1 Scope
This European Standard specifies requirements for in-situ formed sprayed rigid polyurethane
(PUR) and polyisocyanurate (PIR) foam products when applied to walls, ceilings, roofs,
suspended ceilings and floors.
This Part 2 of this European Standard is a specification for the installed insulation
product.
This Part 2 of this European Standard describes, when taken together with Part 1 of
EN 14315, the product characteristics that are linked to the essential requirements of the
EU Construction Products Directive. It also specifies the checks and tests to be used
for the declarations made by the installer of the product.
This European Standard does not specify the required levels of all properties to be
achieved by a product to demonstrate fitness for purpose in a particular application.
The required levels are to be found in regulations or non-conflicting standards.
This European Standard does not cover factory made rigid polyurethane (PUR) or polyisocyanurate
(PIR) foam products or in-situ products intended to be used for the insulation of
building equipment and industrial installations.
NOTE Foam products are either called flexible or rigid. The flexible products are used
in upholstery and mattresses and are characterised by their ability to deflect, support
and recover to their original thickness continually during their in-use phase. Those
that are not flexible are termed rigid and do not possess these flexible characteristics.
They are mostly used for thermal insulation purposes and vary widely in their compression
strength values. Once the cell structure is crushed in a rigid foam, it does not recover
its thickness fully. Some of these rigid foams are very low in density with very low
compression strengths and are sometimes described “commercially” as “soft foams” or
“semi-rigid” foams. This note has been included to clarify that all foams with such
descriptions are covered by this standard’s used of the term rigid foam.
