Single Burning Items

Single Burning Items, SBI, Medium scale calorimeter : Avg., max 1?, SBI-606, prEN 13823, BS EN 13823 Introduction Single Burning Items(SBI), as European's the evaluation of fire-resistance performance of building materials ,measures heat release rate(H.R.R), smoke growth rate index(SPR), oxygen consumption, CO, CO2 production, mass loss rate and so on.FESTEC's Single Burning Items test method is to measure response behavior of the product for building materials (except flooring materials) against fire when the product for building materials is exposed to heat attack(by Sand-Box burner of propane fuel) from Single Burning Items. The specimen is settled on the Trolly (moving cart) located in Frame just below the emission system. Response of specimen against burner is displayed by mechanically and visually. In mechanically, it calculates Heat Release Rate (H.R.R) and Smoke Release Rate (S.R.R), and physical properties are evaluated by visual observation. Measuring range of SBI, Fire Growth Rate Index (FIGRA) by oxygen consumption quantity of combustion products is the most representative measuring element; otherwise, representative measuring elements are oxygen consumption, CO, CO2 production, Smoke Growth Rate Index (SMOGRA) and so on. The maximum heat release rate can be measured up to 1MW. Standard prEN 13823: Reaction to fire tests for building products-Building products excluding floorings exposed to the thermal attack by a single burning item BS EN 13823: Reaction to fire tests for building products-Building products excluding floorings exposed to the thermal attack by a single burning item Features Enable to control gas flow supplied to the Burner automatically. Enable to accuracy gas flow control using MFC (Mass Flow Controller). Enable to Purge of Sampling Probe and Bi-directional Probe by compressed air of upper measuring station automatically. Auto ignition system. White Light System is following up DIN50055 is installed in Measuring Station for measuring SMOGRA Trolley with wheels; specimen can removable easily Panel for control is made up 19"analysis control rack Carousel System progresses Light Calibration automatically UK Servomex's Gas Analyzer to exactly measure O2, CO and CO2 concentrations (tolerance is within 0.02%) Specification Model FT-SBI-606 Size 3,360(W) x 3,410(D) x 4,247(H)mm Size(Control) 600(W) x 750(D) x 1800(H)mm Power AC 220V, 50/60Hz, 15A Weight Approx. 4,000kg(Chamber), Approx. 130kg(Control) Manual Supply Exhaust 0.5~0.65m3/s(measuring), Minimum. 100m3/min(extraction) Utilities Propane Gas, Heptane.
