Bunched Cable Test IEC 60332-3

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. Multiple cables are bundled or layered in lengths of approx. 3.5 m and vertically affixed to a ladder-like metal structure, after which a flame is applied to the lower end of the cables using a propane burner. The cable volume and time of flame application is defined by the test method.

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 2.5 m measured from the bottom cable end.

Key Highlights:

• Specially constructed chamber to dimension
• Twin Ladder
• Burners as per IEC 60332-3-10
• Mass flow controllers
• Auto Ignition
• Air Velocity System
• Automatic Ladder Loading Unloading System
