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.

This document 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 also, in principle, be applied to aged products. The emission
data obtained can be used to calculate concentrations in a model room.
This document applies to various emission test chambers used for determination of the emission of
volatile organic compounds from building products or furnishing.
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
[1]
described in ISO 16000-6 and ISO 16017-1 .
A general description of an emission test chamber is given in Annex C.

For the determination of formaldehyde emissions from wood-based panels, refer to EN 717-1.
However, this document 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 .
Note In principle this document can be applied to the study of any gas phase emissions from building
products and furnishing.
The determination of the emission rates of cut edges is described in Annex D.

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
[5] [6]
carried out according to specified 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 and 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.
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 %.

---------------------- Page: 12 ----------------------
oSIST prEN ISO 16000-9:2023
ISO/DIS 16000-9:2022(E)
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 total sampling flows shall not exceed 80 % of the air flow rate into the chamber to avoid negative
pressure.
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.
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.
