EN 14964:2006 (E) 3 Foreword This document (EN 14964:2006) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by IBN/BIN. 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of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by July 2008. 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 EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard is a product specification for rigid underlays of the type defined in Clause 3 of this European Standard and commonly used in a number of applications for roofing used in buildings. Underlays of the type specified in this European Standard are deemed to be construction products in accordance with Article 1 of the Construction Products Directive (CPD). The general test method standards referred to in this product specification fall within the scope of CEN/TC 128 unless otherwise stated in this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14964:2006 (E) 4 Introduction Article 2 of the CPD requires that construction products be fit for intended use, that is to say that the products shall have the characteristics enabling the works incorporating such products to satisfy the Essential Requirements referred to in Article 3 of the CPD. The harmonized characteristics specified by this European Standard are derived from Mandate M/122 “Roof coverings, rooflights, roof windows and ancillary products”. It contains also voluntary characteristics. Annex ZA indicates which characteristics of this European Standard are harmonized. The test methods referred to in this European Standard relate to the use of rigid underlays in roofing.

1 Scope This European Standard specifies the technical requirements for factory made flat or profiled sheets (wood-based, fibre cement flat sheets or corrugated bituminous sheets or other materials which can be characterised as one of these materials) that are used as underlays in pitched roof constructions with discontinuously laid coverings (e.g. tiles, slates). This European Standard also establishes methods of inspection and testing as well as criteria for evaluation of conformity. This European Standard does not include rigid underlays which have a stiffening function or a load bearing function. 2 Normative references The following referenced documents are indispensable for the application of this document.

Rigid underlays made of other materials shall be grouped into one of the different materials (wood-based, fibre cement, corrugated bitumen sheets) and all tests shall be carried out according to the respective material group. Factory production control and verification of manufacturer's stated values shall be carried out in accordance with Annex A. 4.2 Dimensions and tolerances (dimensional variation) The tolerances on dimensions of the products described in this European Standard are to be classified as follows:  Type OL: rigid underlays laid overlapping;  Type IL: rigid underlays laid interlocking. The tolerances for wood-based panels, fibre cement flat sheets and the corrugated bitumen sheets for type OL shall comply with the relevant applicable product standards as listed in Clause 2. Dimensions and tolerances of wood-based panels shall be determined in accordance with EN 324-1 and EN 324-2.
