ČSN EN 14303

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.
