1 Scope

This section GB/T 12666 applies to test single wire or cable or cables insulated cores in a vertical state with a predetermined fire Direct combustion flame retardant properties. GB/T 12666 provisions of this part of the single wire or cable vertical burning fire intermittently for test equipment and methods, and gives recommendations Performance requirements. Note. Use to delay the spread of flame and meet the requirements of this part of the wire or cable and ensure that the lack of wires and cables can prevent flame under all conditions laid Spread, therefore, the spread in some high-risk situations, such as when large cable bundles laid perpendicular to the length, but also the use of a special device to prevent. Should not be recognized To comply with this part of the cable sample specified performance requirements, this kind of cable bundles also exhibit similar properties.

3 Sample

Test specimens from the finished wire and cable or a cord, about 455mm.

4 sample processing

Before testing, samples, devices and ambient air should reach thermal equilibrium (23.0 ± 5.0) ℃ at temperature (process at least 16h), the entire test During the ambient air temperature should be stabilized at (23.0 ± 5.0) ℃.

5 Test Equipment

5.1 ignition source Ignition source shall comply with the provisions of GB 4.2.1 /Z5169.15-2001 laboratory burner, in accordance with GB /Z5169.15-2001 Approved Method 4.4 provides for burner calibration. Arbitration test, the test should be used for technical grade methane gas (purity of at least 98.0%), the nominal calorific value 37.3MJ/m3. Allowed to make Other levels of methane, natural gas, coal gas or propane, regardless of the circumstances, should be able to provide calibration gas flame. Blowtorch flame should be calibrated at least once every two weeks. Such as the use of arbitration is not a test of technical grade methane, a day before the test to deal with spray Lamp flame calibration. When filling gas tank or any gas exchange device is changed, calibration response blowtorch flame. 5.2 blowtorch base is fixed with a wedge Blowtorch base is fixed with a wedge should be able to torch base is fixed, and burner tube and the sample in the same vertical plane (see Figure 1). The wedge Sub torch lamp can be transferred from a vertical position to a vertical position and the fire position for 20 ° angle. When in position for the fire, and I flat tube
