Cable Fire Ratings and What they Mean | Voltimum
Generally the level of mechanical performance 2nd numeral offered by polymeric insulated and sheathed cables is 2 moderate impact. The cable is deemed to have passed when it has been exposed to the specified level of impact energy without failure. In the main, these standards are referenced in relation to installations where international cable build standards such as IEC are being considered and assessment of their suitability to the building code of Australia lies with the specifying engineer.
The cable is deemed to have passed when the specimen has been exposed to the test for the appropriate minimum time requested by the submitter without a failure. Please Login or Register. Mechanical Test Method Impact test: Water spray test applied.
The world’s unique cable forum. Type tests to verify the level of protection provided by a wiring system are given.

First Test Method Cable specimens are placed in a furnace which is programmed to follow a standard time-temperature curve, in order to determine the ability of the cable to maintain circuit integrity under fire conditions.
May 03, sa, Level of protection against mechanical damage. Fire-resistance tests of elemen Ad Steel tubes and tubulars for ordinary service. Webinar Presentation on Safely protecting the electric A wedge shaped indentor is forced against the cable specimen and loaded until it cuts through the insulation in order to determine the ability of the cable to withstand cutting action.
Sets out a classification scheme for wiring systems according to their resistance to the hazards of fire and mechanical damage. The letter “W” shall be applied as appropriate.
After a further 15 minutes the power is disconnected. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

AS/NZS – Classification of the Fire and Mechanical Performance of Wiring Sy
To 301 the requirements of this test, the cable must remain operational both during the 90 minute exposure and the 15 minute cooling period. After removal of the flame, the cables are wiped clean and the charring should not have exceeded 2. References This document may make references to other documents.

The cable is deemed to have achieved the desired degree of protection when it has been exposed to the fire test for the appropriate time and has sustained the effects of the water spray. This test is carried out in a 3m cubed enclosure where a cable sample is subjected to fire.
The impactor which is set at the prescribed drop height, is dropped 3 times ax the specimen.
