Table 2.12 on page 20 should be corrected as follows:

Revision of page 21
The last paragraph on page 20 continuing on page 21 should be completed as follows:
| Range of Validity. Equation (2.9) is valid in the metastable-vapour region from the saturated-vapour line to the 5% equilibrium moisture line (corresponding to the vapour fraction x = 0.95, determined from the equilibrium h' and h'' values calculated for the given pressure) at pressures from the triple-point pressure, see Eq. (1.8), up to 10 MPa. |
Correction on page 40
The values for h' (623.15 K) and h'' (623.15 K) in the paragraph below Table 2.29 on page 40 should be corrected as follows:
The equation ps,3 ( h ), Eq. (2.18), describes the saturated-liquid line and the saturated-vapour line including the critical point in the following enthalpy range, see Fig. 2.5:
where h' (623.15 K) = h1( ps(623.15 K), 623.15 K) = 1.670 858 218 x 103 kJ kg-1 and h'' (623.15 K) = h2( ps(623.15 K), 623.15 K) = 2.563 592 004 x 103 kJ kg-1 |

The headline of Table 2.71 on page 83 should be corrected as follows:

Correction on page 130
Table 2.132 on page 130 should be corrected as follows:

Revision of page 152
The paragraph below Eq. (3.3) must be corrected into:
| where d = r/r* and θ = T/T* with r* = rc and T* = Tc, where the critical density rc = 322 kg m-3 and the critical temperature Tc = 647.096 K according to Eqs. (1.6) and (1.4). Table 3.2 contains the coefficients ni and exponents Ii and Ji of Eq. (3.3). |

Correction of certain results calculated from the attached IAPWS-IF97 Electronic Steam Tables CD
There is an error in the conversion of kJ/(kg K) into BTU/(lbm °R) that relates to the properties
| specific entropy s, isobaric heat capacity cp, isochoric heat capacity cv, and specific gas constant R. |
The displayed results for these properties in BTU/(lbm °R) have to be divided by 1.8.
