This European Standard shall be given the status of a national standard, ei
13、ther by publication of an identical text or by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007. This draft European Standard consists of two parts. The first part, which is the harmonised part satisfying the mandate, the CPD a
14、nd 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. Part 1 of this European Standard has been prepared under a mandate given to CEN by the European Commission
15、and the European Free Trade Association, and supports the essential requirements of EU Directives. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of Part 1 of this standard. Attention is drawn to the need to take into account any complementary member state
16、 rules (e.g. installation rules) which together with this European Standard ensures the fitness for purpose of the installed product. This European Standard is one of a series for mineral wool, expanded clay, expanded perlite, exfoliated vermiculite, polyurethane/polyisocyanurate, cellulose and urea
17、 formaldehyde in-situ formed insulation products used in buildings, but this standard can be used in other areas where appropriate. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austri
18、a, Belgium, Bulgaria, 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. BS EN 14317-2:2
19、007EN 14317-2:2007 (E) 4 1 Scope This European Standard specifies the requirements for the four types of exfoliated vermiculite products Vermiculite Aggregate (EVA), Coated Vermiculite (EVC), Hydrophobic Vermiculite (EVH) and Premixed Vermiculite (EVM), containing less than 1 % organic material as d
20、efined by Annex D of EN 14317-1:2004 for in-situ insulation of roofs, ceilings, walls and floors. This Part 2 of the standard is a specification for the installed products. This Part 2 of this standard also specifies the checks and test procedures to be used for the declaration made by the installer
21、 of the product. This European Standard does not specify the required level of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in regulations or non-conflicting standards. This European Standard does not i
22、nclude 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 European Standard does not specify performance requirements for airborne sound insu
23、lation and for acoustic absorption applications. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、K/W Rsis the specified thermal resistance m2x K/W 4 Requirements 4.1 General The installer shall use an insulation product that complies with EN 14317-1. The installer shall inspect the building in accordance with manufacturers guidelines and national regulations, in order to determine whether it is
31、 suitable for application of the product. Guidance is given in Annex A. NOTE 1 For calculating the thermal resistance of complete building elements involving the use of these products the procedures given in EN ISO 6946 can be used. NOTE 2 EN ISO 10456 describes how the design thermal conductivity i
32、s calculated from the declared thermal conductivity. 4.2 Thermal resistance 4.2.1 Required thickness The required thermal resistance is obtained using a suitable thickness of exfoliated vermiculite. The required thickness shall be calculated by the specifier before installation starts according to t
33、he formula: dr = RsD (1) BS EN 14317-2:2007EN 14317-2:2007 (E) 6 4.2.2 Declared thermal resistance The declared thermal resistance, RD, shall be calculated from the installed thickness, di, and the corresponding declared thermal conductivity value, D, where RD= di/D.4.3 Installed insulation thicknes
34、s The mean value of the installed thickness (5.1) shall not be less than the required thickness. No individual value shall be less than 80 % of the specified value. 5 In-situ measurements 5.1 Installed insulation thickness The installed insulation thickness of the insulation layer shall be measured
35、by the installer and declared. The method of verification will vary depending on the building and the method of application. Verification shall include reference to guides or level marks placed before installation and direct measurement after installation using a calibrated depth gauge. At least fiv
36、e insulation thickness measurements in different places shall be made for each 100 m2insulation area. In case of dispute, the installed insulation thickness shall be measured in accordance with EN 823:1994, Annex A, pin and plate method. 5.2 Cavity width The width of a cavity shall be measured throu
37、gh suitable holes using a calibrated depth gauge and declared as the thickness of the insulation. At least five cavity width measurements in different places shall be made for each 100 m2insulation area. The measurements will normally be carried out by the specifier, before installation starts. NOTE
38、 The total number of measurements necessary to determine the nominal cavity width should take into account the construction of the building and possible damage to any cladding. 5.3 Cavity fill The installer shall check to ensure that a cavity is full. 6 Installers declaration The specifier in conjun
39、ction with the installer shall declare to the customer that the work has been carried out in accordance with the requirements of this standard using an insulation product that complies with EN 14317-1. The installer shall declare at least the following information: trade name and designation code of
40、 the installed product; declared thermal resistance; required thickness; installed thickness; volume of insulation material used; date of installation. The installer shall also declare that the work has been carried out according to the specified procedure. BS EN 14317-2:2007EN 14317-2:2007 (E) 7 An
41、nex A (informative) Suitability of the building and the insulation product A.1 Building The installer should ensure that the roofs, ceiling, walls and floors are structurally sound and the area is suitable to contain loose fill products or receive the bonded insulation. This assessment should take i
42、nto account all aspects of the proposed installation. On ceilings and floors with a joist or beam system, the substrate should be continuous to ensure retention of loose fill insulation products. Provision should be made for attic ventilation and vapour barriers, if necessary, prior to installation
43、of the insulation product in accordance with local building regulations and practice. Where services such as pipes pass through the construction, adequate precaution should be taken to ensure that the insulation product is retained in the area to be insulated. Roof and floor surfaces should be clean
44、, dry and free of extraneous materials. A.2 Insulation product The installer should ensure that for: loose fill insulation the containers of the insulation product are checked to ensure the designation details agree with those given by the specifier; bonded insulation the designation details of the
45、insulation product and any other materials required are checked to ensure they agree with the requirements of the specifier.
