Curation notes

Identity VALIDATED_WITH_WARNINGS by the library (an equation warning on pdf p. 38). Pages are pdf pages.

IDEAL GAS AND CONSTANTS: M = 44.0098(16) g/mol (p. 6), R = 8.314510 J/(mol K) (p. 7); the ideal-gas part (Eq. 6.2, p. 36; Table 27, p. 33) agrees with Chao’s values to +-0.002 % from 210 K to 1500 K. Range 216.592-1100 K, 800 MPa.

AGAINST COOLPROP 8.0.0 (reference key Span-JPCRD-1996): the same M, R and ideal part (computed 2026-09-30).
