Water Test Method After the 303 specimen has passed the fire test, it is removed from the furnace and exposed to a water spray for 3 minutes.

May 03, First Test Method Cable specimens are placed in a furnace zs 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. This test is carried nzss in a 3m cubed enclosure where a cable sample is subjected to fire.

Level of circuit integrity in fire condition. Other people who purchased this product also bought 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.

International Classification for Standards ICS is an international classification system for technical standards. Mechanical Test Method Impact test: Level of protection against mechanical damage.

A rating that defines the performance of a Wiring System. All referenced documents are displayed below.

Cable Fire Ratings and What they Mean

Intended for reference in other Standards which specify wiring systems with a degree of resistance to damage from fire or mechanical impact. The cable specimen is conditioned, placed on the test apparatus anvil, and connected to the circuit integrity monitoring system.

Sets out a classification scheme for wiring systems according to their resistance to the hazards of fire and mechanical damage. As tough as they get Nexans Olex Handbook. The impactor which is set at the prescribed drop height, is 30013 3 times onto the specimen. 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. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

The smoke emission and density are measured by alight beam emitted across the inside of the enclosure to a photocell, measuring the amount of luminous transmission received.

After a further 15 minutes the power is disconnected. The cable is deemed aa 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.

A Title And here’s some amazing content. Please login or register. The criteria of this test states that the weighted pH value should nzw be less than 4. To pass the requirements of this test, the cable must remain operational both during the 90 minute exposure and the 15 minute cooling period.

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. Prysmian explains fire ratings for cable. After 90 minutes the gas is turned off. Ask an Expert Trade Talk. International S tandards The most common international standard relating to fire performance referenced by specifying engineers is; IEC — Tests for electric cables under fire conditions — circuit integrity Part 21 – Procedures and requirements — cables of rated voltage up to and including 0.
