This AIR is arranged in the following two sections: 2E - thermodynamic characteristics of working fluids, which contains thermodynamic diagrams for a number of working fluids currently in use and supplied by various industrial firms; and 2F - properties of heat transfer fluids, which contains data, primarily in graphical form, on fluids that are frequently used in fluid heat transfer loops. Other properties of the environment, gases, liquids, and solids, can be found, as follows, in AIR 1168/9: 2A-Properties of the natural environment; 2B-Properties of gases; 2C-Properties of liquids and 2D- Properties of solids.
The Technical Committee has determined that additional fluids are now in common use and new fluids continue to be developed. Fluid data is now readily available on the internet to a higher fidelity than is possible to put into AIR1168/10. The information presently included in AIR1168/10 is accurate although some of the fluids are no longer in common use. The Technical Committee recommends to stabilize this document.
