Introduction
This Technical Specification was developed in the frame of the Mandate M/366 "Development of horizontal
standardized assessment methods for harmonised approaches relating to dangerous substances under the
Construction Products Regulation (CPR)" addressing the preparation of horizontal measurement/test methods
for the determination of emission of regulated dangerous substances from construction products into indoor
air. This mandate is a complement to the product mandates granted by the European Commission to CEN
under the Construction Products Regulation. The harmonised products standards (hEN) developed in CEN
under mandates from the European Commission specify construction product(s) as put on the market and
address their intended conditions of use.
This Technical Specification has gone through a robustness validation for identifying how small changes in
specific testing parameters can influence the test result. This study also delivered data on repeatability within
one testing laboratory (see Annex A). It is planned to convert the TS into an EN standard immediately after
publication of this TS taking into account any relevant information provided during that process. This may
include data from further round robin tests.
It is vital that such information is clearly linked to a specified product in a product standard. The responsibility
of product specification is with the product TCs, as described in CEN/TR 16496. This determination of
emission into indoor air is to be carried out on products under their intended conditions of use. The intended
use of a construction product is generally specified in the corresponding harmonised product standard. The
specific emission rates determined using this Technical Specification are associated with application of the
product in a defined European Reference Room under specified climate (temperature and humidity) and
ventilation conditions. A reference room is needed since it is not possible to evaluate emissions by testing in
all possible use scenarios.
The reference room dimensions, resulting product loading factors, as well as climate and ventilation conditions
are selected to represent the general indoor environment (see Clause 4). Based on the huge amount of
available European experience, it was possible to identify one emission scenario and one reference room and
associated set of product loading factors to be used.
This Technical Specification specifies the horizontal reference method for testing the emission (release) of
dangerous substances from construction products into indoor air. This method uses a test chamber in which
emissions are generated under conditions which are kept constant during the test. These conditions are
selected so that the test results can be expressed in terms of chemical concentrations in the air of the
reference room (see Clause 7 and Clause 9). It is to be noted that the test chamber is defined in terms of
performance requirements. This responds to the requirement of Mandate M/366 for a horizontal approach but
still maintains sufficient flexibility on chamber dimensions to ensure representative samples of different
materials can be accommodated (see Clause 5). Clause 8 of this Technical Specification specifies how
emitted regulated dangerous substances should be analysed.
This Technical Specification also addresses separately (see Clause 11 and Annex B) indirect methods that
provide, within their specific field of application, a result that is comparable or that correlates with the result of
the reference method. Such methods may be easier to apply and/or be cheaper. They are in accordance with
mandate M/366 provided that their comparability or correlation to the reference test method has been
demonstrated in their specific field of application. They are especially suitable for Factory Production Control
testing (FPC).
The selection of one emission scenario and one reference room for evaluating emissions to indoor air is in
general accordance with the approach taken in existing European national regulations and voluntary schemes
relating to emissions from construction products into indoor air. It also accords with the horizontal
requirements of mandate M/366. The aim of this Technical Specification is not to develop a new testing
method but to combine by normative references the use of existing standards complemented, when
necessary, with additional and/or modified requirements so that – according to the horizontal concept
specified in mandate M/366 – construction products can be evaluated under comparable conditions with
regard to emissions into indoor air.

In summary, the horizontal test method specified in this Technical Specification determines the specific
emission rate of volatile organic compounds from a construction product into indoor air. This can be converted
into a concentration in the air of the reference room by calculation.
This Technical Specification has not been evaluated for the determination of 'steady state' concentration of
formaldehyde.
NOTE A European Standard (EN 717-1) exists for the determination of formaldehyde emissions from wood-based
panels, in terms of 'steady state' concentration.

curing time
minimal time defined necessary for curing before an emission test can be executed to perform relevant test
results
3.1.4
increment
individual portion of product collected by a single operation of a sampling device which is not tested as a
single entity, but is mixed with other increments in a composite sample
Note 1 to entry: Whenever the portion of product collected by a single operation of a sampling device is analysed
individually, the obtained product is called a sample. In such a situation, the quantity of product should fulfil both the
criteria for the size of an increment as well as for a sample.
[SOURCE: adapted from ISO 11074:2005, 4.1.8 as in CEN/TR 16220:2011, 2.4.5]
3.1.5
laboratory sample
sample or sub-sample(s) sent to or received by the laboratory
Note 1 to entry: When the laboratory sample is further prepared by mixing, drying, grinding or by combinations of
these operations, the result is the test sample. When no preparation of the laboratory sample is required, the laboratory
sample is the test sample. A test portion is removed from the test sample for the performance of the test/analysis or for the
preparation of a test specimen.
Note 2 to entry: The laboratory sample is the final sample from the point of view of sample collection but it is the initial
sample from the point of view of the laboratory.
[SOURCE: IUPAC, 2.5.5]
3.1.6
population
totality of items under consideration
Note 1 to entry: See also the term sub-population.

3.1.7
sample
portion of material selected from a larger quantity of material
Note 1 to entry: The manner of selection of the sample should be described in a sampling plan.
Note 2 to entry: The term "sample" is often accompanied by a prefix (e.g. laboratory sample, test sample, test
specimen) specifying the type of sample and/or the specific step in the sampling process to which the obtained material
relates.

3.1.9
scale
minimum quantity (mass or volume) of the product for which test results are obtained
Note 1 to entry: Information on characteristics of the product, including emission and variations therein, for a quantity
of product smaller than the defined scale, is judged to be not relevant for description of product properties, e.g. for
evaluation of emissions into indoor air.
Note 2 to entry: Sometimes this quantity is called lot or batch.
[SOURCE: CEN/TR 16220:2011, 2.4.4]
3.1.10
sub-population
defined part of the population that is targeted for the purposes of testing
Note 1 to entry: See also the term population.
EXAMPLE Consider a continuous production process that results in a specific product. The population for that
product is all the individual products produced between the moment the production process started (this may be years
ago) and the moment the production process ends (this may be years ahead). From the perspective of testing, this
definition does not provide a practical concept. Products produced in the past are no longer available for testing, while
products that might be produced in the (far) future are neither available. The term sub-population provides a workable
alternative, as the "start" and "end" of the sub-population can be defined in a practical way. For the same product, already
in production for a number of years, the sub-population might be the production of a year, the production of a month, or
what other definition is practical.

3.2.4
compound recovery
measured mass concentration of a target volatile organic compound in the air leaving the emission test
chamber during a given time period divided by the mass concentration of the same target volatile organic
compound added to the emission test chamber air in the same time period, expressed in percent
Note 1 to entry: The recovery provides information about the performance of the entire method.
[SOURCE: EN ISO 16000-9:2006, 3.9]
3.2.5
emission
liberation of chemical substances from a construction product into air
Note 1 to entry: Emission may be expressed as an emitted quantity in terms of concentrations in a defined volume of
air or in terms of emission rate per hour and per unit quantity of the construction product (i.e. per area, length, mass,
volume, unit or component).
Note 2 to entry: The terms "emission" and "release" have fundamentally the same meaning. However, by tradition, the
term "emission" is used when describing liberation of chemical substances or radiation into air and the term "release" is
used when describing the liberation of chemical substances into soil or water.

intended conditions of use
conditions that a product may experience during service life and that influence its release/emission behaviour
3.2.9
mass concentration of the compound in the reference room air
mass concentration of a specific volatile organic compound, VOCs, (or group of volatile organic compounds)
in a reference room
3.2.10

Foreword
This document (FprCEN/TS 16516:2013) has been prepared by Technical Committee CEN/TC 351
“Construction products – Assessment of release of dangerous substances”, the secretariat of which is held by
NEN.
This document is currently submitted to the Formal Vote.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
The current German regulation (2009/167/D) requires a different way of determining the sum of VOCs
(TVOCsum). In a European standard (EN), this would have been solved through an A-deviation. As Technical
Specifications (TSs) do not require the withdrawal of conflicting national documents, there is no need of an A-
deviation here. Instead, information on the German way is added to the informative Annex H with information
on national requirements.

Introduction
This Technical Specification is dedicated to the execution of the part of Mandate M/366 "Development of
horizontal standardized assessment methods for harmonised approaches relating to dangerous substances
under the Construction Products Regulation (CPR)" addressing the preparation of horizontal
measurement/test methods for the determination of emission of regulated dangerous substances from
construction products into indoor air. This mandate is a complement to the product mandates granted by the
European Commission to CEN under the Construction Products Regulation. The harmonised products
standards (hEN) developed in CEN under mandates from the European Commission, and EADs developed in
EOTA/OTAB for products or kits, specify construction product(s) as put on the market and address their
intended conditions of use.
This Technical Specification has gone through a robustness validation for identifying how small changes in
specific testing parameters can influence the test result. This study delivered also data on repeatability within
one testing laboratory (see Annex A). After performing round-robin tests with different construction products,
including a significant number of testing laboratories, this Technical Specification is planned to be transformed
into a European Standard (EN) after any necessary adaptations.
The information produced by applying this Technical Specification is to be used for CE marking and
Assessment and Verification of Constancy of Performance. It is vital that such information is clearly linked to a
specified product in a hEN or EAD. The responsibility of product specification is with the product TCs, as
described in FprCEN/TR 16496. This determination of emission into indoor air is to be carried out on products
under their intended conditions of use. The intended use of a construction product is generally specified in the
corresponding harmonised product standard (hEN) or EAD. The specific emission rates determined using this
Technical Specification are associated with application of the product in a defined European Reference Room
under specified climate (temperature and humidity) and ventilation conditions. A reference room is needed
since it is not possible to evaluate emissions by testing in all possible use scenarios.
The reference room dimensions, resulting product loading factors, and climate and ventilation conditions are
selected to represent the general indoor environment (see Clause 4). Based on the huge amount of available
European experience, it was possible to identify one emission scenario and one reference room and
associated set of product loading factors to be used.
This Technical Specification specifies the horizontal reference method for testing the emission (release) of
dangerous substances from construction products into indoor air. This method uses a test chamber in which
emissions are generated under conditions which are kept constant during the test. These conditions are
selected so that the test results can be expressed in terms of chemical concentrations in the air of the
reference room (see Clauses 7 and 9). It is to be noted that the test chamber is defined in terms of
performance requirements. This responds to the requirement of Mandate M/366 for a horizontal approach but
still maintains sufficient flexibility on chamber dimensions to ensure representative samples of different
materials can be accommodated (see Clause 5). Clause 8 of this Technical Specification specifies how
emitted regulated dangerous substances should be analysed.
This Technical Specification also addresses separately (see Clause 11 and Annex B) indirect methods that
provide, within their specific field of application, a result that is comparable or that correlates with the result of
the reference method. Such methods may be easier to apply and/or be cheaper. They are in accordance with
mandate M/366 provided that their comparability or correlation to the reference test method has been
demonstrated in their specific field of application. They are especially suitable for Factory Production Control
testing (FPC).
The selection of one emission scenario and one reference room for evaluating emissions to indoor air is in
general accordance with the approach taken in existing European national regulations and voluntary schemes
relating to emissions from construction products into indoor air. It also accords with the horizontal
requirements of mandate M/366. The aim of this Technical Specification is not to develop a new testing
method but to combine by normative references the use of existing standards complemented, when

necessary, with additional and/or modified requirements so that – according to the horizontal concept
specified in mandate M/366 – construction products can be evaluated under comparable conditions with
regard to emissions into indoor air.
In summary the horizontal test method specified in this Technical Specification determines the specific
emission rate of volatile organic compounds from a construction product into indoor air. This can be converted
into a concentration in the air of the reference room by calculation.
This Technical Specification has not been evaluated for the determination of 'steady state' concentration of
formaldehyde.
NOTE A European Standard (EN 717-1) exists for the determination of formaldehyde emissions from wood-based
panels, in terms of 'steady state' concentration.

1 Scope
This Technical Specification specifies a horizontal reference method for the determination of emissions of
regulated dangerous substances from construction products into indoor air. This method is applicable to
volatile organic compounds, semi-volatile organic compounds, and volatile aldehydes. It is based on the use
of a test chamber and subsequent analysis of the organic compounds by GC-MS or HPLC.
NOTE 1 Supplemental information is given on indirect test methods (Annex B) and on measuring very volatile organic
compounds (see informative Annex C).
NOTE 2 This Technical Specification describes the overall procedure and makes use of existing standards mainly by
normative reference, complemented when necessary with additional or modified normative requirements.
This Technical Specification is mainly aimed at determining the emission performance of construction
products, when this is required under national provisions covered by the CPR (Regulation (EU)
No. 305/2011).

average sample, aggregated sample
sample that consists of two or more increments, put together in appropriate portions, from which the mean
value of a desired characteristic may be obtained
[SOURCE: adapted from ISO 11074:2005]
3.1.2

3.1.3
curing time
minimal time defined necessary for curing before an emission test can be executed to perform relevant test
results
3.1.4
increment
individual portion of product collected by a single operation of a sampling device which is not tested as a
single entity, but is mixed with other increments in a composite sample
[SOURCE: adapted from ISO 11074:2005 as in CEN/TR 16220:2011]
Note 1 to entry: Whenever the portion of product collected by a single operation of a sampling device is analysed
individually, the obtained product is called a sample. In such a situation the quantity of product should fulfil both the criteria
for the size of an increment as well as for a sample.
3.1.5
laboratory sample
sample or sub-sample(s) sent to or received by the laboratory
[SOURCE: IUPAC, 2.5.5]
Note 1 to entry: When the laboratory sample is further prepared by mixing, drying, grinding or by combinations of
these operations, the result is the test sample. When no preparation of the laboratory sample is required, the laboratory
sample is the test sample. A test portion is removed from the test sample for the performance of the test/analysis or for the
preparation of a test specimen.
Note 2 to entry: The laboratory sample is the final sample from the point of view of sample collection but it is the initial
sample from the point of view of the laboratory.
3.1.6
population
totality of items under consideration
[SOURCE: adapted from ISO 11074:2005 as in CEN/TR 16220:2011]
Note 1 to entry: See also the term sub-population.
3.1.7
sample
portion of material selected from a larger quantity of material
[SOURCE: IUPAC, 2.1.1]
Note 1 to entry: The manner of selection of the sample should be described in a sampling plan.
Note 2 to entry: The term "sample" is often accompanied by a prefix (e.g. laboratory sample, test sample, test
specimen) specifying the type of sample and/or the specific step in the sampling process to which the obtained material
relates.
3.1.8
sampling plan
predetermined procedure for the selection, withdrawal, preservation and transportation of product samples
[SOURCE: CEN/TR 16220:2011]
3.1.9
scale
minimum quantity (mass or volume) of the product for which test results are obtained

[SOURCE: CEN/TR 16220:2011]
Note 1 to entry: Information on characteristics of the product, including emission and variations therein, for a quantity
of product smaller than the defined scale, is judged to be not relevant for description of product properties, e.g. for
evaluation of emissions into indoor air .
3.1.10
sub-population
defined part of the population that is targeted for the purposes of testing
[SOURCE: adapted from ISO 11074:2005 as in CEN/TR 16220:2011]
Note 1 to entry: See also the term population.
EXAMPLE Consider a continuous production process that results in a specific product. The population for that
product is all the individual products produced between the moment the production process started (this may be years
ago) and the moment the production process ends (this may be years ahead). From the perspective of testing, this
definition does not provide a practical concept. Products produced in the past are no longer available for testing, while
products that might be produced in the (far) future are neither available. The term sub-population provides a workable
alternative, as the "start" and "end" of the sub-population can be defined in a practical way. For the same product, already
in production for a number of years, the sub-population might be the production of a year, the production of a month, or
what other definition is practical.

Note 1 to entry: Emission may be expressed as an emitted quantity in terms of concentrations in a defined volume of
air or in terms of emission rate per hour and per unit quantity of the construction product (i.e. per area, length, mass,
volume, unit or component).
Note 2 to entry: The terms "emission" and "release" have fundamentally the same meaning. However, by tradition, the
term "emission" is used when describing liberation of chemical substances or radiation into air and the term "release" is
used when describing the liberation of chemical substances into soil or water.
3.2.6
emission test chamber
enclosure with controlled operational parameters for the determination of volatile organic compounds emitted
from construction products
[SOURCE: adapted from EN ISO 16000-9:2006, 3.6]

3.2.8
intended conditions of use
conditions that a product may experience during service life and that influence its release/emission behaviour
Note 1 to entry: These conditions are expressed in parameters such as temperature, amount of water during
exposure, wetting/drying; intended conditions of use may vary for instance as a function of time, location, orientation,
geographical location, etc. For simplification intended conditions of use are transferred into release scenarios for test
purposes.
3.2.9
mass concentration of the compound in the reference room air
mass concentration of a specific volatile organic compound, VOCs, (or group of volatile organic compounds)
in a reference room
3.2.10
