Introduction
This European Standard was developed under the remit of Mandate M/366 'Development of horizontal
standardized assessment methods for harmonised approaches relating to dangerous substances under
the Construction Products Directive (CPD)', addressing the preparation of horizontal measurement/test
methods for the determination of emission of regulated dangerous substances from construction
products into indoor air, soil, surface water and ground water. This mandate is a complement to the
product mandates granted by the European Commission to CEN under European law for construction
products. The harmonized 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. The text of Mandate M/366 is available at www.centc351.org.
Details of relevant European or national regulations are available in the “TRIS database” [1].
This European Standard 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) and has since been expanded to include reproducibility
data from further round robin tests between different laboratories (see Annex A).
The responsibility for product specification lies with the product TCs, as described in CEN/TR 16496.
This determination of emission into indoor air is carried out on products under their intended
conditions of use. The intended use of a construction product is generally specified in the corresponding
harmonized product standard. The specific emission rates determined using this European Standard
are associated with application of the product in a defined European Reference Room under specified
climate (temperature and humidity) and ventilation conditions. Converting the test results into a
concentration in the air of the reference room is essential because it is not possible to evaluate
emissions in all possible use scenarios.
The reference room dimensions, associated 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 European Standard 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 concentrations of dangerous
substances in the air of the reference room (see Clause 7 and Clause 9). It should 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 while maintaining sufficient flexibility on chamber
dimensions to ensure representative samples of different materials can be accommodated
(see Clause 5). Clause 8 of this European Standard specifies how emitted regulated dangerous
substances should be analysed.
This European Standard also addresses separately (see Clause 11 and Annex B) indirect methods that
provide a result that is comparable or that correlates with the result of the reference method within
their specified field of application. Such methods may be easier and/or cheaper to apply. 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.
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 European Standard is not to develop a new
testing method but to combine by normative references the use of existing standards. This approach is
complemented, when necessary, with additional and/or modified requirements to ensure all
6
---------------------- Page: 8 ----------------------
SIST EN 16516:2018
EN 16516:2017 (E)
construction products are evaluated under comparable conditions as required by the horizontal
concept specified in Mandate M/366.
In summary, the horizontal test method specified in this European Standard determines the specific
emission rate of vapour phase 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 European Standard 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' concentrations.

1 Scope
This European Standard 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 very 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 (see Annex B) and on measuring very
volatile organic compounds (see Annex C).
NOTE 2 This European Standard describes the overall procedure and makes use of existing standards mainly
by normative reference, complemented when necessary with additional or modified normative requirements.

Introduction
This European Standard was developed under the remit 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 harmonized 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.
Details of relevant European or national regulations are available in the “TRIS database” [1].
This European Standard 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) and has since been expanded to include reproducibility data from further
round robin tests between different laboratories (see Annex A).
The responsibility for product specification lies 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 harmonized
product standard. The specific emission rates determined using this European Standard are associated with
application of the product in a defined European Reference Room under specified climate (temperature and
humidity) and ventilation conditions. The reference room is needed since it is not possible to evaluate
emissions in all possible use scenarios.
The reference room dimensions, associated 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 European Standard 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 concentrations of dangerous substances in the
air of the reference room (see Clause 7 and Clause 9). It should 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 while maintaining sufficient flexibility on chamber dimensions to ensure representative samples of
different materials can be accommodated (see Clause 5). Clause 8 of this European Standard specifies how
emitted regulated dangerous substances should be analysed.
This European Standard also addresses separately (see Clause 11 and Annex B) indirect methods that
provide a result that is comparable or that correlates with the result of the reference method within their
specified field of application. Such methods may be easier and/or cheaper to apply. 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 European Standard is not to develop a new testing method
but to combine by normative references the use of existing standards. This approach is complemented, when
necessary, with additional and/or modified requirements to ensure all construction products are evaluated
under comparable conditions as required by the horizontal concept specified in mandate M/366.

In summary, the horizontal test method specified in this European Standard 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 European Standard 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' concentrations.

1 Scope
This European Standard 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 (see Annex B) and on measuring very volatile
organic compounds (see Annex C).
NOTE 2 This European Standard describes the overall procedure and makes use of existing standards mainly by
normative reference, complemented when necessary with additional or modified normative requirements.
