Features
High Precision and Automation
Temperature Control: Precise temperature control is achieved through a PID control system, ensuring consistent testing conditions.
Data Recording: Automatically collects parameters such as temperature and time, generates dynamic curve graphs, and supports data storage and retrieval.
Automatic Ignition and Ventilation: Equipped with automatic ignition and a ventilation fan, ensuring timely removal of exhaust gases after testing and guaranteeing operational safety.
Modularity and Adaptability
Sample Support System: Adjustable support frame accommodates samples of different sizes, ensuring testing accuracy.
Multi-medium Testing: Supports the application of artificial sweat, grease, and other media to replicate complex usage environments.
Durability and Easy Maintenance
Stainless Steel Casing: High temperature resistance and corrosion resistance, suitable for long-term high-temperature testing environments.
Intuitive Operating Interface: Users can easily operate the device without complex training, and real-time data and process monitoring are provided during testing.

Test Procedures
Sample Preparation: Cut the sample to the specified dimensions (e.g., 300 mm long × 50 mm wide), and process it under specified environmental conditions, such as drying to constant weight.
Sample Installation: Suspend the sample between two flame nozzles using support rods, with the nozzles perpendicular to the sample surface. Simultaneously, suspend a specified load from the lower end of the sample.
Ignition and Temperature Measurement: Ignite the burner, using liquefied petroleum gas as the heat source. Measure the temperature using a thermocouple at a specified distance from the sample surface (e.g., 5 mm).
Temperature Control: Adjust the temperature to (800 ± 30)℃ within 3 minutes, and maintain this temperature throughout the test.
Observation and Recording: Start timing from the moment the sample is exposed to the flame until it breaks or fails. Record the time it takes for each sample to burn through, using the minimum time among five samples as the fire resistance stability of that group of samples.
