Testing Procedure
- Preparation: Ensure a safe testing environment free from flammable materials. Inspect the burning tester for integrity. Prepare cable samples by cutting them to specified lengths and diameters.
- Sample Installation: Secure the cable samples vertically on the fixture of the burning tester. Adjust the burner position to an appropriate height above the cable.
- Start the Test: Ignite the burner to commence cable burning. Observe and record parameters such as burning time, burning length, smoke density, etc. Maintain a safe distance during testing to avoid injury from sparks.
- End the Test: Once the cable has burned completely or reached the predetermined time limit, turn off the burner and allow the sample to cool down. Compile test data for analysis and evaluation of the cable’s flame resistance.
This comprehensive approach ensures an in-depth assessment of electric wire and cable fire safety characteristics, contributing to improved product reliability and safety across various applications.
