Indoor air - Part 10: Determination of the emission of volatile organic compounds from building products and furnishing - Emission test cell method (ISO 16000-10:2006)
This part of ISO 16000 specifies a general laboratory test method for determination of the area specific emission rate of volatile organic compounds (VOCs) from newly produced building products or furnishing under defined climate conditions. The method can in principle also be applied to aged products. The emission data obtained can be used to calculate concentrations in a model room. According to the definition of an emission test cell, it is also possible to perform non-destructive emission measurements on building products on-site in buildings. However, the procedure for such measurements is not described in this part of ISO 16000. 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[20]. An example of an emission test cell is described in Annex C of this part of ISO 16000. For the determination of formaldehyde emissions from wood-based panels, refer to EN 717-1:2004 [21] and ISO 12460-1 [1]. However, this part of ISO 16000 is also applicable to wood-based panels and other building products in order to determine the emission rate of formaldehyde. The measurement procedure for formaldehyde is described in ISO 16000-3

Introduction
The determination of volatile organic compounds (VOCs) emitted from building products using emission test
cells in conjunction with the standardised sampling, storage of samples and preparation of test specimens has
objectives such as:
⎯ to provide manufacturers, builders, and end users with emission data useful for the evaluation of the
impact of building products on the indoor air quality;
⎯ to promote the development of improved products;
⎯ on-site investigation of building product surfaces.
The method can in principle be used for most building products used indoors.

5 Principle
The principle of the test is to determine the area specific emission rates of VOCs emitted from the surface of a
product test specimen. The test is performed in an emission test cell at constant temperature, relative air
humidity, and area specific air flow rate. Measurements of the VOC concentration in the air at the outlet are
representative of the air in the emission test cell.
Area specific emission rates at a given time, t, are calculated from the emission test cell air concentrations
and the area specific air flow rate, q (see Clause 13).
With knowledge of the concentration in the air, the air flow through the emission test cell, and the surface area
of the test specimen, the area specific emission rates of VOCs from the product under test can be determined.
6 Emission test cell system
6.1 General
An emission test cell system designed and operated to determine area specific emission rates of VOCs from
building products shall contain the following: emission test cell, clean air generation and humidification
system, monitoring and control systems, to ensure that the test is carried out according to specified
[4], [5], [6], [7]
conditions .
For solid products with smooth surface, the emission test cell is placed directly against the surface of the
product test specimen. To secure air tightness, other products shall be placed in specially constructed test
specimen holders.
General specifications and requirements that apply to all types of emission test cells in this part of ISO 16000
are given in 6.2 to 6.6 below.
Quality assurance / quality control activities shall be carried out as in Annex A.
6.2 Emission test cell materials
The emission test cell and the parts of the sampling system coming in contact with the emitted VOCs (all
tubings and couplings) are normally made of surface treated (polished) stainless steel or glass. However, in all
cases the requirements in 6.3 and 6.5 shall be fulfilled.
The sealing material that links together the emission test cell and the test specimen shall be low emitting and
low adsorbing and shall not contribute to the emission test cell background concentration.
6.3 Air supply
The emission test cell shall be supplied with pure and humidified air and have a device for controlling the air
flow rate with an accuracy of ± 5 %.
6.4 Air tightness
The emission test cell shall be airtight in order to avoid uncontrolled air exchange with external air.
The emission test cell shall be operated slightly above atmospheric pressure to avoid any influence from the
laboratory atmosphere.
The emission test cell is considered sufficiently tight if the inlet and outlet air flows differ by less than 5 %.
Products with a large air permeability or irregular surface may cause leakage. According to the demand for air
tightness given above they shall therefore be placed in airtight test specimen holders.

SIST EN ISO 16000-10:2006
ISO 16000-10:2006(E)
6.5 Air sampling devices
The exhaust air (at the emission test cell outlet) shall be used for sampling. Sampling of the outlet air (e.g.
with a sampling pump) is achieved by connecting adsorbent tubes to the outlet couplings.
The sum of sampling air flows shall be smaller than 90 % of the inlet air flow to the emission test cell.
A multiport sampling manifold can provide the flexibility for duplicate air sampling. The sampling manifold shall
enter directly to the outlet air stream If a duct shall be used, it shall be as short as possible and maintained at
the same temperature as the emission test cell.
NOTE The exhaust from the emission test cell should be ducted into a fume hood, ensuring that any chemicals
emitted from the test material are isolated from the laboratory environment.
6.6 Recovery and sink effects
The recovery of a target VOC can be determined using a VOC source of known specific emission rate in the
emission test cell. The concentrations generated shall be of similar magnitude as those expected during the
emission tests of building products.
Recovery tests shall be performed in the test cell on an inert surface (glass or stainless steel), using toluene
and n-dodecane. Test cell air concentrations shall be determined at 24 h after start of the test. The mean
recovery shall be greater than 80 % for toluene and n-dodecane. The results of this recovery test shall be
reported in the test report as concentration expected versus concentration measured.
NOTE 1 Low recovery of hygroscopic VOCs may occur in humidified air.
NOTE 2 Sink effects, leaks or poor calibration can cause difficulties to meet the minimum requirements. Sink and
adsorption characteristics are very much dependent on the type of compound emitted. Additional recovery tests using
target VOCs with different molecular weight and polarity can be used to increase understanding of these effects.
7 Apparatus
The equipment necessary for carrying out an emission test are listed below.
7.1 Clean air supply, e.g. pressurised purified air or synthetic air in gas cylinders.
7.2 Emission test cell system.
7.3 Humidification system.
7.4 Air humidity and temperature monitoring systems.
7.5 Air flow meters.
7.6 Facilities for recovery testing.
7.7 Either cleaning agent for the emission test cell, or oven for heating and cleaning the emission
test cell.
8 Test conditions
8.1 Temperature and relative air humidity
Products for use in Europe shall be tested at temperature and relative air humidity 23 °C, 50 % RH during the
emission test (ISO 554). The tolerances are ± 2 °C and ± 5 % RH.

ISO 16000-10:2006(E)
For products with applications under other climatic conditions alternative temperature and air humidity
conditions may be used, preferably as specified in ISO 554.
8.2 Supply air quality and background concentration
Supply air shall not contain any VOCs at levels greater than the emission test cell background requirements.
Background concentrations shall be low enough not to interfere with the emission determinations beyond
quality assurance limits.
3
The TVOC background concentration shall be lower than 20 µg/m . The background concentration of any
3
single target VOC shall be lower than 2 µg/m .
The water used for humidification shall not contain interfering VOCs.
8.3 Air velocity
The calculated or measured air velocity over the surface of the test specimen shall be in the range of
0,003 m/s to 0,3 m/s.
NOTE The air velocity can be important for evaporative controlled emissions, e.g. from liquid products. This depends
on the substrate.
EXAMPLE Examples of air velocities are given in Annex C.
8.4 Area specific air flow rate and air change rate
The emission test cell concentration depends on the area specific air flow rate that is selected as a parameter
in designing the test conditions.
EXAMPLE Examples of area specific air flow rates are given in Annex B of this part of ISO 16000.
9 Verification of the test conditions
9.1 General
All control measures shall be traceable to a certified standard according to the quality assurance and quality
control schemes (Annex A of this part of ISO 16000).
9.2 Temperature and relative air humidity control systems
Control of temperature can be made by placing the emission test cell within a location controlled to the
required temperature.
Control of relative air humidity and temperature can be made by various systems with e.g. built-in humidity
control of the supply air.
Temperature and relative air humidity shall be measured independently of the systems for controlling the
temperature and relative air humidity.
