The Building Material Non-Combustibility Test Furnace is equipment used to test whether building materials possess non-combustible properties. Before use, the following points should be noted:

1. Confirm the installation location: The test furnace should be placed in a ventilated, dry, and flame-free indoor environment, ensuring no flammable materials are nearby to prevent fire hazards.

2. Familiarize yourself with the furnace structure and operation methods: Before using the test furnace, thoroughly understand its structure and functions, and master the correct operating procedures to avoid accidents caused by misuse.

3. Check the electrical wiring: Before use, inspect the electrical wiring of the test furnace to ensure it is safe and reliable, with proper grounding to prevent risks such as electric leakage.

4. Preheat the test furnace: Prior to testing, preheat the furnace by turning on the heater in advance to reach the required temperature.

5. Select appropriate test parameters: Choose suitable test parameters, such as temperature and time, based on the type and specifications of the building material to ensure accurate and reliable test results.

6. Observe the test process and prioritize safety: During testing, continuously monitor the furnace’s operating status and the material’s combustion behavior, adhering to safety precautions to prevent accidents.

7. Shut down the test furnace: After testing, promptly turn off the furnace heater and allow it to cool before cleaning and maintenance.
