This Standard covers a 60°F relative density range of 0.3500 to 0.6880 which nominally equates to a density at 15°C of 351.7 to 687.8 kg/m3 and a density at 20°C of 331.7 to 683.6 kg/m3. The temperature range of this Standard is -50.8 to 199.4°F (-46 to 93°C). At all conditions, the pressure is assumed to be at saturation conditions (also known as bubble point or saturation vapor pressure).
