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

---------------------- Page: 7 ----------------------
SIST EN 16516:2018+A1:2020
EN 16516:2017+A1:2020 (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 document 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, very volatile aldehydes and ammonia.

It is based on the use of a test chamber and subsequent analysis of the organic compounds by GC-MS,

HPLC, and for ammonia, subsequent analysis by spectrophotometric methods or any equivalent

analytical methods (such as ion chromatography and ammonium specific electrode)."

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.
