Monte Bianco
In the absence of specific references applicable to this type of pipe, the choice of assessment methods has focused on a standard overtly intended to the manufactures of plastics for flame spread (UL-94), drawn up by an independent body for tests security and certification in the field of electrical equipment and plastics, and regarding specific French standards as the estimation of toxicity of a gas (calculation of a smoke index which takes into account also the opacity of the emitted fumes). The parameter values obtained for the Fire 1000® pipe, combined with good characteristic properties of the base material, have sanctioned over time the success in many application contexts particularly sensitive to all aspects of security. As an example for all, today this product is widely used in numerous tunnels of the Spanish railway lines.
