| Résumé : |
A method has been developed to conduct fire performance evaluation test of through penetration cable fire stop. The method is based on time temperature history, exposed to a high heat source typical of building Ires. The cable fire stop was prepared with a chemical formulation developed for intumescent sealing mastic. The test provides information relating to the thermal stability of intumescent char formed on the reaction of chemicals which quickly fills the hollow spaces formed by burning insulation cables. Trapped noncombustible gases within the intumescent cellular char provides insulating abilities which protects the more deeply located cables or conductors from further radiation. Metal hydroxide releases water, which causes intensive cooling of the hot surfaces, interrupting the heat transfer process taking place through the conductor. |
