This European Standard is one of a series for mineral wool, expanded clay, expanded perlite, exfoliated vermiculite, polyurethane/polyisocyanurate, cellulose, bound expanded polystyrene and expanded polystyrene in-situ formed insulation products used in buildings, but this standard may be used in other areas where appropriate. The reduction in energy used and emissions produced during the installed life of insulation products exceeds by far the energy used and emissions made during the production and disposal processes. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

4.1 General Product properties shall be tested in accordance with Clause 5. To conform to this standard, products shall meet the requirements of 4.2 and 4.3 as appropriate. This European Standard gives an example of a manufacturer’s performance chart (declared thermal resistance related to the declared density range) which can be adapted for any application, see Annex K. NOTE Different applications can require different classes for settlement. One test result of a product property is the average of the measured values on the number of test specimens given in Table 6. 4.2 For all applications

The thermal values shall be determined in accordance with Annex A, 5.1 and 5.3.2 and declared by the manufacturer, according to the following:  the reference mean temperature shall be 10 °C;  the values shall be measured in dry conditions but the values declared shall be given for the product when conditioned at 23 °C and a relative humidity of 50 % (see 5.2);  the thermal resistance, RD, shall always be declared. The thermal conductivity, D, shall be declared where possible;  the thermal resistance, RD, and the thermal conductivity, D, shall be given as limit values representing at least 90 % of the production determined with a confidence level of 90 %;  the measured values shall be expressed to three significant figures;  the declared thermal resistance, RD, shall be calculated from the declared thermal insulation thickness and the corresponding D, taking into account the declared settlement sD (see NOTE below);

NOTE
The thermal resistance for loose-fill cellulose insulation is declared by the manufacturer in accordance with the declared density range using thermal conductivity measurements taken at densities across the declared density range and the worst result used as the declared value (see Annex K).
