The U. S. Technical Advisory Group (TAG) to ISO/TC 131- fluid power systems has been working on a number of projects in April. Following is a sampling of current projects underway in the committees:
Published Standards ISO 6953-1:2015 — Pneumatic fluid power — Compressed air pressure regulators and filter-regulators — Part 1: Main characteristics to be included in literature from suppliers and product-marking requirements and ISO 6953-2:2015 — Pneumatic fluid power — Compressed air pressure regulators and filter-regulators — Part 2: Test methods to determine the main characteristics to be included in literature from suppliers. ISO 6953-1 specifies which characteristics of compressed air pressure regulators are to be included in literature from their suppliers. ISO 6953-2 specifies test procedures and a method of presenting the results concerning the parameters which define the main characteristics to be included in literature from suppliers of regulators and filter-regulators conforming to ISO 6953‑1.
New Work Item Proposal to Revise ISO TS 11672 — Connectors for fluid power and general use — Designation and nomenclature. This Technical Specification collects the various designation and nomenclature schemes specified in International Standards for connectors and similar products standardized by ISO/TC 131/SC 4. It establishes a uniform nomenclature structure to facilitate standardization of product names used for threaded connectors, push‑in connectors, flanges, hose fittings, port plugs and quick-action couplings. The designation and nomenclature established in this Technical Specification are applicable for procurement purposes when agreed to by user and supplier.
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’s to SC 4, SC 5, SC 6 SC 7 and SC 8 will be reviewing 15 such 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 The individual Standard is either approved for another five years, recommended for a revision or withdrawn.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.
To learn about NFPA and the ISO Standards (draft, published, or withdrawn) relevant to fluid power go to NFPA’s Standards Locator.
