ISO Standard 15171-2:2000 is a new standard published by the
National Fluid Power Association (NFPA) referencing couplings that may be used
in any hydraulic system that uses mineral oil.
The hydraulic system could be on a piece of mobile machinery (for
example, a tractor or bulldozer). Or it could be stationary industrial machinery
(for example, a press or robot).
"The scope of this standard indicates that the use of this
coupling with hydraulic fluids other than mineral oil requires a specific
agreement between the supplier and the purchaser," says Karen Boehme, NFPA's
International Standards Development Manager. "While couplings that conform to
ISO 15171-2 can be used at a maximum working pressure of 63 MPa (630 bar), they
can be connected or disconnected without tools only to a maximum pressure of 40
MPa (400 bar)."
NFPA is making the document available for $22.00 for NFPA members
and $28.00 for non-members. To order, contact NFPA's publication department at

One of the biggest walls in embedded software development is the integration of low-level drivers with higher-level middleware and application code, but silicon vendors are stepping up to bring it down.
