4 Foreword This document (EN 13170:2012) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, the secretariat of which is held 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of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by May 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13170:2008. 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. Compared with EN 13170:2008, the main changes are: a) better harmonisation between the individual standards of the package (EN 13162 to EN 13171) on definitions, requirements, classes and levels; b) new normative annex on multi-layered products; c) changes on some editorial and technical content and addition of information on some specific items such as for ICB; d) addition of links to EN 15715, Thermal insulation products — Instructions for mounting and fixing for reaction to fire testing — Factory made products; e) changes to Annex ZA. This standard is one of a series of standards for insulation products used in buildings, but may be used in other areas where appropriate. In pursuance of Resolution BT 20/1993 revised, CEN/TC 88 have proposed defining the standards listed below as a “package” of documents. The package of standards comprises the following group of interrelated standards for the specifications of factory made thermal insulation products, all of which come within the scope of CEN/TC 88: EN 13162, Thermal insulation products for buildings — Factory made mineral wool (MW) products — Specification EN 13163, Thermal insulation products for buildings — Factory made expanded polystyrene (EPS) products — Specification EN 13164, Thermal insulation products for buildings — Factory made extruded polystyrene foam (XPS) products — Specification EN 13165, Thermal insulation products for buildings — Factory made rigid polyurethane foam (PU) products — Specification SIST EN 13170:2013

6 1 Scope This European Standard specifies the requirements for factory made products of expanded cork, which are used for the thermal insulation of buildings. The products are made with granulated cork agglomerated without additional binders and are delivered as boards with or without facings or coatings. Products covered by this standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered. This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. This standard 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 found in regulations or non-conflicting standards. Products with a declared thermal resistance lower than 0,25 m2⋅K/W, or a declared thermal conductivity greater than 0,060 W/(m⋅K), at 10 °C, are not covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The shorter side of the sample shall not be less than 300 mm or full size of the product, whichever is the smaller. 5.2 Conditioning No special conditioning of the test specimens is needed unless otherwise specified in the test standard. In case of dispute, the test specimens shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for at least 6 h prior to testing. For FPC no special conditioning of the test specimens is needed. When cut from boards, except for 5.3.2, test specimens shall be stored in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilisation at constant weight is achieved. Stabilisation is obtained when the relative change in weight does not exceed 0,5 % between two consecutive weekly measurements. In case of dispute, the following stepwise procedure shall be carried out:  Step 1 (dry reference): The specimens are stored for 72 h at (70 ± 2) °C, in an oven ventilated with an air taken at (23 ± 2) °C and (50 ± 5) % relative humidity, and then weighed. The mass of the test specimen at step 1 is m23,dry.  Step 2 (normal reference): After conditioning according to step 1, the specimens are stored in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilisation, and then weighed. Stabilisation, by definition, takes at least six weeks with some additional time so that the relative change in moisture does not increase by more than 5 % between two consecutive weekly measurements. The mass of the test specimen at step 2 is m23,50. Moisture content, u23,50, expressed in kilogram per kilogram, shall be determined by weighing the specimens at each step with an accuracy of 0,1 g, and calculated using Formula (1): 23,drydry2350235023mmmu,,,−= (1) 5.3 Testing 5.3.1 General Table 9 gives the dimensions of the test specimens, the minimum number of measurements required to get one test result and any specific conditions which are necessary. The test may be performed on the unfaced/uncoated product, if the facing/coating is known to have no relevance to the test result. 5.3.2 Thermal resistance and thermal conductivity Thermal resistance and thermal conductivity shall be determined in accordance with EN 12667 or EN 12939 for thick products and under the following conditions: SIST EN 13170:2013
