This Technical Specification (CEN/TS) was approved by CEN on 23 October 2022 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, 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

European foreword
This document (CEN/TS 17459:2022) 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 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 announce this Technical Specification: 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
The regulatory and technical background for this document is explained in CEN/TR 17105 [1]. General
information on ecotoxicity assessment is also provided there. This document describes the assessment
of ecotoxicological properties of eluates of construction products received from horizontal leaching tests
harmonized by CEN/TC 351.
Aquatic ecotoxicity tests can be applied to eluates of construction products which come into contact with
soil or water in their intended use as described in CEN/TR 16098:2010, 3.2.2.2 Products relevant for soil,
surface water or groundwater [3] and in CEN/TS 16637-1. The test procedure specified in this document
covers construction products defined in the scope. Validation data are provided in Annex A.
This document is recommended to Technical Committees for construction products (product TCs), if they
have been mandated to address ecotoxicity in their product standards or if they are interested to include
ecotoxicity in a dossier prepared in the context of qualifications for a “without testing” status. This
document is also recommended to EOTA in case there is a wish to include ecotoxicity testing in European
Assessment Documents.
1 Scope
1) This document specifies a test procedure that combines horizontal leaching tests with ecotoxicity
tests for the assessment of eluates of the construction products specified in this scope subjected to
wet conditions in outdoor use.
2) The method specified in this document is intended for the determination of the potential ecotoxicity
of eluates extracted out of construction products containing constitutional organic components of
main categories of product matrices P (plastics and rubbers), A (sealants and adhesives) or C (paints
and coatings) according to CEN/TR 16045.
3) Construction products mainly made of inorganic materials: main categories of product matrices S
(silica-based and calcareous products) and M (metals) according to CEN/TR 16045 are excluded,
unless:
— the liquid or paste product hardens in direct contact with soil or groundwater; and
— the used binder contains > 50 % organics by mass.
NOTE 1 This exception mainly refers to products used for soil injection and stabilization, e.g. grouts.
Also, the method is not intended for construction products made of treated or untreated solid wood
in main category of product matrix W (wood-based products) according to CEN/TR 16045. For
engineered bio-based products the test procedure can be of interest.
4) This document is not applicable for the assessment of terrestrial ecotoxicity of construction products.
NOTE 2 Terrestrial ecotoxicity tests for construction products are described in CEN/TR 17105.
