E’ stato approvato il prEN 13165 "Thermal insulation products for buildings - Factory made products of rigid polyurethane foam - Specification" - Marzo 1998. Il testo è stato redatto in ambito CEN/TC 88 "Thermal insulating materials and products", con Segreteria DIN. This European Standard specifies the requirements for factory made products of polyurethane rigid foam, with or without facings or coatings and with or without integral reinforcement, which are used for the thermal insulation of buildings. The products are manufactured in the form of boards. The standard also covers multilayered products and composite insulation products, laminates and cladding panels in which polyurethane rigid foam is the main insulant. The standard describes product characteristics and includes procedures for testing, marking and labelling. Products covered by this standard are also used in prefabricated insulation systems and composite panels; the structural performance of systems incorporating these products is not covered. The standard 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. Products intended to be used for the insulation of building equipment and industrial installations are not covered by this standard. La norma comprende cinque Allegati: Annex A (normative) Determination of the declared values of thermal conductivity and thermal resistance Annex B (normative) Factory production control Annex C (normative) Determination of the aged value of thermal conductivity and thermal resistance Annex D (informative) Additional properties Annex Z (informative) Clauses of this European Standard addressing the provisions of the EU Construction Products Directive
