This section is a non-exhaustive list of standards by the International Organization for Standardization (ISO) related to acoustical porous materials.
| REFERENCE | DESCRIPTION | COMMENT |
|---|---|---|
| ISO 3 | Preferred Numbers -- Series of Preferred Numbers | Read more about this standard used to defined octave, third-octave bands... |
| ISO 354 | Acoustics -- Measurement of sound absorption in a reverberation room | |
| ISO 717 series | Acoustics -- Rating of sound insulation in buildings and of building elements | |
| ISO 4590 | Rigid cellular plastics -- Determination of the volume percentage of open cells and of closed cells | Not consistent for acoustical porous media with open porosities close to 1 |
| ISO 6721 series | Plastics -- Determination of dynamic mechanical properties | Limited to elastic properties and moduli |
| ISO 9052-1:1989 | Acoustics -- Determination of dynamic stiffness -- Part 1: Materials used under floating floors in dwellings | Multiple requests to revise this standard. No other parts than -1. |
| ISO 9053-1:2018 | Acoustics -- Materials for acoustical applications -- Determination of airflow resistance -- Part 1: static method | Used to be ISO 9053, method A. A new information appendix introduced the estimation from impedance tube measurements. |
| Imposed pressure drops imply velocities 2 orders of magnitude higher than ISO 9053. This method thus cannot be compared to ISO 9053 and is not recommend for acoustical materials. |

| ISO 10140 series | Acoustics -- Laboratory measurement of sound insulation of building elements | |
| ISO 10534 series | Acoustics -- Determination of sound absorption coefficient and impedance in impedance tubes | -2 currently in revision, -3 and -4 are being created. |
| ISO 11654 | Acoustics -- Sound absorbers for use in buildings -- Rating of sound absorption | Note that other ratings are used in ASTM standards, in particular ASTM C423 introducing the SAA (Sound Absorption Average) which replaces the obsolete NRC (Noise Reduction Coefficient) |
| ISO 13472 series | Acoustics -- Measurement of sound absorption properties of road surfaces in situ | |
| ISO 18437 series | Mechanical vibration and shock -- Characterization of the dynamic mechanical properties of visco-elastic materials | Limited to elastic properties. Part 5 is dedicated to "Poisson ratio based on comparison between measurements and finite element analysis" |
