| Definition: | helium at pressure, p , and/or temperature, T, above the critical point (p > 227 kPa, T > 5,2 K), which is characterized by zero latent heat of vaporization and a continuous density function
Note 1 to entry: In magnet cooling applications, high-pressure (> 227 kPa) helium near 4,2 K is also called "supercritical helium". Note 2 to entry: This entry was numbered 815-15-17 in IEC 60050-815:2015.
