4 Foreword This document (EN 13170:2012) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by May 2013. 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 supersedes EN 13170:2008.

This standard has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This standard contains five Annexes:

1 Scope
This European Standard specifies the requirements for factory made products of expanded cork, which are
used for the thermal insulation of buildings. The products are made with granulated cork agglomerated without
additional binders and are delivered as boards without facings or coatings.
Products covered by this standard are also used in prefabricated thermal insulation systems and composite
panels; the performance of systems incorporating these products is not covered.
This standard describes product characteristics and includes procedures for testing, evaluation of conformity,
marking and labelling.
This standard does not specify the required level of a given property to be achieved by a product to
demonstrate fitness for purpose in a particular application. The levels required for a given application are to be
found in regulations or non-conflicting standards.
2
Products with a declared thermal resistance lower than 0,25 m ⋅K/W, or a declared thermal conductivity
greater than 0,060 W/(m⋅K), at 10 °C, are not covered by this European Standard.
