Thermal insulation and light weight fill products for civil engineering applications — Factory made products of expanded polystyrene (EPS) — Specification
This European Standard specifies the requirements for factory made products of expanded polystyrene which are used for frost insulation of roads, railways, trafficked areas, light weight fill for reduction of horizontal and vertical earth pressure and other civil engineering applications.
The products are manufactured in the form of boards or blocks. The standard also covers specially cut shaped boards or blocks.
The standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
The standard does not specify the required class or level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The classes and levels required for a given application are to be found in regulations or non-conflicting standards.
For applications where thermal resistance is required, products with a declared thermal resistance lower than 0.25 m2?K/W or a declared thermal conductivity greater than 0,060 W/(m? K) are not covered by this standard. This standard does not cover in situ insulation products and products intended to be used for the insulation of buildings, of building equipment and industrial installations or products intended for acoustic insulation.

In dieser Norm beschriebene Produkte werden auch für die Wärmedämmung von Gebäuden verwendet, für die EN 13163 gilt sowie für die Wärmedämmung für die Haustechnik und betriebstechnische Anlagen, für die prEN 14309 gilt.
Diese Norm legt keine Leistungsstufen für eine vorgegebene Eigenschaft fest, die ein Produkt erreichen muss, um für einen bestimmten Anwendungsfall tauglich zu sein. Für bestimmte Anwendungen benötigte Stufen können Regelwerken oder nicht entgegenstehenden Normen entnommen werden.
Diese Norm gilt nicht für Produkte, deren Nennwert des Wärmedurchlasswiderstandes geringer ist als 0,25 m2× K/W Nennwert oder deren Nennwert der Wärmeleitfähigkeit größer ist als 0,060 W/(m×K) bei 10 °C.
Diese Norm gilt nicht für Produkte für an der Verwendungsstelle hergestellte Wärmedämmung oder Produkte, die zur Dämmung für die Haustechnik oder betriebstechnische Anlagen oder Produkte, die für die Schalldämmung bestimmt sind.

1 Scope This European Standard specifies the requirements for factory made products of expanded polystyrene which are used for frost insulation of roads, railways, trafficked areas, light weight fill for reduction of horizontal and vertical earth pressure and other civil engineering applications. The products are manufactured in the form of boards or blocks. The standard also covers specially cut shaped boards or blocks. The standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. The standard does not specify the required class or level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The classes and levels required for a given application are to be found in regulations or non-conflicting standards. For applications where thermal resistance is required, products with a declared thermal resistance lower than 0,25 m²⋅K/W or a declared thermal conductivity greater than 0,060 W/(m⋅K) are not covered by this standard. This standard does not cover in situ insulation products and products intended to be used for the insulation of buildings, of building equipment and industrial installations or products intended for acoustic insulation. 2 Normative references The following referenced documents are indispensable for the application of this document.

insulating materials and products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document 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 Directives.
For relationship with EU Directives, see informative Annex ZA, which is an integral part of this document.

Annex ZA (informative) Clauses of this European Standard addressing the provision of the EU Construction
Products Directive
This European Standard is one of a series of standards for products used for insulation in buildings, installed
equipment and in civil engineering applications.
1 Scope
This European Standard specifies the requirements for factory made products of expanded polystyrene which
are used in civil engineering applications, such as light weight fill and frost insulation. Other typical
applications are: reduction of lateral earth pressure on retaining walls and bridge abutments, redistribution of
loads on buried pipes (“imperfect ditch”), compressible inclusion on swelling soils, as dampers for reduction of
vibrations, marine floating devices etcetera. The products are manufactured in the form of boards or blocks.
The standard describes product characteristics and includes procedures for testing, evaluation of conformity,
marking and labelling.
Products covered by this standard are also used for thermal insulation of building for which EN 13163 is
applicable and for insulation of building equipment and industrial installations for which prEN 14309 is
applicable.
The standard does not specify the required class or level of a given property to be achieved by a product to
demonstrate fitness for purpose in a particular application. The classes and levels required for a given
application are to be found in regulations or non-conflicting standards.

Products with a declared thermal resistance lower than 0,25 m ·K/W or a declared thermal conductivity at
10 °C greater than 0,060 W/(m·K) are not covered by this standard.
This standard does not cover in situ insulation products and products intended to be used for the insulation of
building equipment and industrial installations or products intended for acoustic insulation.

4 Requirements
4.1 General
Product properties shall be assessed in accordance with clause 5. To comply with this standard, products
shall meet the requirements of 4.2 and the requirements of 4.3, as appropriate.
NOTE Information on additional properties is given in Annex D.
One test result for a product property is the average of the measured values on the number of test specimens
given in Table 13. Wherever limit values are used, they shall represent the value achieved by at least 90% of
the production with a confidence level of 90 %.
For mechanical properties no single measured value within the consecutive group used for obtaining the test
result, shall be more than 10% lower than of the limit value defining the level. For non mechanical properties a
deviation from the limit value may be required and where appropriate these are expressed in the text.
