Two new ISO standards have recently been published and are now available from the National Fluid Power Association (NFPA), Milwaukee.
The first, "ISO 14540:2013, Hydraulic fluid power — Dimensions and requirements for screw-to-connect quick-action couplings for use at a pressure of 72 MPa (720 bar)," is an international standard taht specifies dimensional and performance requirements for hydraulic screw-to-connect quick-action couplings designed to be used at pressure of 72 MPa (720 bar) in static conditions as an interface between a hydraulic power unit and a tool. Typical applications for these couplings are related to hydraulic jacks, rams, clamping devices, hand tools, and cylinders.
ISO 14540 covers two types of such couplings: the "P" type, which has a poppet valve, and the "S" type, which has a spherical valve.
Benefits — This dimensional interchangeability standard benefits users by allowing them to purchase hydraulic quick-action couplings from multiple suppliers, and manufacturers of these coupling to benefit from economies of scale afforded by the standard.
NFPA list price: $61.00; NFPA member price: $48.00.


The second is "ISO 14541:2013, Hydraulic fluid power— Dimensions and requirements for screw-to-connect quick-action couplings for general purpose."
This international standard specifies the dimensional and performance requirements for hydraulic screw-to-connect quick-action couplings for general use.
Benefits — This dimensional interchangeability standard benefits users by allowing them to purchase hydraulic quick-action couplings from multiple suppliers, and manufacturers of these coupling to benefit from economies of scale afforded by the standard.
NFPA list price: $61.00; NFPA member price: $48.00
