Multiple thermocouples are strategically placed to ensure uniform temperature distribution and rapid response to any temperature fluctuations. The control panel allows for the programming of complex temperature profiles, including ramping, holding, and cycling, to mimic various real-world fire scenarios.
  • Flame Generation and Control: The flame system is highly adjustable. It can produce flames with different intensities, from a small pilot flame to a high-powered, turbulent flame. The fuel supply, which can include propane, methane, or other combustible gases, is precisely metered using high-precision flow regulators. The air-fuel ratio can be adjusted within a wide range, allowing for the customization of the flame's characteristics. This is crucial for testing the response of materials to different types of fire exposure, such as the slow-burning flames of a smoldering fire or the intense heat of a flashover.
• Advanced Instrumentation and Data Acquisition
  • The equipment is equipped with a comprehensive array of sensors and measurement devices. In addition to temperature and flame sensors, it includes optical sensors for monitoring smoke density and opacity. These sensors use light scattering or absorption techniques to accurately measure the amount and density of smoke produced. Gas sensors are incorporated to detect and analyze the composition of gases emitted during combustion, such as carbon monoxide, carbon dioxide, and volatile organic compounds. The data acquisition system is a high-speed, multi-channel device that records and stores all relevant data. It offers a sampling rate of up 8000 samples per second, ensuring that even the most transient changes in parameters are captured. The collected data can be analyzed in real-time or retrieved later for in-depth studies using specialized software, which provides detailed reports and graphical representations of the test results.
• Versatile Testing Modes and Configurations
  • The Customized Combustibility Testing Equipment offers a variety of testing modes. It can perform horizontal and vertical flame spread tests, where the behavior of a material's surface as the flame travels across it is evaluated. Cone calorimeter tests can be carried out to measure the heat release rate and other combustion parameters of a sample under a controlled radiant heat flux. Additionally, it can be configured for small-scale fire resistance tests, such as testing the integrity of a single component or a small assembly under fire conditions. The equipment can also be integrated with other environmental control systems, such as humidity and pressure control, to study the combined effects of multiple factors on combustibility.

It also meets ISO (International Organization for Standardization) standards, including ISO 5660 for reaction-to-fire tests and ISO 1716 for calorific value determination. This compliance ensures that the test results are recognized and accepted by regulatory bodies and industry peers, facilitating product certification and market access.

3. Specific Parameters

• Chamber Size and Capacity
  • The equipment is available in different chamber sizes to suit various sample sizes and testing volumes. Smaller chambers may have interior dimensions of 0.5 meters x 0.5 meters x 0.5 meters, suitable for testing small specimens or individual components. Medium-sized chambers can measure 1 meter x 1 meter x 1 meter, providing sufficient space for testing larger samples or a batch of products. Larger chambers, with dimensions exceeding 2 meters x 2 meters x 2 meters, are ideal for full-scale testing of building materials or large industrial products. The interior volume and shape are carefully designed to ensure proper air circulation and uniform exposure of the sample to the fire and environmental conditions.
• Temperature Range and Accuracy
  • As mentioned earlier, the temperature can be controlled from ambient to 1500°C, with an accuracy of ±3°C. The temperature ramp rate can be adjusted from 1°C per minute to 100°C per minute, allowing for the simulation of different fire growth rates. For example, a slow ramp rate can be used to study the thermal degradation of a material over time, while a rapid ramp rate can mimic the sudden increase in temperature during a flashover event.
• Flame Intensity and Control Parameters
  • The flame intensity can be adjusted over a wide range, with a maximum heat output equivalent to several megawatts per square meter. The fuel flow rate can be varied from a few milliliters per minute to several liters per minute, and the air-fuel ratio can be precisely controlled within a range of 1:1 to 20:1. These parameters enable the creation of flames with different characteristics, from a small, stable flame for precision testing to a large, turbulent flame for more severe fire simulations.
• Data Acquisition Rate and Resolution
  • The data acquisition system samples sensor data at a rate of 8000 samples per second. The temperature sensor has a resolution of 0.1°C, the smoke density sensor can detect changes as small as 0.01% opacity, and the gas sensors have a sensitivity in the parts per million (ppm) range for most common gases. This high-resolution and high-speed data capture ensure that the equipment provides detailed and accurate information about the combustibility characteristics of the tested samples.
• Compliance with Key Combustibility Testing Standards
  • The equipment complies with ASTM E84, ASTM E1354, ASTM E662, ISO 5660, and ISO 1716, among other relevant standards. It can also be customized to meet specific requirements of other industry standards or regulatory codes, ensuring its adaptability to different industries and applications.
