fire resistanceautomaticfor cables

The EN 50399 Test Apparatus is designed to simulate a medium scale fire test on bunched cables or fibre optic cables, where the cables are mounted on a vertical standard steel ladder and ignited using a defined ignition source to evaluate the burning behaviour and combustion performance of the cables. The test provides data on the combustion performance of the cables in the early stages of a fire, the heat release rate test reflects the risk of flame spread along the cable and the potential impact of the fire source on the adjacent area, and the smoke density test reflects the visibility of the fire area and the risk of smoke to personal safety. EN 50399 Test Apparatus consists of • Test Chamber - Inner dimension in 1,000±100(W) x 2,000±100(D) x 4,000±100(H) mm. - The inner wall of the test chamber is made of SUS316 stainless steel, 3mm thick, and the outer wall is made of metal Sprayed, filled with refractory insulation material. - Using type K thermocouple with a diameter of 1.5 mm and a temperature resistance of not less than 700 deg. - The temperature measurement resolution of 0.1 degrees, can be monitored by computer software, two thermocouples are placed above the burner for measuring the temperature inside the chamber during the EN 50399 test. • Chamber Air Supply - Used to adjust the speed of the centrifugal fan and thus control the airflow of the combustion test chamber at 8000±400L/min or 5000±500L/min. - U-shaped pipes of a length of not less than 4.5 m, including corrugated pipes of a length of not less than 2 m, and stainless steel pipes of a length of not less than 2.5 m.
