In previous sections of this book (Section 524 and Section 533) the transport properties (viscosity and thermal conductivity) of various liquids and gases have been given at saturation pressure and temperature, or at atmospheric pressure and temperature, or at atmospheric pressure (Section 534). However, the effect of pressure is considerable, and this section gives a selection of data for various substances at elevated pressure. The boiling point is given in Kelvins for each pressure to mark the change from liquid to vapour.

The tables are reproduced from the best sets currently available in the literature, and the sources are given. The tables for almost all substances in previous editions have been completely revised.

Data are presented for the following substances:
