Test principle

A sample consisting of two vertically angled vertical wings is exposed to the flame produced by the main burner at the bottom of the right angle, the flame is produced by the combustion of propane gas, the propane gas passes through the sandbox burner and produces (30.7 ± 2.0) kW of heat output The

The combustion performance of the sample was evaluated by the entire test procedure of 20 min. Performance parameters include: heat release, smoke production, flame propagation and burning dripping and particulate matter.

Prior to igniting the main burner, the heat output and smoke generation of the burner itself should be measured for a short time using the auxiliary burner remote from the sample.

Some parameters can be measured automatically, while others can be obtained by visual inspection. The smoke pipe is equipped with a sensor for measuring the temperature, light attenuation, the mole fractions of O2 and CO2. and the airflow in the pipeline. These values are automatically recorded and used to calculate the volumetric flow rate, heat release rate (HRR) and smoke rate (SPR).

The transverse propagation and burning of the flame and the particulate matter can be measured using a visual method.

Advantages of the Single Burning Item Test Apparatus for Building Materials

The Single Burning Item Test Apparatus for building products is primarily used to evaluate the combustion behavior of construction materials during the early stage of a fire. Its core advantages are reflected in the following aspects:

1. High-Fidelity Fire Simulation

The equipment uses a 31 kW propane burner with continuous ignition, which realistically reproduces a corner fire scenario. This allows the system to closely simulate real fire development conditions in buildings and accurately assess how materials respond to fire exposure in practical applications.

2. Multi-Dimensional and Precise Quantitative Evaluation

The system is capable of comprehensively measuring key fire performance indicators, such as the Fire Growth Rate Index (FIGRA) and Smoke Production Rate Index (SMOGRA). These parameters provide a scientific and quantitative basis for evaluating the combustion and smoke characteristics of building materials, enabling accurate classification and performance comparison.

3. Non-Destructive Operation with High Safety Level

Specimens are mounted on a movable trolley, making installation and operation convenient and safe. The combustion chamber is designed with explosion-proof and smoke-control features, and is equipped with a gas solenoid valve and flame-out protection system. These safety mechanisms ensure stable operation while effectively preventing fire hazards and ensuring operator safety during testing.
