ASTM D7265-23

Standard Specification for Hydrogen Thermophysical Property Tables

SCOPE
1.1 The thermophysical property tables for normal hydrogen are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of hydrogen for process design and operations, particularly as they relate to hydrogen fuel cell applications. Tables are provided for gaseous hydrogen at temperatures between 50 K and 500 K at pressures to 500 MPa. These tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 10.02.  
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D7265-23 defines the standard specification for hydrogen thermophysical property tables, providing critical data for calculating pressure-volume-temperature (PVT), thermodynamic, and transport properties of normal hydrogen. These extensive tables, developed by the National Institute of Standards and Technology (NIST) based on their REFPROP software database, cover gaseous hydrogen at temperatures from 50 K to 500 K and pressures up to 500 MPa. The standard is intended for use in process design and operations, with a strong focus on hydrogen fuel cell applications.

Key Topics

• Hydrogen Thermophysical Data: The standard offers detailed values for key properties, including:

  • Molar density
  • Molar volume
  • Molar enthalpy
  • Molar entropy
  • Constant volume molar heat capacity (Cv)
  • Constant pressure molar heat capacity (Cp)
  • Speed of sound
  • Viscosity
  • Thermal conductivity

• Reference States: The property tables use standard reference states for enthalpy and entropy at 298.15 K and 0.101325 MPa, ensuring consistency and accuracy in calculations.

• Comprehensive Coverage: Tables are provided for a wide range of pressures and temperatures, including newly added tables for 35 MPa (350 bar) and 70 MPa (700 bar) - typical hydrogen fuel cell vehicle pressures.

• Intended Use: While the data is strictly for pure gaseous hydrogen, the tables can be valuable in developing mathematical models for hydrogen-containing mixtures.

• Standardized Approach: The document adheres to internationally recognized principles of standardization in line with World Trade Organization (WTO) guidelines on technical barriers to trade.

Applications

• Hydrogen Fuel Cell Systems: Essential for the design and operational analysis of hydrogen storage and dispensing systems in fuel cell vehicles and stationary applications.

• Process Design in Industry: Provides a reliable foundation for engineering calculations involving hydrogen, such as pipeline transport, storage facilities, and energy systems.

• Research and Development: Enables consistent thermodynamic and transport property data for simulation and modeling in academic and industrial research settings.

• Safety and Compliance: Facilitates adherence to safety standards by providing accurate hydrogen property data for risk assessment and engineering controls.

• Software Integration: The property tables are compatible with engineering software applications, particularly those utilizing the NIST REFPROP database, supporting automated calculations and system optimization.

Related Standards

To support and complement the use of ASTM D7265-23, consider the following related standards:

• ASTM D4150: Terminology Relating to Gaseous Fuels
• REFPROP (NIST Reference Fluid Thermodynamic and Transport Properties Database): The foundational data source for creating the property tables in D7265-23
• Additional hydrogen-related standards issued by ASTM Committee D03 on Gaseous Fuels

Practical Value

Engineers, researchers, and designers in the hydrogen energy sector rely on accurate, standardized data to achieve efficient, safe, and innovative solutions. ASTM D7265-23 fulfills this need by providing trusted property tables that underpin wide-ranging hydrogen applications, particularly in the rapidly growing sector of hydrogen fuel cell technology.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D7265 − 12 (Reapproved 2018) D7265 − 23
Standard Specification for
Hydrogen Thermophysical Property Tables
This standard is issued under the fixed designation D7265; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 The thermophysical property tables for normal hydrogen are for use in the calculation of the pressure-volume-temperature
(PVT), thermodynamic, and transport properties of hydrogen for process design and operations, particularly as they relate to
hydrogen fuel cell applications. Tables are provided for gaseous hydrogen at temperatures between 50 K and 500 K at pressures
to 50500 MPa. These tables were developed by the National Institute of Standards and Technology from a Standard Reference
Database product REFPROP, version 9.0.10.0 .
1.2 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
2. Referenced Documents
2.1 ASTM Standards:
D4150 Terminology Relating to Gaseous Fuels
3. Applicability
3.1 These tables apply directly only to pure gaseous hydrogen. However, it is expected that they may find substantial use in
mathematical models and tables for the thermophysical properties of mixtures containing hydrogen.
4. Terminology
4.1 Definitions—For definitions of general terms used in D03 Gaseous Fuels standards, refer to Terminology D4150.
5. Tables
5.1 The tabulated thermophysical properties are:
-1
ρ, molar density (mol·L )
-1
V, molar volume (L ·mol)
-1
H, molar enthalpy (J·mol )
-1 -1
S, molar entropy (J·K ·mol )
This specification is under the jurisdiction of ASTM Committee D03 on Gaseous Fuels and is the direct responsibility of Subcommittee D03.08 on Thermophysical
Properties.
Current edition approved April 1, 2018Nov. 1, 2023. Published May 2018January 2024. Originally approved in 2006. Last previous edition approved in 20122018 as

5.2 These tables were produced by equations from a computer package, “NIST Standard Reference Database 23; Reference Fluid
Thermodynamic and Transport Properties Database (REFPROP): Version 9.0.”10.0.” A wide selection of units (SI units,
engineering units, chemical units) is available with this program.
6. Additional Information
6.1 The Reference States for enthalpy and entropy have been updated in this version of the Standard.
6.2 A comprehensive equation of state for normal hydrogen is not available at this time. The properties in the table were calculated
from individual equations for normal hydrogen.Reference state properties are required to calculate certain of the thermodynamic
properties (enthalpy, entropy, etc.) from an equation of state formulation.
6.3 The reference state properties used to generate the tables in this specification are: enthalpy, H, and entropy, S, at 298.15 K and
0.101325 MPa (H = 10018 J ⁄mol and S = 186.266 J/(mol K)). The molar mass of hydrogen is 2.0159 g/mol.
6.4 Two new tables have been added at 35 Mpa (350 Bar) and 70 Mpa (700 Bar). These are the most common fuel pressures used
for vehicles using hydrogen fuel cells.
