The fire-resistance of a product is measured by means of a furnace brought up to a temperature of more than 1000°C in accordance with a given standardised curve. The test measures the product’s capacity to conserve time through certain significant parameters.
The sound insulation of a material (for example, a panel) is given by the ability to reduce the passage of sound energy between two places.
The HIPERTEC WALL panel has been tested to UNI 140/3/78 and ISO 717/82 standards and, for the thicknesses 50 – 80 – 100 mm, obtained valuation indices of Rw = 30-30.5 dB.
Reaction to fire is the degree in which a material resists combustion. With regard to this, materials are assigned a class (0, 1, 2, 3, 4, and 5): the higher the class, the higher the degree of combustion. HIPERTEC® WALL panels, thicknesses 50 – 80 -100 mm, tested:
- At the Instituto Giordano S.p.A., pursuant to the Ministerial Decree of 26/6/84, were classified 0/1 for reaction to fire in the wall position.
- At the MPA Dresden according to EN 13823 and EN 11925-2 for reaction to fire, have been classified, according to EN 13501-1 as A2 S1 D0. Since the panel consists of two steel sheets with a layer of rockwool inbetween, the class 0 refers to the external parameter and the class 1 to the insulation. Tests have been also madeat foreign Institutes with the following results:
Germany: Panel class B1, insulation class A1 – France: class M0.
