This European Standard shall be given the status of a national standard,
28、 either by publication of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and
29、/or CENELEC shall not be held responsible for identifying any or all such patent rights. 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 D
30、irective(s), see informative Annex ZA, which is an integral part of this document. This European Standard is one of a series of standards for products used for insulation in buildings, insulation of building equipment and industrial installations and in civil engineering applications. According to t
31、he CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithua
32、nia, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 14933:2007 (E) 6 1 Scope This European Standard specifies the requirements for factory made products of expanded polystyrene which are used for frost insu
33、lation of roads, railways, trafficked areas, light weight fill for reduction of horizontal and vertical earth pressure and other civil engineering applications. The products are manufactured in the form of boards or blocks. The standard also covers specially cut shaped boards or blocks. The standard
34、 describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. The standard does not specify the required class or level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The class
35、es and levels required for a given application are to be found in regulations or non-conflicting standards. For applications where thermal resistance is required, products with a declared thermal resistance lower than 0,25 mK/W or a declared thermal conductivity greater than 0,060 W/(mK) are not cov
36、ered by this standard. This standard does not cover in situ insulation products and products intended to be used for the insulation of buildings, of building equipment and industrial installations or products intended for acoustic insulation. 2 Normative references The following referenced documents
