1 Scope
This European Standard specifies the requirements for products of loose-filled expanded polystyrene (EPS)
beads and bonded polystyrene beads for in-situ installation in masonry cavity walls and frame constructions.
This European Standard is a specification for the insulation products before installation. It describes the
product characteristics and includes procedures for testing, marking and labelling.
This document 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.
NOTE To avoid water penetration in masonry walls special tests adjusted to local climate might be needed.
This document does not cover factory made expanded polystyrene (EPS) insulation products or factory made
or in-situ products intended to be used for the insulation of building equipment and industrial installations.

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 document.
This document does not cover products intended for airborne sound insulation and for acoustic absorption
applications.
