19、ucts”, the secretariat of which is held by DIN. This European Standard 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of an identical text or by endorsement, at the latest by July 2013, and conflicting national standards shall be withdrawn at the latest by July 2013. Attenti
20、on is drawn to the possibility that some of the elements of this document 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 harm
21、onised part satisfying the mandate and the CPD and which is the basis 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 th
22、e insulation products in the end-use applications covered by EN 14320. 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. Thi
23、s European Standard is one of a series for expanded perlite, exfoliated vermiculite and polyurethane/polyisocyanurate in-situ formed insulation products used in building equipment and industrial installations, but this standard may be used in other areas where appropriate. The reduction in energy us
24、ed and emissions produced during the installed life of insulation products exceeds by far the energy used and emissions made during the production and disposal processes. EN 14320, Thermal insulating products for building equipment and industrial installations In-situ formed sprayed rigid polyuretha
25、ne (PUR) and polyisocyanurate foam (PIR) 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 n
26、ational standards organisations 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,
27、Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 14320-2:2013EN 14320-2:2013 (E) 4 1 Scope This European Standard specifies requirements for in-situ formed sprayed rigid polyurethane (PU
28、R) and polyisocyanurate (PIR) foam products for the insulation of building equipment industrial installations, for example storage vessels, pipes and ducts used for the supply of fuels, oil, other liquids, hot and cold water, air and other gases. Depending on the type of foam products complying with
29、 this standard, they may have service temperature ranges which lie within the limits of 200 C. 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 14320, the product char
30、acteristics 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 achiev
31、ed 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 (PUR) or polyisocyanurate (PIR) foam products or in-situ prod
32、ucts intended to be used for the insulation of buildings. The products are not intended for use for direct airborne sound insulation or acoustic absorption applications. NOTE Foam products are either called flexible or rigid. The flexible products are used in upholstery and mattresses and are charac
33、terised 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 co
34、mpression 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 ha
35、s been included to clarify that all foams with such descriptions are covered by this standards used of the term rigid foam. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

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, g
48、enerally 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. Accordingly, therefore, all the de
49、claration 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 equipment or industrial installation for the installation of the product The installer shall inspect the building equipment or industrial installation in accordance with manufacturers technical information and any national rules, in order to determine whether it is suitable for application of the product (see Annex E). 5 In-situ measurements and calculations 5.1 Declared installed insulation thicknes
