Description	28-31 Four equations of state for solids with adjustable parameter K'∞, the pressure derivative of bulk modulus at infinite pressure have been studied. These equations are the Keane EOS, the Stacey reciprocal K' - EOS, the generalized Rydberg EOS and the Roy-Roy EOS. It is found that the Keane EOS and the Stacey EOS are very similar requiring K'∞ to be considerably larger than 5/3. The generalized Rydberg EOS yields satisfactory results with a value of K'∞ = 5/3. For the Roy-Roy EOS, K'∞ has been found to remain between 5/3 and 2. This has been demonstrated by calculating P, K and K' for hcp iron at different compressions.
