This specification covers methyl n-amyl ketone (98 % grade) for use in paint, varnish, lacquer, and related products. The apparent specific gravity, color, distillation range, water, acidity, and purity of the material shall be tested to meet the requirements prescribed.1.1 The thermophysical property tables for propane are used in calculating the pressure-volume-temperature (PVT), thermodynamic, and transport properties of propane for process design and operations. Two tables provide properties at the conditions of liquid-vapor equilibrium (saturation properties), one for liquid and one for vapor, at temperatures between 90 K and the critical point, 380 K. A third table provides properties at selected T, p points for the equilibrium phase at temperatures between 90 K and 600 K at pressures to 20 MPa. The tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 10.0.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
