Compared with EN 13166:2008, 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. This includes the limiting of the use of the slicing method for ageing in Annex C to unfaced and open-faced products and the clearer definition of how the ageing techniques should be applied to various types of PF products; 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 the Annex ZA. This standard is one of a series of standards for thermal insulation products used in buildings, but this standard may be used in other areas where appropriate. In pursuance of Resolution BT20/1993 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 13166:2013

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 0,40 m2⋅K/W or a declared thermal conductivity greater than 0,050 W/(m⋅K) at 10 °C are not covered by this standard. This standard does not cover in-situ thermal insulation products, products intended to be used for the thermal insulation of building equipment and industrial installations (covered by EN 14314 [3]). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The test may be performed on un-faced product if the facing 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 measured in accordance with EN 12667 or EN 12939 for thick products under the following conditions:  at a mean temperature of (10 ± 0,3) °C;  after conditioning in accordance with 5.2;  taking into account the effect of ageing according to Annex C.

6 Designation code A designation code for the product shall be given by the manufacturer. The following shall be included except when there is no requirement for a property described in 4.3:  The phenolic foam abbreviated term PF  This document number EN 13166  Length and width tolerance Li & Wi  Thickness tolerance Ti  Dimensional stability under normal laboratory temperature and humidity conditions DS(N)  Dimensional stability at specified temperature DS(70,-)  Dimensional stability under specified temperature and humidity conditions DS(23,90) or
(DS(70,90)  Dimensional stability at –20 °C DS(T-)  Compressive strength CS(Y)i  Tensile strength perpendicular to faces TRi  Compressive creep CC(i1/i2/y)σc  Short term water absorption WSi  Long term water absorption WL(P)i  Water vapour transmission MU or Z  Apparent density AD  Closed cell content CV where “i” shall be used to indicate the relevant class or level or the declared value and for compressive creep the term “σc” shall be used to indicate the compressive stress and “y” to indicate the number of years. The designation code for a product of phenolic foam is illustrated by the following example: EXAMPLE PF — EN 13166 — T2 — DS(T+) — DS(TH) — DS(T-) — CS(Y)150 — TR50 — WS 5 — WL(P) 4 — AD40 — CV NOTE The characteristics determined in 4.2 are not included in the designation code if a limit value (threshold value) is given for the product. SIST EN 13166:2013

All characteristics defined in 4.2, and those in 4.3 if declared, shall be subject to initial type testing. ITT shall be in accordance with Annex B of this standard. For the relevant characteristics, ITT on products corresponding also to EN 14314 [3] may be used for the purpose of ITT and declaration according to this standard. 7.3 Factory production control The minimum frequencies of tests in the factory production control shall be in accordance with Annex B of this standard. When indirect testing is used, the correlation to direct testing shall be established in accordance with EN 13172. For the relevant characteristics, FPC on products corresponding also to EN 14314 [3] may be used for the purpose of FPC and declaration according to this standard providing that the relevant characteristics have been assessed using the same test methods. 8 Marking and labelling Products conforming with this standard shall be clearly marked, either on the product or on the label or on the packaging, with the following information:  product name or other identifying characteristic;  name or identifying mark and address of the manufacturer or his authorised representative;  shift or time of production and manufacturing plant or traceability code;  reaction to fire class of the product as placed on the market in accordance with 4.2.7 (RtF); SIST EN 13166:2013

Determination of the declared values of thermal resistance and thermal conductivity A.1 General It is the responsibility of the manufacturer to determine the declared values of thermal resistance and thermal conductivity. He will have to demonstrate conformity of the product to its declared values. The declared values of thermal resistance and thermal conductivity of a product are the expected values of these properties during an economi
