European foreword
This document (EN 17196:2023) 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 European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2024, and conflicting national standards shall be
withdrawn at the latest by May 2024.
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 supersedes CEN/TS 17196:2018.
In comparison with the previous edition, the following technical modifications have been made:
— the addition of performance data and data from intercomparison validation;
— alignment of terms and definitions within the working groups of CEN/TC 351, i.e. through the revised
version of EN 16687.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye 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 and EN 16174.
This document 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, which
distinguishes between the modules. This document 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 document should be familiar with usual laboratory practice. The
reagents used in this document 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
can 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.
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.
The use of this document may involve hazardous materials, operations and equipment. This document
does not purport to address all of the safety problems associated with its use. It is the responsibility of
the user of this document to establish appropriate measures to ensure the safety and health of personnel
prior to application of the document and to fulfil statutory and regulatory requirements for this purpose.
IMPORTANT — It is absolutely essential that tests conducted according to this document be carried out
by suitably trained staff.
1 Scope
This document specifies methods for obtaining the aqua regia digestible content of construction
products. Solutions produced by this method are for analysis by inductively coupled plasma mass
spectrometry (ICP-MS) and inductively coupled spectrometry (ICP-OES) for the following 67 elements:
Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B),
cadmium (Cd), calcium (Ca), cerium (Ce), caesium (Cs), chromium (Cr), cobalt (Co), copper (Cu),
dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), gallium (Ga), germanium (Ge), gold (Au),
hafnium (Hf), holmium (Ho), indium (In), iridium (Ir), iron (Fe), lanthanum (La), lead (Pb), lithium (Li),
lutetium (Lu), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), neodymium (Nd),
nickel (Ni), palladium (Pd), phosphorus (P), platinum (Pt), potassium (K), praseodymium (Pr), rubidium
(Rb), rhenium (Re), rhodium (Rh), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon
(Si), silver (Ag), sodium (Na), strontium (Sr), sulphur (S), tellurium (Te), terbium (Tb), thallium (Tl),
thorium (Th), thulium (Tm), tin (Sn), titanium (Ti), tungsten (W), uranium (U), vanadium (V),
ytterbium (Yb), yttrium (Y), zinc (Zn), and zirconium (Zr).
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 document is applicable to construction products.
Digestion with aqua regia will not necessarily accomplish total decomposition of the sample.
The extracted analyte concentrations might 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.
