Frequently Asked Questions

ISO/TC 86/SC 8/WG 7 is a Subcommittee within the International Organization for Standardization (ISO). It is named "Refrigerant properties". This committee has published 1 standards.

ISO/TC 86/SC 8/WG 7 develops ISO standards in the area of Information technology. Currently, there are 1 published standards from this subcommittee.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.

A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.

Refrigerant properties

This document specifies the thermophysical properties of several commonly used refrigerants and refrigerant blends. This document is applicable to refrigerants R12, R22, R32, R123, R125, R134a, R143a, R152a, R290, R600a, R717 (ammonia), R744 (carbon dioxide), R1233zd(E), R1336mzz(Z), R1234yf and R1234ze(E) and to the refrigerant blends R404A, R407C, R410A, and R507A. 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. NOTE 1 R12, R22, R123 are controlled substances under the Montreal Protocol, Annex A (R12) or Annex C Group I (R22, R123). NOTE 2 R32, R125, R134a, R143a, R152a, R404A, R407C, R410A, and R507A are controlled substances under the Montreal Protocol, Annex F or blend thereof.
