Fire resistance

The purpose of the Fire Resistance test is to recreate the conditions to verify the ability of the cable to continue functioning correctly during the fire that involves it directly, for the necessary time for the intervention of firefighters. The insulation may be damaged, but the cable must continue to operate in accordance with the parameters prescribed by the standards. Different types of tests are foreseen depending on the reference standard IEC, BS, EN, with the addition of additional external stresses: mechanical shock, water spray, sprinkler and water jet.

In recent years, many companies have adopted these test equipment according to international standards both to test their product and therefore to guarantee the requirements required to sell in specific sectors, and through Research & Development as a strategy to achieve new goals of improvement and savings on already consolidated products and also for new types of cable.

SIF through the collaboration with the main testing and research institutes, the scrupulous analysis of the standards and the very important communication with customers to understand their needs, has been able to develop a complete range of equipment for testing in fire conditions, with particular attention to:

  • SAFETY STANDARDS
  • EASY INSTALLATION AND USE
  • COMPLIANCE WITH STANDARD IEC 60331-11, IEC60331-21, IEC60331-1, IEC60331-2, EN50200, EN50362, BS6387, BS7846, BS8434-1, BS8434-2, BS8491.

Elements which composed the system
