prEN 13169:2008 (E) 4 Foreword This document (prEN 13169:2008) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, the secretariat of which is held by DIN. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 13169:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. This document is one of a series of standards for insulation products used in buildings, but this standard may be used in other areas where appropriate. In pursuance of Resolution BT 20/1993 Revised, CEN/TC 88 have proposed defining the standards listed below as a package of documents. The package of standards comprises the following group of interrelated standards for the specifications of factory made thermal insulation products, all of which come within the scope of CEN/TC 88: EN 13162, Thermal insulation products for buildings — Factory made mineral wool (MW) products — Specification EN 13163, Thermal insulation products for buildings — Factory made products of expanded polystyrene (EPS) — Specification EN 13164, Thermal insulation products for buildings — Factory made products of extruded polystyrene foam (XPS) — Specification EN 13165, Thermal insulation products for buildings — Factory made rigid polyurethane foam (PUR) products — Specification EN 13166, Thermal insulation products for buildings — Factory made products of phenolic foam (PF) — Specification EN 13167, Thermal insulation products for buildings — Factory made cellular glass (CG) products — Specification EN 13168, Thermal insulation products for buildings — Factory made wood wool (WW) products — Specification EN 13169, Thermal insulation products for buildings — Factory made products of expanded perlite (EPB) — Specification EN 13170, Thermal insulation products for buildings — Factory made products of expanded cork (ICB) — Specification EN 13171, Thermal insulation products for buildings — Factory made wood fibre (WF) products — Specification
prEN 13169:2008 (E) 5 1 Scope This European Standard specifies the requirements for factory made products of expanded perlite, with or without facings or coatings, which are used for the thermal insulation of buildings. The products are manufactured in the form of boards or multi-layered insulation. This European Standard also covers composite insulation boards (see Annex D). This European Standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. Products covered by this European Standard are also used in prefabricated thermal insulating systems and composite panels; the performance of systems incorporating these products is not covered. This European 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 with a declared thermal resistance lower than 0,20 m2⋅K/W or a declared thermal conductivity greater than 0,070 W/(m⋅K) at 10 °C are not covered by this European Standard. This European Standard does not cover in situ insulation products and products intended to be used for the insulation of building equipment and industrial installations. This European Standard does not cover the following acoustical aspects: Acoustic absorption index and direct airborne sound insulation. 2 Normative references The following referenced documents are indispensable for the application of this document.
