European foreword
This document (CEN/TR 17024:2017) has been prepared by Technical Committee CEN/TC 246
“Natural stones”, the secretariat of which is held by UNI.
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.
Introduction
Product standards for natural stone are issued by the European committee for standardization and deal
with stone masonry, tiles and slabs for cladding, flooring and stairs.
Producers in countries outside the European Union might not be familiar with these product standards.
Therefore, the scope of this document is to inform and assist the user in order to provide
recommendations for the proper use of natural stone and the requirements of the product standards
regulating their being placed on the market within the countries comprising the European Union.
1 Scope
This Technical Report applies to natural stone products intended for masonry elements, wall coverings
(including tiles), internal floor and stair finishes (including tiles) and exterior floor and stair finishes
(including paving), as well as massive stone elements.
It provides guidance for the application and use of natural stone products in accordance with European
product standards.
This Technical Report does not deal with coatings or staining problems, and does not take into account
treatments that could modify the performance characteristics of the materials.
This Technical Report does not apply to agglomerated stones and aggregates.
