Gardazil The test sample is comprise a number a test pieces of cable from the same length, each having a minimum length of 3,5 m. Test on bunched wire or cables. Code of practice for the design, installation and maintenance of fire detection and fire alarm systems in dwellings. This part of IEC specifies a method of testing a small insulated wire under the fire conditions when the method specified in IEC is not suitable because some small conductors may melt during the application of the flame. For fixed installation in dry and damp areas as well as in the ground.

IEC IEC This part of IEC specifies a method to test on a single vertical insulated wire or cable under the conditions and the requirements for compliance. The flame shall be applied continuously for the period of time corresponding to the diameter shown in the table.

The wire or cable shall pass the test in the distance between the lower edge on the top support and the onset of charring is greater than 50 mm. In addition, a failure shall be recorded if burning extends downwards to appoint greater than mm from the lower edge of the top support.

If the failure is recorded two more tests shall be carried out. If both test results in passes, the wire or cable shall be deemed to have passed the test. IEC This part of IEC specifies a method of testing a small insulated wire under the fire conditions when the method specified in IEC is not suitable because some small conductors may melt during the application of the flame.

The ignition source is a gas burner fed with propane. IEC The test sample is comprise a number a test pieces of cable from the same length, each having a minimum length of 3,5 m. After burning the maximum extend of the charred portion of test sample should not have reached a height exceeding 2,5 m above the bottom edge of the burner, neither at the front nor the rear of the ladder.

Fire Testing Reduced Fire Propagation in accordance with IEC This test is the most common one to verify the behaviour of a cables for the fire propagation. The standard is subdivided in several parts that differ one from the other for the quantity of cable to be installed, the installation mode and the flame application time. Tests on electric and optical fiber cables under fire conditions - Part Test for vertical flame spread of vertically mounted bunched wires or cables.
