18、eld 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of an identical text or by endorsement, at the latest by February 2005, and conflicting national standards shall be withdrawn at the latest by February 2005. This document has been prepared und
19、er a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directives. For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document. This standard consists of two parts. The fir
20、st part, which is the harmonised part satisfying the mandate, the CPD and is the basis for the CE marking, covers the products, which are placed on the market. The second part, which is the non-harmonised part, covers the specification for the installed products. This European Standard is one of a s
21、eries for mineral wool, expanded clay, expanded perlite, exfoliated vermiculite, polyurethane/polyisocyanurate, cellulose and urea formaldehyde in-situ formed insulation products used in buildings, but this standard may be used in other areas where appropriate. According to the CEN/CENELEC Internal
22、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, Netherland
23、s, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14317-1:2004 (E) 4 1 Scope This document specifies the requirements for the four types of exfoliated vermiculite products Vermiculite Aggregate (EVA), Coated Vermiculite (EVC), Hydrophobic Vermiculite
24、(EVH) and Premixed Vermiculite (EVM), containing less than 1 % organic material as defined by Annex D for in-situ insulation of roofs, ceilings, walls and floors. This document is a specification for the insulation products before installation. This document describes the product characteristics and
25、 includes procedures for testing, evaluation of conformity, marking and labelling. This document 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 f
26、ound in regulations or non-conflicting standards. This document does not cover factory made insulation products of formed shapes and boards made with exfoliated vermiculite or in-situ products intended to be used for the insulation of building equipment and industrial installations. This document do
27、es not specify performance requirements for airborne sound insulation and for acoustic absorption applications. 2 Normative references The following referenced documents are indispensable for the application of this document.
