This European Stand

17、ard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2013, and conflicting national standards shall be withdrawn at the latest by July 2013. Attention is drawn to the possibility that some of the elements of this do

18、cument may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This European Standard consists of two parts which form a package. The first part is the harmonised part satisfying the mandate and the CPD and which is the bas

19、is for the CE marking covering the products, which are placed on the market. The second part, which is the non-harmonised part, covers the specification for the installed products. Both Parts need to be used for the application of the insulation products in the end-use applications covered by EN 143

20、18. Attention is drawn to the need to take into account any complementary member state rules (e.g. installation rules) which together with Part 2 of this European Standard ensures the fitness for purpose of the installed product. This European Standard is one of a series for mineral wool, expanded c

21、lay, expanded perlite, exfoliated vermiculite, polyurethane/polyisocyanurate, cellulose, bound expanded polystyrene and expanded polystyrene in-situ formed insulation products used in buildings, but this standard may be used in other areas where appropriate. The reduction in energy used and emission

22、s produced during the installed life of insulation products exceeds by far the energy used and emissions made during the production and disposal processes. This European Standard, EN 14318, Thermal insulating products for buildings In-situ formed dispensed rigid polyurethane (PUR) and polyisocyanura

23、te (PIR) foam products, consists of the following parts: Part 1: Specification for the rigid foam dispensed system before installation Part 2: Specification for the installed insulation products (the present document) According to the CEN/CENELEC Internal Regulations, the national standards organisa

24、tions of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Mal

25、ta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 14318-2:2013EN 14318-2:2013 (E) 4 1 Scope This European Standard specifies requirements for in-situ formed dispensed polyurethane foam (PUR) and polyisocyanurate (

26、PIR) foam products when installed into cavity walls. 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 characteristics linked to the essential requir

27、ements 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

28、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 equ

29、ipment 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 tha

30、t 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

31、 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 standards used of the term rigid foam. 2 Normati

43、U is Rigid PolyUrethane foam including PUR and PIR types PIR is Rigid PolyIsocyanurate Foam 4 Requirements 4.1 General The installer shall use a PUR or PIR foam system that complies with EN 14318-1. NOTE The range of properties exhibited by PUR products is very wide. The same is true for PIR product

44、s 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 th

45、e levels of properties obtained. Accordingly therefore, all the declaration clauses will be completed using the term PU to include both PUR and PIR products (see 3.1.3). 4.2 Suitability of the building for the installation of the product The installer shall inspect the building in accordance with ma

46、nufacturers technical information and any national rules, in order to determine whether it is suitable for application of the product (see Annex B). 5 In-situ measurements and calculations 5.1 Declared installed insulation thickness: Average cavity width The declared installed insulation thickness,

47、d, shall be measured in accordance with the procedure given in Annex A. However, the value shall not be less than the minimum installed insulation thickness specified by the client or given in the manufacturers technical information. 5.2 Declared installed aged thermal resistance, RDThe declared ins

48、talled aged thermal resistance RDfor the installed insulation shall be declared according to the performance chart given by the manufacturer in accordance with the procedure given in EN 14318-1. NOTE 1 The correction of the values of thermal conductivity due to the influence of moisture and temperat

49、ure can be calculated using the procedures given in EN ISO 10456. NOTE 2 For calculating the thermal resistance of complete building elements involving the use of these products the procedures given in EN ISO 6946 can be used. 5.3 Foam quality checks carried out by the installer The installer shall carry out those on site checks defined by the manufacturer, and check compliance with EN 14318-1 prior to commencing the application of the foam, generate test samples in accordance with either the procedures in Annex E of EN 14318-1:2013 and by any pr
