BS EN 60322:2001, IEC 60322:2001
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 by specially developed cables and wires with highly flame-retardant insulation and sheath material. In the test, a flame is applied across the entire horizontal length of a single, cm cable for a period of 90 minutes.
The test is deemed passed if, after the burner has been switched off, the burning cables extinguish themselves and the fire damage does not cover more than 2. Find Similar Items This product falls into the following categories. The faster, easier way to work with standards.

It is irrelevant how long the cable burns before extinguishing itself. You may find similar items within these categories by selecting from the choices below:. Functional integrity and fire resistance of electric cables Unlike IEC and IECthis test does not assess the flame propagation but instead checks the electrical functioning of the cable in the event of a fire.
Christmas opening times. In most cases, the flame resistance of the plastics used is greatly enhanced by the addition of aluminium or magnesium hydroxide. It is impossible to say which of the four test categories poses the most difficult challenge, since there are a range of different factors to consider. Is wastewater treatment the key to a healthy urban expansion? You’re logged in as: Regeln fuer Leistungswiderstaende in offener Bauweise. The above flame resistance and fire propagation tests are often confused with one another on the basis of their very similar designations.
