Test for vertical flame propagation for a single insulated wire or cable This flame resistance test is passed by most cables constructed of flame-retardant materials, e. Worldwide Standards We can source any standard from anywhere in the world. Electric equipment for rolling stock.
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. Download our latest brochures and flyers more.

Take the smart route to manage medical device compliance. In most cases, the flame resistance of the plastics used iev greatly enhanced by the addition of aluminium or magnesium hydroxide. 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.

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. 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.

In the test, a single core or cable with a length ief approx. Christmas opening times. The above flame resistance and fire propagation tests are often confused with one another on the basis of their very similar designations.
The cable volume and time of flame application is defined by the test method, since IEC comprises four different bundle fire tests: Regeln fuer Leistungswiderstaende in offener Bauweise. As cities turn into metropolis, the correct processing of wastewater requires careful planning.
Your basket is empty. Multiple cables are bundled or layered in lengths of approx. In the test, a flame is applied across the entire horizontal length of a single, cm cable for a period of 90 minutes. However, the test methods employed are quite different.
Regles relatives aux resistances de puissance de construction ouverte. Ice 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.
