SBI EN 13501 EN 13823 Building Material Single Burning Item

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.

Standards:

• EN 13501;
• EN 13823;

Software Features:

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;

Testing results:

• Average rate of heat release[RHRav(t)]
• Total Heat Release[THR(t)]
• 1000 * [RHRav(t)/(t-300)]
• Fire Growth Rate Index[FIGRA]
• Total Heat Release[THR600s]
• Occurrence of Lateral Flame Spread
• RSPav(t)
• Total Smoke Production[TSP(t)]
• 10000 * [RSPav(t)/(t-300)]
• Smoke Growth Rate Index[SMOGRA]
• Total Smoke Production[TSP600s]
