• Chamber Size and Capacity
  • The apparatus is available in different chamber sizes to suit various sample sizes and testing volumes. Smaller chambers may have interior dimensions of 0.3 meters x 0.3 meters x 0.3 meters, suitable for testing small specimens or individual components. Medium-sized chambers can measure 0.6 meters x 0.6 meters x 0.6 meters, providing sufficient space for testing larger samples or a batch of products. Larger chambers, with dimensions exceeding 1 meter x 1 meter x 1 meter, 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 1200°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 both slow and rapid temperature changes. For example, a slow ramp rate may be used to study the thermal degradation of a material over time, while a rapid ramp rate can mimic the sudden heat increase during a fire outbreak.
• 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 5000 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 apparatus provides detailed and accurate information about the flammability characteristics of the tested samples.
• Compliance with Key Flammability Testing Standards
  • The apparatus complies with ASTM D635, ASTM D3801, ASTM E662, ISO 4589, and ISO 5658, 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.
