Full title and description

ASTM D4362-25 — Standard Specification for Propane Thermophysical Property Tables. This standard provides ready-to-use, tabulated thermophysical property data for pure propane (saturated liquid and vapor and selected T–p equilibrium states) intended for engineering calculations, process design, simulation and property look‑ups.

Abstract

Provides comprehensive thermophysical property tables for propane used to calculate pressure–volume–temperature (PVT), thermodynamic, and transport properties for engineering and process‑design applications. The tables include saturation (liquid and vapor) properties and tables at selected temperature and pressure points over a wide range; values are stated in SI units. The tables were produced using NIST’s REFPROP database models (published reference implementations used to derive the tabulated values).

Scope

This specification supplies tabulated thermophysical property data for propane required in engineering computations: two saturation tables (saturated liquid and saturated vapor) covering the low-temperature region up to the critical region, plus a third table of properties at selected temperature–pressure points for the equilibrium phase over an extended range (temperatures from roughly 90 K up to several hundred kelvin and pressures to the MPa range). Values are expressed in SI units only. The tabulations were produced from NIST REFPROP models to ensure internally consistent thermodynamic and transport properties for design and modelling.

Key topics and requirements

• Tabulated saturation properties for propane (separate liquid and vapor tables) covering the low‑temperature range through the critical region.
• Tabulated equilibrium T–p property points for extended temperature/pressure ranges useful in PVT and process calculations.
• Values presented exclusively in SI units; emphasis on internal consistency for simulation and hand calculations.
• Properties derived from NIST REFPROP formulations to provide vetted equations of state and transport property models.
• Intended accuracy and applicability statements for engineering use (see standard text for limits and recommended use ranges).

These are the principal technical elements users should expect when applying the tables.

Typical use and users

Used by chemical, petroleum, LNG and LPG process engineers, thermodynamicists, pipeline and storage designers, laboratory staff, and software developers who require reliable propane property data for simulation, equipment sizing, energy calculations, and safety analyses. The tables support hand calculations, spreadsheet tools and serve as reference inputs for process models.

FAQ

Q: What is this standard?

A: ASTM D4362-25 is the ASTM specification that provides tabulated thermophysical property tables for pure propane (saturated liquid, saturated vapor, and selected equilibrium T–p points) for engineering and process‑design use.

Q: What does it cover?

A: It covers the content, format and intended use of propane property tables (temperature and pressure ranges, property sets included such as density, enthalpy, entropy, specific heats, speed of sound and transport properties where tabulated), and specifies that values are given in SI units. The tables were generated from NIST REFPROP models; consult the standard for exact table limits and recommended application ranges.

Q: Who typically uses it?

A: Process and design engineers in the petrochemical, LPG/LNG and natural gas sectors, thermophysical researchers, flow‑computer and simulation software developers, and laboratories needing consistent property tables for calculations and verification.

Q: Is it current or superseded?

A: The designation D4362-25 indicates the 2025 revision; the standard is listed as active in the ASTM catalog and standards aggregators (publication date January 11, 2025). Users should check the official ASTM record for any subsequent amendments or errata.

Q: Is it part of a series?

A: D4362 is maintained under ASTM’s petroleum and fuels committee structure (committee/subcommittee responsible for physical properties tables). It is a standalone specification for propane tables but is commonly used alongside other fuel and hydrocarbon property standards and industry property compilations. See committee references in the standard for related work items.
