The U. S. Technical Advisory Group (TAG) to ISO/TC 131- fluid power systems has been working on a number of projects in May. Following is a sampling of current projects underway in the committees:
Published Standards ISO 3723:2015 — Hydraulic fluid power — Filter elements — Method for end load test – In hydraulic fluid power systems, power is transmitted and controlled through a fluid under pressure within an enclosed circuit. Filters maintain fluid cleanliness by removing insoluble contaminants. The filter element is the porous device which performs the actual process of filtration.
New Work Item Proposal to Revise ISO 6162-2 — Hydraulic fluid power — Flange connections with split or one-piece flange clamps and metric or inch screws — Part 2: Flange connectors, ports and mounting surfaces for use at a pressure of 42 MPa (420 bar), DN 13 to DN 76. This part of ISO 6162 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to four-screw, split and one-piece flange clamp type tube connectors and hose fittings for use at a pressure of 42 MPa (420 bar). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals.
This part of ISO 6162 also recognizes the need to accommodate metric screw fasteners (type 1) (for DN 13 to DN 76), as well as to provide a means to use existing inch screw fasteners (type 2) (for DN 13 to DN 51).
Systematic Reviews — Every five years ISO Standards are reviewed by their technical subcommittees to ensure that they are current. Over the next several months the U.S. TAG to SC 4, SC 5, SC 6 SC 7 and SC 8 will be reviewing a number of ISO Standards for 2015. The individual Standard is either approved for another five years, recommended for a revision or withdrawn.
It is important for the fluid power industry to provide end users with a set of requirements, specifications and guidelines that can be used consistently to ensure that materials, products, processes and services are being used for the purpose they were made. Projects like those listed above are good examples of the work being done by the fluid power technical experts.
