Resumen:
This European standard specifies requirements for in-situ formed dispensed rigid polyurethane (PUR) and rigid polyisocyanurate foam (PIR) products when installed into cavity walls. This European Standard is a specification for the rigid foam dispensing system before installation. This European Standard describes the product characteristics and includes procedures for testing, marking and labelling and the rules for evaluation of conformity. This European Standard does not specify the required levels of all properties that should be achieved by a product to demonstrate fitness for purpose in a particular end-use application. The required levels are to be found in regulations or non-conflicting standards. This European standard does not cover factory made rigid polyurethane or polyisocyanurate foam insulation products or in-situ products intended to be used for the insulation of building equipment and industrial installations. NOTE The range of properties exhibited by PUR products is very wide. The same is true for PIR products and these two ranges often overlap. Although not in every case, generally PIR products have a higher upper service temperature and can perform better in reaction to fire tests. In all cases, for both PIR and PUR products, their individual performance claimed by the manufacturer are described by the levels of properties obtained. However, there is no differentiating test available to differentiate PUR from PIR products but research is continuing to determine if such a test can be found to enable it to be introduced into the standard by amendment at a future date. Accordingly, therefore, all the declaration clauses will be completed using the term PU to include both PUR and PIR products (see 3.1.3).
