EN 14318-2-2013 pdf download.Thermal insulating products for buildings – In-situ formed dispensed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam products – Part 2: Specification for the installed insulation products.
This EN 14318-2 specifies requirements for in-situ formed dispensed polyurethane foam (PUR) and polyisocyanurate (PIR) foam products when installed into cavity waUs.
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 14318, the product ct,aractenstics linked to the essential requirements of the EU Constwction 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 buiing equipment and industrial installations.
NOTE Foam products are either cafled 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 “sofl foams’ or sem.-rigid foams. This note has been induded to darify that all foams with such descriptions are covered by this standards used of the temi rigid foam.

3 Terms, definitions, symbols and abbreviations
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 9229:2007 and the following apply.
polyurethane foam PU
rigid cellular plastics insulation materials or products induding both polymer types based mainly on polyurethane (PUR) or mainly on polyisocyanurate (PIR) groups
rigid foam dispensing system
kit of constituent components which when dispensed generates the rigid polyurethane (PUR) foam or the rigid polyisocyanurate (PIR) foam charactensed by the specified properties of the foam generated
Isocyanate component
liquid isocyanate product which is one of the components of the rigid foam dispensing system
polyol component
liquid polyhydroxyl product containing an expanding agent. catalysts and other additives which is one of the components of the rigid foam dispensing system
equipment used to mix and dispense the foam
mixing ratio
proportions of the components of the rigid foam dispensing system specified by the manufacturer to be dispensed to generate the rigid polyurethane or polyisocyanurate foam
Note 1 to entry: This can be expressed either as a weight or a volume ratio or both.
process of dispensing the mixture of the components into the cavity to be insulated
Note 1 to entry: The procedure involves dispensing discrete amounts of foam system, according to the manufacturer’s technical Infomiation, so that the height of the loam in the cavity increases by a specified height each time, until it reaches the desired height.
injection hole
hole cut in the inner or outer face of a cavity through which the foam system can be dispensed into the cavity
declared installed aged thermal resistance
time average value of the thermal resistance of the installed insulation over 25 years (see 5.2).EN 14318-2-2013 pdf download.
