AS/NZS – Classification of the Fire and Mechanical Performance of Wiring Sy

A wedge shaped indentor is forced against the cable nz and loaded until it cuts through the insulation in order to determine the ability of the cable to withstand cutting action. To pass the requirements of this test, the cable must remain operational both during the 90 minute exposure and the 15 minute cooling period.

It is designed to cover nze economic sector and virtually every activity of the humankind where technical standards may be used. Generally the level of mechanical performance 2nd numeral offered by polymeric insulated and sheathed cables is 2 moderate impact.

The cable specimen is conditioned, placed on the test apparatus anvil, and connected to the circuit integrity monitoring system. 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.

References This document may make references to other documents. The impactor which is set at the prescribed drop height, is dropped 3 times onto the specimen. Fire tests on building materials and structures – Methods for determination of the fire resistance of non-loadbearing elements of construction You may be interested in this related standard Methods for fire tests on building materials, components and structures – Simultaneous determination of ignitability, flame propagation, heat release and smoke release You may be interested in this related standard.

This level of compliance can be met by most Australian fire rated power and control cables using standard constructional parameters from the relevant build standard s. After a further 15 minutes the power is disconnected. The world’s unique cable forum. Other people who purchased this product also bought Water spray test applied.

The criteria of this test states that the weighted pH value should not be less than 4. The cable is deemed to have passed when it has been exposed to the specified level of cutting force without failure. Water Test Method After the cable specimen has passed the fire test, it is removed from the furnace and exposed to a water spray for 3 minutes. May 03, Webinar Presentation on Safely protecting the electric As tough as they get Nexans Olex Handbook.

A rating that defines the performance of a Wiring System. Within the context of these generic descriptions there is a myriad of performance tests in use around the world with which to qualify a cable to such requirements.

Level of protection against mechanical damage.

Mechanical Test Method Impact test: The letter “W” shall be applied as appropriate. After removal of the flame, the cables are wiped clean and the charring should not have exceeded 2. 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.

The cable is deemed to have passed when it has been exposed to the specified level of impact energy without failure. Training Courses Voltimum webinars Voltimum e-Training. Please Login or Register.
