible with the fluid used, adjacent materials and their working conditions and

environment.

5.3.2.6.2 Replacement

Component design shall facilitate servicing and replacement of seals and sealing devices, if such servicing and replacement is

intended.

5.3.3 Cleaning and painting

5.3.3.1 During external cleaning and painting of machinery sensitive materials shall be protected from Incompatible liquids.
