Indoor air - Part 24: Performance test for evaluating the reduction of volatile organic compound concentrations by sorptive building materials
This document specifies a general laboratory test method for evaluating the reduction in concentration
of VOCs by sorptive building materials. This method applies to boards, wallpapers, carpets, paint
products, and other building materials. The sorption of those target compound(s), i.e. VOCs, can be
brought about by adsorption, absorption and chemisorption. The performance of the material, with
respect to its ability to reduce the concentration of VOCs in indoor air, is evaluated by measuring
area-specific reduction rate and saturation mass per area. The former directly indicates material
performance with respect to VOC reduction at a point in time; the latter relates to the ability to maintain
that performance.
This document is based on the test chamber method specified in ISO 16000-9.
NOTE Sampling, transport and storage of materials to be tested, and preparation of test specimens, are
described in ISO 16000-11. Air sampling and analytical methods to determine VOCs are described in ISO 16000-6
and ISO 16017-1.

Introduction
Sorptive building materials have been marketed in the form of sheet and board products for removing
airborne pollutants via physical sorption or chemical reaction.
Harmonized test methods for evaluating sorptive effects are important for comparative assessment
of the performance of sorptive building materials that are used for reducing levels of indoor air
contaminants.
This document specifies a test method for evaluating the performance of sorptive building materials
for reducing indoor air volatile organic compound (VOC) concentrations over time.
The performance of sorptive building materials is evaluated by measuring the area-specific reduction
rate and the saturation mass per area and is affected by a number of factors. Specific test conditions are
therefore defined in this document.
This document can be applied to most sorptive building materials used indoors and for VOCs (excluding
formaldehyde).
This document is based on and is complementary to the test chamber method specified in ISO 16000-9.

5 Principle
The performance of a building material in reducing the concentration of target compound(s), i.e. VOCs,
from the indoor air, is evaluated by monitoring the reduction of the concentration inside a test chamber
containing a test specimen of that material. The test assesses both the initial performance of the
material and how long that performance is maintained.
In this test method, target compound-spiked air is supplied into a test chamber. The spiked air should
be prepared at approximately the guideline concentration level for target compound(s) in indoor
air. Reference to the WHO or an appropriate national standards body can be made if this is clearly
highlighted in the test report.
Performance is determined by monitoring the difference of the inlet and outlet concentration of the
test chamber. Testing should be continued for the half-lifetime, i.e. until the concentration reduction
performance of target compound(s) drops to half that at the start of the test under constant ventilation
conditions. This test determines area-specific reduction rate, ρ , and total mass per area of sorption, ρ ,
ads Ac
at the half-lifetime. The measured ρ at the half-lifetime is defined as the saturation mass per area, ρ .
Ac Aa
If a test material has a long-lasting target compound reduction performance (e.g. more than 28 days)
and the test might take too long a time, alternative methods specified in Annex A for determining ρ
Aa
may be applied.
The performance of sorptive building materials is mainly determined by the concentration of target
compound(s), the mass transfer coefficient of target compound(s) to the surface, and the sorption

---------------------- Page: 9 ----------------------
ISO 16000-24:2018(E)
characteristics of the building materials themselves (adsorption isotherm, diffusion resistance, and so
on). Therefore, the performance test method shall specify both the concentration of target compound(s)
and the mass transfer coefficient associated with the sorptive building materials.
A re-emission test should be conducted following the test for evaluating concentration reduction
performance, the procedure for which is described in 11.3.1.
NOTE The long-term target compound reduction performance is represented by the saturation mass per
area, ρ , and, if necessary, the lifetime of the pollutant-removing performance, t , as the subsidiary index.

6 Apparatus and materials
The usual laboratory apparatus and, in particular, the following.
6.1 Test chamber, complying with relevant specifications and requirements of ISO 16000-9
(see Figure 1). No air shall be allowed to circulate from the outlet back to the inlet.
Key
1 target compound(s) in spiked air (6.3) 5 device to circulate air and control air velocity
2 air sampling device (6.6) 6 temperature/humidity monitoring apparatus (6.4)
3 test specimen 7 test chamber outlet
4 test chamber (6.1) 8 air sampling device (6.6)
Figure 1 — Outline of the test chamber system
6.2 Air purifier or cylinder of clean air, to ensure the supply air before being spiked with target
compound(s) is as clean as possible, i.e. it shall not contain any contaminants at levels greater than the
chamber background requirements.
6.3 Supply air spiked with target compound(s), created by applying a standard gas (with known
target compound concentrations). Alternatively, use a stable source to generate air spiked with target
compound(s) that can be to supplied to the test chamber at a constant concentration. The stability of the
spiked concentration(s) shall be monitored.
The spiked concentration(s) should be determined at least twice (at the beginning and end of the test).
6.4 Temperature and humidity monitoring apparatus.
Temperature shall be maintained either by installing a test chamber in a place maintained at a required
temperature, or by maintaining a required temperature in the chamber. Relative humidity shall be
maintained at the required humidity of the supply air.
© ISO 2018 – All rights reserved 5
---------------------- Page: 10 ----------------------
ISO 16000-24:2018(E)
6.5 Air flow meter, installed at the inlet or the outlet of the test chamber to measure the air flow rate
through the chamber.
6.6 Air sampling devices, to sample the inlet and outlet air of the test chamber. When a separate
sampling port is used, sample directly from the inlet or outlet of the chamber.
If a duct or tube is used, it shall be as short as possible and kept at the same air temperature as that in
the test chamber. Such a duct or tube shall be made of a material with a very low sorption capacity, e.g.
polytetrafluoroethylene.
The sum of sampling air flow rates shall be smaller than the air flow rate into the chamber. Sampling
devices shall comply with the specifications of ISO 16000-3 and ISO 16000-6, respectively. When the air
is sampled from the inlet, ensure the supply air flow rate remains constant.
A multiport sampling manifold may be used to provide flexibility for duplicate air sampling. A mixing
chamber between the test chamber and the manifold or between the air inlet and the test chamber can
be included to permit addition and mixing of internal standard gases with the test chamber air stream.
The exhaust from the test chamber should be ducted into a fume hood, ensuring any chemicals emitted
from the test material are isolated from the laboratory environment.
6.7 Analytical instrument. For determination of VOCs, a gas chromatograph (GC) shall be used as
specified in ISO 16000-6 and ISO 16017-1. Alternative devices with an equal or better accuracy may
be used.
7 Test conditions
7.1 General
The test conditions shall comply with 7.2 and 7.3. This test shall be conducted under atmospheric
pressure conditions.
7.2 Test conditions to determine concentration reduction performance
7.2.1 Temperature and relative humidity
The temperature in the test chamber should be set to 23 °C ± 1 °C, and relative humidity should be
50 % ± 5 % during the test.
For building materials with applications under other climatic conditions, alternative temperature and air
humidity conditions may be used, preferably as specified in ISO 554. State the conditions in the test report.
To check the test material for temperature dependence of reduction performance, measurements under
other climatic conditions may be applied.
Initial variations can be observed in the test chamber climate after opening the test chamber door and
loading a test specimen. These variations should be recorded.
NOTE Temperature and relative humidity can affect area-specific reduction rate and re-desorption from the
test material.
7.2.2 Supply air quality and background concentration
The background concentration of the supply air for the test chamber and the air prior to spiking with
target compound(s) shall be low enough not to interfere with the test. The total VOC background
3
concentration shall be lower than 20 µg/m . The background concentration of each VOC shall be lower
3
than 2 µg/m . Purified water used for humidification shall not contain interfering VOCs that can affect
the test.

ISO 16000-24:2018(E)
7.2.3 Mass transfer coefficient
The mass transfer coefficient in terms of ambient air velocity over the surface of the test specimen
inside the chamber shall be 15 m/h ± 3 m/h (equivalent to 0,25 m/s ± 0,05 m/s) when determined using
water vapour. To check the dependence of the mass transfer coefficient on material performance, take
measurements under conditions that appropriately influence the mass transfer coefficient.
NOTE 1 The mass transfer coefficient is analogous to the convective heat transfer coefficient where geometry
and boundary conditions are similar. The mass transfer coefficient can be estimated with a formulation that
relates the mass transfer flux (area-specific reduction rate) to a surface to the concentration differences across
the boundary layer. For detai

Introduction
Sorptive building materials have been marketed in the form of sheet and board products for removing
airborne pollutants via physical sorption or chemical reaction.
Harmonized test methods for evaluating sorptive effects are important for comparative assessment
of the performance of sorptive building materials that are used for reducing levels of indoor air
contaminants.
This document specifies a test method for evaluating the performance of sorptive building materials
for reducing indoor air volatile organic compound (VOC) concentrations over time.
The performance of sorptive building materials is evaluated by measuring the area-specific reduction
rate and the saturation mass per area and is affected by a number of factors. Specific test conditions are
therefore defined in this document.
This document can be applied to most sorptive building materials used indoors and for VOCs (excluding
formaldehyde).
This document is based on and is complementary to the test chamber method specified in ISO 16000-9.

Part 24:
Performance test for evaluating the reduction of volatile
organic compound concentrations by sorptive building
materials
1 Scope
This document specifies a general laboratory test method for evaluating the reduction in concentration
of VOCs by sorptive building materials. This method applies to boards, wallpapers, carpets, paint
products, and other building materials. The sorption of those target compound(s), i.e. VOCs, can be
brought about by adsorption, absorption and chemisorption. The performance of the material, with
respect to its ability to reduce the concentration of VOCs in indoor air, is evaluated by measuring
area-specific reduction rate and saturation mass per area. The former directly indicates material
performance with respect to VOC reduction at a point in time; the latter relates to the ability to maintain
that performance.
This document is based on the test chamber method specified in ISO 16000-9.
NOTE Sampling, transport and storage of materials to be tested, and preparation of test specimens, are
described in ISO 16000-11. Air sampling and analytical methods to determine VOCs are described in ISO 16000-6
and ISO 16017-1.

5 Principle
The performance of a building material in reducing the concentration of target compound(s), i.e. VOCs,
from the indoor air, is evaluated by monitoring the reduction of the concentration inside a test chamber
containing a test specimen of that material. The test assesses both the initial performance of the
material and how long that performance is maintained.
In this test method, target compound-spiked air is supplied into a test chamber. The spiked air should
be prepared at approximately the guideline concentration level for target compound(s) in indoor
air. Reference to the WHO or an appropriate national standards body can be made if this is clearly
highlighted in the test report.
Performance is determined by monitoring the difference of the inlet and outlet concentration of the
test chamber. Testing should be continued for the half-lifetime, i.e. until the concentration reduction
performance of target compound(s) drops to half that at the start of the test under constant ventilation
conditions. This test determines area-specific reduction rate, ρ , and total mass per area of sorption, ρ ,
ads Ac
at the half-lifetime. The measured ρ at the half-lifetime is defined as the saturation mass per area, ρ .
Ac Aa
If a test material has a long-lasting target compound reduction performance (e.g. more than 28 days)
and the test might take too long a time, alternative methods specified in Annex A for determining ρ
Aa
may be applied.
The performance of sorptive building materials is mainly determined by the concentration of target
compound(s), the mass transfer coefficient of target compound(s) to the surface, and the sorption

characteristics of the building materials themselves (adsorption isotherm, diffusion resistance, and so
on). Therefore, the performance test method shall specify both the concentration of target compound(s)
and the mass transfer coefficient associated with the sorptive building materials.
A re-emission test should be conducted following the test for evaluating concentration reduction
performance, the procedure for which is described in 11.3.1.
NOTE The long-term target compound reduction performance is represented by the saturation mass per
area, ρ , and, if necessary, the lifetime of the pollutant-removing performance, t , as the subsidiary index.

6 Apparatus and materials
The usual laboratory apparatus and, in particular, the following.
6.1 Test chamber, complying with relevant specifications and requirements of ISO 16000-9
(see Figure 1). No air shall be allowed to circulate from the outlet back to the inlet.
Key
1 target compound(s) in spiked air (6.3) 5 device to circulate air and control air velocity
2 air sampling device (6.6) 6 temperature/humidity monitoring apparatus (6.4)
3 test specimen 7 test chamber outlet
4 test chamber (6.1) 8 air sampling device (6.6)
Figure 1 — Outline of the test chamber system
6.2 Air purifier or cylinder of clean air, to ensure the supply air before being spiked with target
compound(s) is as clean as possible, i.e. it shall not contain any contaminants at levels greater than the
chamber background requirements.
6.3 Supply air spiked with target compound(s), created by applying a standard gas (with known
target compound concentrations). Alternatively, use a stable source to generate air spiked with target
compound(s) that can be to supplied to the test chamber at a constant concentration. The stability of the
spiked concentration(s) shall be monitored.
The spiked concentration(s) should be determined at least twice (at the beginning and end of the test).
6.4 Temperature and humidity monitoring apparatus.
Temperature shall be maintained either by installing a test chamber in a place maintained at a required
temperature, or by maintaining a required temperature in the chamber. Relative humidity shall be
maintained at the required humidity of the supply air.

SIST ISO 16000-24:2019
ISO 16000-24:2018(E)
6.5 Air flow meter, installed at the inlet or the outlet of the test chamber to measure the air flow rate
through the chamber.
6.6 Air sampling devices, to sample the inlet and outlet air of the test chamber. When a separate
sampling port is used, sample directly from the inlet or outlet of the chamber.
If a duct or tube is used, it shall be as short as possible and kept at the same air temperature as that in
the test chamber. Such a duct or tube shall be made of a material with a very low sorption capacity, e.g.
polytetrafluoroethylene.
The sum of sampling air flow rates shall be smaller than the air flow rate into the chamber. Sampling
devices shall comply with the specifications of ISO 16000-3 and ISO 16000-6, respectively. When the air
is sampled from the inlet, ensure the supply air flow rate remains constant.
A multiport sampling manifold may be used to provide flexibility for duplicate air sampling. A mixing
chamber between the test chamber and the manifold or between the air inlet and the test chamber can
be included to permit addition and mixing of internal standard gases with the test chamber air stream.
The exhaust from the test chamber should be ducted into a fume hood, ensuring any chemicals emitted
from the test material are isolated from the laboratory environment.
6.7 Analytical instrument. For determination of VOCs, a gas chromatograph (GC) shall be used as
specified in ISO 16000-6 and ISO 16017-1. Alternative devices with an equal or better accuracy may
be used.
7 Test conditions
7.1 General
The test conditions shall comply with 7.2 and 7.3. This test shall be conducted under atmospheric
pressure conditions.
7.2 Test conditions to determine concentration reduction performance
7.2.1 Temperature and relative humidity
The temperature in the test chamber should be set to 23 °C ± 1 °C, and relative humidity should be
50 % ± 5 % during the test.
For building materials with applications under other climatic conditions, alternative temperature and air
humidity conditions may be used, preferably as specified in ISO 554. State the conditions in the test report.
To check the test material for temperature dependence of reduction performance, measurements under
other climatic conditions may be applied.
Initial variations can be observed in the test chamber climate after opening the test chamber door and
loading a test specimen. These variations should be recorded.
NOTE Temperature and relative humidity can affect area-specific reduction rate and re-desorption from the
test material.

Introduction
Les matériaux de construction sorptifs ont été mis sur le marché sous forme de produits en film et en
planche servant à éliminer les polluants aériens par sorption physique ou par réaction chimique.
La normalisation des méthodes d’essai relatives à l’évaluation des effets sorptifs est essentielle pour
effectuer une analyse comparative des performances des matériaux de construction sorptifs utilisés
pour réduire les niveaux des contaminants dans l’air intérieur.
Le présent document spécifie une méthode d’essai pour l’évaluation des performances, dans le temps,
des matériaux de construction sorptifs en matière de réduction des concentrations en composés
organiques volatils (COV) dans l’air intérieur.
La performance des matériaux de construction sorptifs est évaluée par mesurage du taux de réduction
spécifique par unité de surface et de la masse surfacique de saturation, et elle est affectée par plusieurs
facteurs. Des conditions d’essai spécifiques sont par conséquent définies dans le présent document.
Le présent document peut s’appliquer à la majorité des matériaux de construction sorptifs utilisés en
intérieur ainsi qu’aux COV (à l’exception du formaldéhyde).
Le présent document s’appuie sur, et est complémentaire de, la méthode de la chambre d’essai spécifiée

de sa capacité de réduction de la concentration en COV en air intérieur, est évaluée en mesurant le taux
de réduction spécifique par unité de surface et la masse surfacique de saturation. Le premier indique
directement la performance d’un matériau en fonction de la réduction de la concentration en COV à un
instant donné; la dernière indique la capacité d’un produit à maintenir cette performance.
Le présent document s’appuie sur la méthode de la chambre d’essai spécifiée dans l’ISO 16000-9.
NOTE L’échantillonnage, le transport et le stockage des matériaux à soumettre à essai, ainsi que la
préparation des éprouvettes, sont décrits dans l’ISO 16000-11. Le prélèvement de l’air et les méthodes d’analyse
en vue de la détermination des COV sont décrits dans l’ISO 16000-6 et l’ISO 16017-1.

5 Principe
La performance d’un matériau de construction en matière de réduction de la concentration en
composé(s) cible(s), à savoir les COV, dans l’air intérieur, est évaluée en surveillant la réduction de la
concentration à l’intérieur d’une chambre d’essai contenant une éprouvette du matériau soumis à essai.
L’essai évalue la performance initiale du matériau ainsi que la durée pendant laquelle la performance
est maintenue.
Dans cette méthode d’essai, la chambre d’essai est alimentée avec de l’air dopé avec le(s) composé(s)
cible(s). Il convient de préparer l’air dopé approximativement à la concentration de référence pour
le(s) composé(s) cible(s) dans l’air intérieur. Il est possible de faire référence à l’OMS ou à un organisme
national de normalisation approprié si le rapport d’essai l’indique clairement.
La performance est déterminée en observant la différence de concentration en COV cibles entre l’entrée
et la sortie de la chambre d’essai. Il convient de continuer l’essai pendant la moitié de la durée de vie,
c’est-à-dire jusqu’à ce que la performance en matière de réduction de la concentration en composé(s)
cible(s) soit réduite à la moitié de celle constatée au début de l’essai dans des conditions de ventilation
constantes. Cet essai détermine le taux de réduction spécifique par unité de surface, ρ , et la masse
ads
surfacique totale de sorption, ρ , à la moitié de la durée de vie. La valeur ρ mesurée à la moitié de la
Ac Ac
durée de vie est définie comme la masse surfacique de saturation, ρ .
Aa

---------------------- Page: 10 ----------------------
ISO 16000-24:2018(F)
Si la performance d’un matériau d’essai en matière de réduction de la concentration en composé(s)
cible(s) est, par exemple de plus de 28 jours et qu’un essai en chambre peut se révéler trop long, il est
possible d’appliquer d’autres méthodes, spécifiées à l’Annexe A, pour la détermination de ρ .
Aa
Les performances des matériaux de construction sorptifs sont déterminées en grande partie par la
concentration en composé(s) cible(s), le coefficient de transfert massique du ou des composés cibles
à leur surface, ainsi que les caractéristiques de sorption des matériaux de construction (isotherme
d’adsorption, résistance à la diffusion, etc.). De ce fait, la méthode d’essai relative aux performances
doit spécifier la concentration en composé(s) cible(s) et le coefficient de transfert massique associés aux
matériaux de construction sorptifs.
Il convient de réaliser un essai de réémission à la suite de l’essai permettant d’évaluer les performances
en matière de réduction de la concentration, dont le mode opératoire est décrit en 11.3.1.
NOTE La performance longue durée en matière de réduction de la concentration en composé(s) cible(s) est
représentée par la masse surfacique de saturation, ρ , avec, si nécessaire, la durée de vie de la performance
Aa
d’élimination des polluants, t , en indicateur secondaire.

contaminants à des niveaux qui dépassent ceux spécifiés pour la concentration de fond de la chambre
d’essai.
6.3 Alimentation en air dopé avec le(s) composé(s) cible(s), réalisée en introduisant dans la

doit être surveillée.
Il convient que la ou les concentrations dopées soient déterminées au moins deux fois (au début et à la
fin de l’essai).
6.4 Dispositif de contrôle de la température et de l’humidité.
La température doit être contrôlée soit par l’installation d’une chambre d’essai dans un lieu maintenu
à la température requise, soit par le maintien de la température requise dans la chambre. L’humidité
relative doit être maintenue au niveau d’humidité requis de l’air d’alimentation.

d’essai. En cas d’utilisation d’un port de prélèvement distinct, prélever directement à l’entrée ou à la
sortie de la chambre.
En cas d’utilisation d’un tuyau ou d’un tube, ce dernier doit être le plus court possible et l’air doit y être
maintenu à la même température que celle de la chambre d’essai. Un tuyau ou tube de ce type doit être
fabriqué dans un matériau d’une capacité de sorption très faible, par exemple du polytétrafluoroéthylène.
La somme des débits d’air de prélèvement doit être inférieure au débit d’air entrant dans la chambre.
Les dispositifs de prélèvement doivent être conformes aux spécifications de l’ISO 16000-3 et de
l’ISO

Introduction
Sorptive building materials have been marketed in the form of sheet and board products for removing
airborne pollutants via physical sorption or chemical reaction.
Harmonized test methods for evaluating sorptive effects are important for comparative assessment
of the performance of sorptive building materials that are used for reducing levels of indoor air
contaminants.
This part of ISO 16000 specifies a test method for evaluating the performance of sorptive building
materials for reducing indoor air volatile organic compound (VOC) concentrations over time.
The performance of sorptive building materials is evaluated by area specific reduction rate and
saturation mass per area and is affected by a number of factors. Specific test conditions are therefore
defined in this part of ISO 16000.
This part of ISO 16000 can be applied to most sorptive building materials used indoors and for VOCs
(excluding formaldehyde).
This part of ISO 16000 is based on and is complementary to the test chamber method specified in
ISO 16000-9.

DRAFT INTERNATIONAL STANDARD ISO/DIS 16000-24:2017(E)
Indoor air —
Part 24:
Performance test for evaluating the reduction of volatile
organic compound concentrations by sorptive building
materials
1 Scope
This part of ISO 16000 specifies a general laboratory test method for evaluating the reduction in
concentration of volatile organic compounds (VOCs) by sorptive building materials. This method
applies to boards, wallpapers, carpets, paint products, and other building materials. The sorption of
those target compound(s), i.e. VOCs can be brought about by adsorption, absorption and chemisorption.
The performance of the material, with respect to its ability to reduce the concentration of VOCs in
indoor air, is evaluated by measuring area specific reduction rate and saturation mass per area. The
former directly indicates material performance with respect to VOC reduction at a point in time; the
latter relates to the ability to maintain that performance.
This part of ISO 16000 is based on the test chamber method specified in ISO 16000-9. Sampling,
transport and storage of materials to be tested, and preparation of test specimens are described in
ISO 16000-11. Air sampling and analytical methods for the determination of VOCs are described in
ISO 16000-6 and ISO 16017-1.
