Foreword
This document (CEN/TR 16045:2010) 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
Under Work Item 6, Mandate M/366 describes the need for CEN standards to test the chemical content of
construction products. However, in the first meeting of CEN/BT WG 176, the predecessor to CEN/TC 351
(June 2005, Gouda, The Netherlands), it was decided that a Technical Report (TR) should be drafted first.
This TR was for administrative reasons given work item (WI) number 14. The background and guidelines
for carrying out this work are outlined in Annex A of this report:
 a wide range of methods exist, focus will be on existing documents;
 one of the criteria for the selection of standard test methods could be the information on validation;
 content determination should not be used for certification of emissions unless this is the only
practicable or legally correct solution.
It is emphasized that the focus of the CPD is on the release of dangerous substances, not on content.
Content testing may only be applied for product release/emissions certification of a material if emissions
testing is prohibitively expensive or when it is specifically required by regulation – for example in the case
of banned substances such as certain metals or asbestos.
However, content testing may be useful as a complementary quick screening method for in-house quality
control of product emissions (e.g. as a routine check of product uniformity/conformity). Content tests can
also be relevant within the scope of the continuous surveillance by the approved bodies or further testing
of samples by the manufacturer (see Annex III of the CPD).
Content testing methods may or may not be relevant to predicting the release to soil, surface and
groundwater or the emission into indoor air. However, there are precedents for content-testing-type
methods being used as a guide to release and emissions.
An example for this concept is the German "regulation" for cementitious materials in contact with drinking
water, which includes content values for some trace elements in cements as screening test (German
DVGW Worksheet W 347, [2]). These values are not a criterion for exclusion, but the meaning is that
leaching tests for trace elements on test pieces (mortar or concrete) are only necessary if the total trace
element content in the cement is above these values.
Other examples of standards committees and industries that have followed this route in relation to
compounds that could emit into indoor air include paints and varnishes (ref.: EN ISO 17895), wood-based
panels (ref.: EN 120 and EN 717-2), toy testing (ref.: EN 71-11:2005, Annex B), the car industry for
interior trim components (e.g. Method VDA 278 and similar standards) and hard disk drive manufacturers
(various company-specific test protocols for emissions from PC components). Most of these methods use
gas extraction at elevated temperatures combined with GC-MS as the analytical approach. This
methodology has the advantage that it is similar to the analytical approach used in formal emissions test
methods, which means that, in some instances, there is a degree of qualitative and quantitative
correlation between the content-type test method and reference emissions test methods. There are
however limitations. The VOC content will unlikely bear any relationship to an emission profile in the case
of composite construction products or materials in which the VOCs are encapsulated or otherwise locked-
in to the product to prevent emission. Content testing is also not relevant to assessing secondary
emissions.
Because of the similarity of the analytical methods for digests and eluates from leaching, for reasons of
completeness and efficiency (no separate report necessary) the analysis of eluates from leaching is also
covered in this Technical Report. To make a separate report would lead to an almost full duplication of
the present report. The additional benefit of addressing both aspects is the coherence that is becoming
obvious from Figure 1.
1 Scope
This Technical Report describes appropriate standard test methods for the determination of the content of
regulated dangerous substances in construction products. Because of the similarity of the analytical
methods for digests and eluates from leaching, the analysis of eluates from leaching is also covered.
This Technical Report is relevant to all substances covered by the provisions of the main body of
Mandate M/366, i.e. those included in the work programme for the emission into indoor air, and release to
surface water, ground water and soil.
The list of regulated substances provided by the Commission in document "Indicative list of regulated
dangerous substances" [1] defines the substances, for which analytical methods for content will in
principle be needed. This report will be limited to this list.
NOTE 1 Sampling for content analysis is addressed by applying the relevant product standards and or by applying
WI 00351013, Construction products ― Assessment of release of dangerous substances ― Complement to sampling
(TR 4) [7] in case the sampling protocol for technical properties does not adequately address requirements in testing
posed by the assessment of release to soil, surface and groundwater.
NOTE 2 Based on this selection of appropriate test methods from other fields, horizontal test methods for
analysing the chemical content of construction products will be developed as ENs.
NOTE 3 In Annex B a compilation is given of the content regulations for construction products for health or
environmental reasons.

2.2.6
product matrix

NOTE For construction products for example the following product matrices could be distinguished: silica-based
products, bituminous products, metals, wood-based products, plastics and rubbers, sealants and adhesives, and
paints and coatings.
3 Approach
The first question was how to group content test methods by type of target compound and sample matrix.
The separation into different matrix types is related to the nature of the matrix, the ease of size reduction,
mode of sample handling and the suitability for digestion by acids or extraction by organic solvents.
It was suggested that most construction products and materials fall into one or more of the following main
categories of product matrices:
 silica-based products (S) (includes calcerous and stony like materials);
 bituminous products (B);
 metals (M);
 wood-based products (W);
 plastics and rubbers (P);
 sealants and adhesives (A);
 paints and coatings (C).
EXAMPLES Examples of products that could fall into more than one category are:
1) structured wall paper may contain wood-based material (paper) and plastics (PVC-P foam);
2) fibre-reinforced concrete containing silica (concrete) and wood-based (wood-fibres);
3) painted steel containing metal and paint or a coating;
4) pipes made from mineral-fibre-reinforced PVC (PVC-GF) containing plastics and silica.
When the materials can be separated easily, the product may be considered as consisting of two separately
quantified constituents. When a material is made inseparable from the composite it can be regarded as one product
to be tested as a whole. In the examples above example 1) and 3) would fall in the first group and 2) and 4) in the
second group.
Similarly, the various target chemical analytes can be grouped as follows:
 volatile organics (primary interest for emissions to indoor air);
 semi- and non-volatile organics (interest for both emissions to indoor air and impact to soil and
groundwater);
 inorganic substances – Metals and salts (primarily of interest for impact to soil and groundwater).
Product matrices and groups of analytes can also be categorised according to the typical preparation and
analytical methods. These include:
 gas extraction of volatile organics from the sample matrix and analysis by GC-MS or HPLC;
 solvent extraction of organics from the sample matrix and analysis by GC-MS or HPLC;
 analysis of metals and salts almost always involves some form of matrix digestion followed by
ICP-AES or ICP-MS;
 specific procedures of sample dissolution and analysis are required for some specific inorganic
analysed items such as Cr (VI);
 other content properties such as fibres are described as a separate group.
These classifications are used to categorise the various available content test methods in the sections
that follow.
Since the methods for analysing the chemical content of digests (inorganic substances) and organic
extracts (organic substances) are not very different from the analytical methods needed for analysis of
eluates from leaching tests, it is therefore most practical to integrate a summary of possible analytical
methods for eluate analysis in the present document (see Figure 1). It must be realised, however, that
water extracts from leaching normally require an additional solvent extraction step to concentrate the
organic substances of interest for analysis. In addition, the analytical methods used for the analysis of
VOC, VVOC and SVOC are similar to the methods used for analysing organic substances in extracts. In
Figure 1 below the possible options for content analysis, digestion and extraction as well as trapping
volatiles on sorbents is schematically shown.
NOTE 1 There are many standards in the field of the metal alloy composition. In Annex C a list is given. These
standards are not considered in this report, as these methods are not focused on environmental questions, but rather
on impurities of the metal.
NOTE 2 The water quality standards for metal content determination are given in Table 14 "Analytical methods for
inorganic substances in eluates" (see 5.2).

4 Available content test methods
4.1 Introduction
The following tables of test methods are arranged following the approach outlined above.
The order of standards is EN, EN ISO, ISO, national and other documents. National and other methods
are only mentioned when there is no EN, EN ISO or ISO available.
NOTE The documents named "CSS xxxxx" have been prepared by CEN/TC 400 "Project Committee −
Horizontal standards in the fields of sludge, biowaste and soil" (formerly CEN/BT TF 151). They currently are in the
process of being transposed into EN standards.
4.2 Inorganic substances
4.2.1 Major, minor and trace elements
4.2.1.1 General
The inorganic substances comprise all major, minor and trace elements listed in the "Indicative list of
regulated dangerous substances" [1].
The methods given will generally be applicable to a wider range of inorganic substances than those listed
in the "Indicative list of regulated dangerous substances" [1]. Table 1 is a draft list of metals and their
compounds to be considered. The availability of methods for digestion and for analysis is indicated. The
methods themselves are presented in more detail in the next paragraphs. 4.2.1.2 deals with digestion
methods (Table 2); 4.2.1.3 with analytical methods (Table 3).
NOTE 1 For the analysis of inorganic substances in digests many regulations refer to the methods for the analysis
of inorganic substances in water, even though digests have a much higher ionic strength. The methods for the
analysis of inorganic substances in water are collected in 5.2.
NOTE 2 Some elements may not be relevant from a regulatory point of view, but may be very important for the
characterization of the product. Hence methods for these elements are also given in this table.
4.2.1.2 Digestion methods for major, minor and trace elements
The digestion methods for major, minor and trace elements are given in Table 2. In the table seven
different matrices are identified, for which the expected suitability of the listed method or uncertainties
therein are indicated. Explanations are given in footnotes at the bottom of the table.
Several methods developed in the environmental field are multi-element methods. So instead of listing all
elements in the table "major, minor and trace elements" is given as indication that the digestion methods
are suitable for many elements, which may not all have been analysed. Chemical forms cannot be
assessed, as the chemical form changes after relative aggressive digestions, such as aqua regia or nitric
acid digestion, e.g. Cr (VI) cannot be assessed.
Methods for separation and subsequent analysis of minor or trace substances in metals have not been
developed to address environmental concerns, but are mainly intended to measure impurities affecting
the technical quality of a material. The methods generally have a narrow scope with the exception of
EN 24242. In case of a small impurity of, for instance Ni in Zn, the main component Zn is the one to
concentrate on from an environmental perspective and the Ni is of minor importance from an
environmental perspective.

4.2.1.3 Analytical methods for major, minor and trace elements
The most common analytical methods for major, minor and trace elements are given in Table 3. Content
analysis for most inorganic substances is based on digestion in acid followed by analysis using an optical
method. Recent developments have favoured multi-element analysis techniques such as ICP (inductively
coupled plasma). For digestion, aqua regia is the most commonly applied acid mixture to extract inorganic
substances. It is not a method that will provide a true total content, as generally a full digestion of the
silicate matrix will be required for that. From an environmental perspective, however, aqua regia is more
than adequate. Only when mass balance calculations are needed possibly true total content methods
may be needed.
Methods for the analysis of substances in natural water are many, but may not be relevant for high
concentrated extracts from construction products (methods for the analysis of eluates are indicated in 5.1).
In the table seven different matrices are identified, for which the expected suitability of the listed method
or uncertainties therein are indicated. Explanations are given in footnotes at the bottom of the table.

since the anions added with the agua regia acid mixture (Cl , NO ) interfere with the analysis of anions of
interest. In Table 4 the inorganic substances to be considered according to the indicative list (N 0230) are
listed, as are the available test methods.
