Introduction
The determination of volatile organic compounds (VOCs) emitted from building products using emission test
chambers 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.
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 rate of VOCs emitted from building
products. The test is performed in an emission test chamber at constant temperature, relative air humidity,
and area specific air flow rate. The air in the emission test chamber is fully mixed (see 9.7), and
measurements of the VOC concentration in the air at the outlet are representative of the emission test
chamber air concentrations.
Area specific emission rates at a given time, t, are calculated from the emission test chamber 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 chamber 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 chamber system
6.1 General
A facility designed and operated to determine area specific emission rates for VOCs emitted from building
products shall contain the following: emission test chamber, clean air generation and humidification system,
air mixing system, monitoring and control systems to ensure that the test is carried out according to specified
[3], [4]
conditions .
General specifications and requirements that apply to all types of emission test chambers included in this part
of the standard are given in 6.2 to 6.6 below.
Quality assurance / quality control activities shall be carried out as described in Annex A.
A general description of an emission test chamber is given in Annex C.

---------------------- Page: 14 ----------------------
SIST EN ISO 16000-9:2006
ISO 16000-9:2006(E)
6.2 Emission test chamber materials
The emission test chamber and the parts of the sampling system coming in contact with the emitted VOCs are
normally made of surface-treated (polished) stainless steel or glass.
Other materials may be used for mixing devices, e.g. fans, and for sealing materials. These shall be low
emitting and low adsorbing and shall be tested in the test chamber to confirm that they do not contribute to the
emission test chamber background concentration.
6.3 Air supply and mixing facilities
The emission test chamber shall have facilities (e.g. electronic mass flow controller) capable of continuously
controlling the air change rate at a fixed value with an accuracy of ± 5 %.
The emission test chamber shall be designed to ensure proper mixing of the emission test chamber air. The
requirements are given in 9.6.
NOTE Fans, multi-port inlet and outlet diffusers, perforated floors and baffle plates are used to obtain adequate
mixing.
6.4 Air tightness
The emission test chamber shall be airtight in order to avoid uncontrolled air exchange with external air.
The emission test chamber shall be operated slightly above atmospheric pressure to avoid influence from the
laboratory atmosphere.
The emission test chamber is considered sufficiently airtight if at least one of the following requirements is
fulfilled:
⎯ the air leakage is less than 0,5 % of the chamber volume per minute at an overpressure of 1 000 Pa;
⎯ the air leakage is less than 5 % of the supply airflow rate.
6.5 Air sampling devices
The exhaust air (at the emission test chamber outlet) shall be used for sampling, although separate sampling
ports in the emission test chamber can be used, provided that the air sampled is equivalent to the exhaust air.
The sampler manifold should 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 chamber.
The sum of sampling air flows should be smaller than 80 % of the inlet air flow to the emission test chamber to
avoid underpressure.
A multiport sampling manifold can be used to provide flexibility for duplicate air sampling. A mixing chamber
between the emission test chamber and the manifold or between the air inlet and the emission test chamber
could be included to permit addition and mixing of internal standard gases with the emission test chamber air
stream.
The exhaust from the emission test chamber 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 chamber. The concentrations generated shall be of similar magnitude to those expected during
the emission tests of building products.
© ISO 2006 – All rights reserved 5
---------------------- Page: 15 ----------------------
SIST EN ISO 16000-9:2006
ISO 16000-9:2006(E)
Recovery tests shall be performed in the test chamber using toluene and n-dodecane. Chamber
concentrations shall be determined at 72 h after start of the test (i.e. first mandatory measurement, see 12.3).
The mean recovery shall be greater than 80 % for toluene and n-dodecane. The results of recovery test shall
be reported (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 chamber system.
7.3 Humidification system.
7.4 Air humidity, temperature and air velocity monitoring systems.
7.5 Air flow meters.
7.6 Cleaning agent for the emission test chamber walls or equipment for thermal desorption.
7.7 Equipment for measurement of air mixing.
7.8 Facilities for recovery testing.
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.
For products with applications under other climatic conditions, alternative temperature and air humidity
conditions may be used, preferably as specified in ISO 554.
Initial variance can be observed in the emission test chamber climate after opening the emission test chamber
door and loading a test specimen. These variances should be recorded.
8.2 Supply air quality and background concentration
Supply air shall not contain any VOCs at levels greater than the emission test chamber 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 .

8.3 Air velocity
The air velocity near the surface of the test specimen shall be in the range 0,1 m/s to 0,3 m/s.
NOTE 1 An averaging time of 1 min is appropriate for air velocity measurements.
NOTE 2 The air velocity can be important for evaporative controlled emissions, e.g. from some liquid products. This
depends on the substrate.
8.4 Area specific air flow rate and air change rate
The emission test chamber concentration depends on the area specific air flow rate that is selected as a
parameter in designing the emission test conditions.
