EN 13823 SBI Single Burning Items Test Apparatus

 

Introduction

The Single Burning Item (SBI), is a method of test for determining the reaction to fire behavior of building products (excluding floorings) when exposed to the thermal attack by a single burning item (a sand-box burner supplied with propane). The specimen is mounted on a trolley that is positioned in a frame beneath an exhaust system. The reaction of the specimen to the burner is monitored instrumentally and visually. Heat and smoke release rates are measured instrumentally and physical characteristics are assessed by observation.

Feature

  • The Single Burning Item (SBI) consists of a trolley, a fixed frame, a gas collecting hood, collector, J type exhaust pipe, centrifugal fan, wind speed control device, the comprehensive measurement section, gas analysis cabinet, data acquisition system;

  • ​The trolley can be installed with two vertical sample specimens. The bottom of the vertical angle is a sand box burner. The surface ignition method is adopted, and the flame detection system is equipped as a flameout protection device;

  • ​The fixed frame support the gas collecting hood. The frame is fixed with an auxiliary burner and equipped with a flame detecting system as a flameout protection device;

  • ​Stainless steel gas collector, located at the top of the fixed frame, used to collect combustion gases;

  • ​Stainless steel J type smoke exhaust pipe, the inner diameter is (315 + 5) mm with 50mm high temperature resistant mineral cotton insulation;

  • ​The smoke exhaust system shall continuously exhaust smoke at the speed of 0.50m3/s-0.65 m3/s, and be regulated by frequency conversion;

  • ​Mass flow controller is supplied with this Single burning items, the measuring range of 0g/s-2.5g/s, reading accuracy of not less than 1.5%;

  • ​Gas supply can be automatically controlled to flow rate of 647mg/s and 2000mg/s, the gas control system can guarantee the speed of gas supply in the process of test changes should not exceed 5mg/s, to ensure the heat output of 30.7 + 2kW;

  • ​The flue gas sampling system in this SBI test machine consists of an ash filter, a cold trap, two drying columns, a sampling pump and a peristaltic pump, so as to effectively make sample gas clean and dry;

  • ​Paramagnetic oxygen analyzer, measuring range of 0-25%, measuring oxygen concentration in the gas, the concentration range of 0-25%, T90<12 seconds; Non dispersive infrared CO2 analyzer: CO2:0 ~ 10%;

  • ​A pipeline with a length of 2155mm, equipped with a pressure probe, three thermocouples, a gas sampling probe, and a white light system;

  • ​Two-way probe, with the range of at least (0-100) Pa and accuracy of 2Pa inlet pressure sensor connected. The response time of the pressure sensor 90% output is at most 1s;

  • ​The light system of single burning item is incandescent type, with (2900 + 100) K color temperature,and the flexible joint is installed on the side of the exhaust pipe;

  • Silicon photodiode detector, with 0.1% linear stability;

  • The air is introduced into the side tube to maintain the cleanliness of the optical device, which can be accomplished by compressed air;

 

Software Features of EN13823 SBI Single Burning Items

 

Provide the following calibration and operation interface:

  • ​O2/CO2 analyzer calibration: O2/CO2 output noise and drift calibration

  • ​Calibration of optical systems: noise and drift calibration of smoke measurement systems

  • ​Optical system calibration: filter calibration

  • ​Air volume calibration: air volume control range calibration

  • ​Ladder calibration and heptane calibration

 

Heat output ladder calibration meet the following requirements:

  • The delay time of the O2/CO2 analyzer is not more than 30s;

  • The response time of the O2/CO2 analyzer is not more than 12s;

  • The response time of the burner switch is not more than 12s;

  • The temperature response time shall not exceed 6s;

  • The ratio Q gas 30s (T) /HRR30s (T), (T) should be continuous (100 + 5)%;

  • The difference between the average of HRR step 2 and the average of HRR step 3 is not more than 0.5kW.

 

Heptane calibration results:

  • ​The calorific value of unit mass heptane should be THR/m (4456 + 222.8) MJ/kg;
