Test for vertical flame spread of vertically-mounted bunched wires or cables This fire propagation test is also known as the “bundle fire test” and is generally only passed iex specially developed cables and wires with highly flame-retardant insulation and sheath material.
It is irrelevant how long the cable burns before extinguishing itself. The test is deemed passed if, after the flame has been removed, the burning cable extinguishes itself and the fire damage is at least 50 mm from the upper mounting clamp. In the test, a flame is applied across the entire horizontal length of a single, cm cable for a period of 90 minutes. This test is generally only passed by cables and wires with special, flame-retardant glass or mica wrapping enclosing the individual cores as well as the entire cable bundle.

The test is deemed passed, if the cable continues to conduct electricity without shorting throughout the 90 minute flame application and for a subsequent 15 minute cooling period. The faster, easier way to work with standards. In the test, a single core or cable with a length of approx. Worldwide Standards We can source any standard from anywhere in the world.
The cable volume and time of flame application is defined by the test method, since IEC comprises four different bundle fire tests: Equipements electriques du materiel roulant.
