Specifies a method for calculating temperatures and corresponding vapour pressures of fluids in vessels subject to atmospheric heating in the hottest month of the year in various locations around Australia. The method is applicable to stationary and transport vessels containing compressed liquefied gases, permanent gases and liquids having a viscosity not exceeding approximately 1Pa.s.

This Standard sets out a method for calculating temperatures and the corresponding vapour pressures of fluids in vessels subject to atmospheric heating in the hottest month of the year in various locations around Australia. It is primarily intended for compressed liquefied gases stored in steel containers, and is equally applicable to stationary as well as transport vessels. Because the method is quite general it may also be used for permanent gases and liquids, provided that the liquids are not too viscous (upper limit approximately 1 Pa.s). It may also be used for above-ground pipelines. Some characteristic properties of a number of fluids are shown graphically in Appendix A.NOTES:1 Sample calculations are shown in appendix B.2 The theoretical background for the method given in this Standard is given in Appendix C.
