21/30392376 DC

This standard 21/30392376 DC BS ISO 17584. Refrigerant properties is classified in these ICS categories:

• 71.100.45 Refrigerants and antifreezes

This International Standard specifies thermophysical properties of several commonly used refrigerants and refrigerant blends.

This International Standard is applicable to the refrigerants R12¹

, R22¹⁾, R32², R123¹⁾, R125²⁾, R134a²⁾, R143a²⁾, R152a²⁾, R290, R600a, R717 (ammonia), R744 (carbon dioxide), R1233zd(E), R1336mzz(Z), R1234yf and R1234ze(E) and to the refrigerant blends R404A²⁾, R407C²⁾, R410A²⁾, and R507A²⁾. The following properties are included: density, pressure, internal energy, enthalpy, entropy, heat capacity at constant pressure, heat capacity at constant volume, speed of sound, and the Joule-Thomson coefficient, in both single-phase states and along the liquid-vapour saturation boundary. The numerical designation of these refrigerants is that defined in ISO 817.
