15、etariat 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of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by July 2008.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
16、 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
17、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 Ar
18、ticle 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 organizat
19、ions 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, Slovaki
20、a, 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
21、 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 chara
22、cteristics of this European Standard are harmonized. The test methods referred to in this European Standard relate to the use of rigid underlays in roofing. EN 14964:2006 (E) 5 1 Scope This European Standard specifies the technical requirements for factory made flat or profiled sheets (wood-based, f
23、ibre 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 inspe
24、ction 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.
