This Technical Specification (CEN/TS) was approved by CEN on 9 March 2018 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

European foreword
This document (CEN/TS 17196:2018) 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 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.
A similar standard has been developed for soil, sludge and biowaste, see Annex A.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
Introduction
Following an extended evaluation of available methods for content analysis in construction products
(CEN/TR 16045) it was concluded that multi matrix and multi-element digestion methods have
preference over methods developed for single matrices or small groups of matrices. This implies that
for inorganic substances aqua regia digestion is preferred for the digestion of construction products for
content analysis.
This document has been adopted from the work carried out in the context of CEN/TC 292 and
CEN/TC 400 and is very similar to EN 13657 Characterization of waste – Digestion for subsequent
determination of aqua regia soluble portion of elements [1] and EN 16174 Sludge, treated biowaste and
soil – Digestion of aqua regia soluble fractions of elements [2].
This Technical Specification is part of a modular horizontal approach which was adopted in
CEN/TC 351. 'Horizontal' means that the methods can be used for a wide range of materials and
products with certain properties. 'Modular' means that a test standard developed in this approach
concerns a specific step in assessing a property and not the whole chain of measurement (from
sampling to analyses). Beneficial features of this approach are that modules can be replaced by better
ones without jeopardizing the standard chain and duplication of work of in different Technical
Committees for Products can be avoided as far as possible.
The modules that relate to the standards developed in CEN/TC 351 are specified in CEN/TR 16220 [3],
which distinguishes between the modules. This Technical Specification belongs to the analytical step.
The use of modular horizontal standards implies the drawing of test schemes as well. Before executing a
test on a certain construction product to determine certain characteristics it is necessary to draw up a
protocol in which the adequate modules are selected and together form the basis for the entire test
procedure.
WARNING — Persons using this Technical Specification should be familiar with usual laboratory
practice. The reagents used in this Technical Specification are strongly corrosive and partly very
toxic. Safety precautions are absolutely necessary, not only due to the strong corrosive reagents,
but also to high temperature and high pressure.
The use of laboratory-grade microwave equipment with isolated and corrosion resistant safety
devices is required. Domestic (kitchen) type microwave ovens should not be used, as corrosion
by acid vapours may compromise the function of the safety devices and prevent the microwave
magnetron from shutting off when the door is open, which could result in operator exposure to
microwave energy.
All procedures should be performed in a fume hood or in closed force-ventilated equipment. By
the use of strong oxidising reagents, the formation of explosive organic intermediates is
possible, especially when dealing with samples with a high organic content. Do not open
pressurized vessels before they have cooled down. Avoid contact with the chemicals and the
gaseous reaction products.
IMPORTANT — It is absolutely essential that tests conducted according to this Technical
Specification be carried out by suitably trained staff.

Solutions produced by the methods are suitable for analysis by cold vapour atomic absorption
or fluorescent spectrometry (CV-AAS, CV-AFS), for mercury (Hg).
The method in this Technical Specification is applicable to construction products.
Digestion with aqua regia will not necessarily accomplish total decomposition of the sample.
The extracted analyte concentrations may not necessarily reflect the total content in the sample.
NOTE Construction products include e.g. mineral-based products (S); bituminous products (B); metals (M);
wood-based products (W); plastics and rubbers (P); sealants and adhesives (A); paints and coatings (C),
see also CEN/TR 16045.
