To comply with this standard, products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate. NOTE Information on additional properties is given in Annex B. One test result for a product property is the average of the measured values on the numbers of test specimens given in Table 5. 4.2 For all applications 4.2.1 Thermal conductivity For flat specimens thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 or EN 12939 for thick products. For cylindrical specimens EN ISO 8497 shall be used as specified in 5.3.2. In both cases the thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787. They shall be declared by the manufacturer according to the measuring standards mentioned above covering the product service temperature range. The following conditions apply: — the measured value shall be expressed with three significant figures; — the declared thermal conductivity curve shall be given as a limit curve, defined in EN ISO 13787; — the value of the declared thermal conductivity, D, shall be rounded upwards to the nearest 0,001 W/(m·K). SIST EN 14303:2016

EN 14303:2015 (E) 11 The declared equation/limit curve is the “declared reference” with three significant figures, that is to 0,000 1 W/(m·K) for

values below 0,1 W/(m·K) and in 0,001 W/(m·K) for

values above 0,1 W/(m·K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the equation, rounding upwards to the next 0,001 W/(m·K) has to be done for the full range of the thermal conductivity. NOTE Determinations of the declared thermal conductivity of pipe sections, following EN ISO 8497, having joints in the metering area, include the effects of these joints as defined in EN ISO 23993. 4.2.2 Dimensions and tolerances 4.2.2.1 Linear dimensions The length, l, width, b, and thickness, d, for flat products shall be determined in accordance with EN 822 and EN 823. Length, thickness and inside diameter, Di for pipe sections shall be determined in accordance with EN 13467. Thickness, d, of slabs/boards, lamella products, mats, mattresses, quilts, rolls, and wired mats shall be determined in accordance with EN 823. The load shall be as shown in Table 3. The measurements shall be done excluding the preparation of test specimens of compressed products expressed in EN 823:2013, Annex A. This preparation may be used upon request by the manufacturer. For wired mats the manufacturer may declare the thickness under loads of 50 Pa or 1 000 Pa. The thickness declaration shall be accompanied by the relevant thickness measurement load.

This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 14303:2009+A1:2013. This document is identifying those clauses of the standard which are needed for the compliance of the European Standard with the Construction Products Regulation (CPR). The main technical changes that have been made in this new edition of EN 14303 are the following: a) an addition to the foreword; b) modification to 3.2.1; c) an addition in 3.2.2; d) a new 4.3.9; e) modification of 5.3.2; f) modification of Clause 7; g) modification of Clause 8; h) modification of Annex A; i) a new Annex ZA.

For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. Locally responsible authorities and contracting entities, who are bound by EU Directives to specify their requirements using European harmonized product standards, are allowed to demand additional properties outside the provisions of this standard if this is technically necessary because of prevailing operational conditions of the building equipment or the industrial installation projected or because of safety regulations. This European Standard contains three annexes: — Annex A (normative), Factory production control; — Annex B (informative), Additional properties; — Annex ZA (informative), Clauses of this European Standard addressing the provisions of the EU Construction Products Regulation.

FprEN 14303:2015 (E) 5 This European Standard is one of a series of standards for insulation products used in building equipment and industrial installations, but this standard can 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 European package of standards, setting 21 months after availability as the date of withdrawal (dow) of national standards which conflict with the European Standards of this package. 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 14303, Thermal insulation products for building equipment and industrial installations — Factory made mineral wool (MW) products — Specification EN 14304, Thermal insulation products for building equipment and industrial installations — Factory made flexible elastomeric foam (FEF) products — Specification EN 14305, Thermal insulation products for building equipment and industrial installations — Factory made cellular glass (CG) products — Specification EN 14306, Thermal insulation products for building equipment and industrial installations — Factory made calcium silicate (CS) products — Specification EN 14307, Thermal insulation products for building equipment and industrial installations — Factory made extruded polystyrene foam (XPS) products — Specification EN 14308, Thermal insulation products for building equipment and industrial installations — Factory made rigid polyurethane foam (PUR) and polyisocyanurate foam (PIR) products — Specification EN 14309, Thermal insulation products for building equipment and industrial installations — Factory made products of expanded polystyrene (EPS) — Specification EN 14313, Thermal insulation products for building equipment and industrial installations — Factory made polyethylene foam (PEF) products — Specification EN 14314, Thermal insulation products for building equipment and industrial installations — Factory made phenolic foam (PF) products — Specification EN 15501, Thermal insulation products for building equipment and industrial installations — Factory made expanded perlite (EP) and exfoliated vermiculite (EV) products — Specification kSIST FprEN 14303:2015

FprEN 14303:2015 (E) 6 1 Scope This European Standard specifies the requirements for factory made mineral wool products, which are used for the thermal insulation of building equipment and industrial installations with an operating temperature range of approximately 0 °C to + 800 °C. Below an operating temperature of ambient, special means against water vapour diffusion and water accumulation by air flow might be required. Below an operating temperature of - 50 °C, special tests regarding the suitability of the products in the intended application are advised (e.g. liquefaction of oxygen). Manufacturer's advice should be heeded in all cases. The products are manufactured with or without facings or coatings, in the form of rolls, boards, slabs, mats, felts, quilts, wired mats, lamella mats, bevelled lags and pipe sections. This European Standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. 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 European Standard does not specify the required level of a given property that should be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application can be found in regulations and invitations to tender. Products with a declared thermal conductivity greater than 0,065 W/(m·K) at 10 °C are not covered by this standard. This European Standard does not cover products for in situ insulation (blowing or pouring) or products for the insulation of the building structure. This European Standard does not cover the following acoustical aspects: direct airborne sound insulation and impact noise transmission index. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
