Notes
- Ref. CRC: Values refer to 27 °C unless noted.
- Ref. CR2: Values refer to 300 K and a pressure of "100 kPa (1 bar)", or to the saturation vapor pressure if that is less than 100 kPa. The notation (P=0) denotes low pressure limiting values.
- Ref. LNG: Values refer to 300 K.
- Ref. WEL: Values refer to 25 °C.
