For example, see the note in the scope of part 1 of this standard the possibility of special water penetration tests in different Member States. Products with a declared thermal conductivity at 10 °C greater than 0,060 W/(m" K) are not covered by this standard. This European Standard does not cover factory made expanded polystyrene products in the form of mats, batts, rolls or boards. This standard does not cover products intended for airborne sound insulation and for acoustic absorption applications.
