Level of circuit integrity in fire condition. International Classification for Standards ICS is an international classification system for technical standards. The impactor which is set at the prescribed drop height, is dropped 3 times onto the specimen. 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.

The cable is deemed to have passed when it has been exposed to the specified level of impact energy without failure.

The most common international standard relating to fire performance referenced by specifying engineers is. To pass the requirements of this test, the cable nzd remain operational both during the 90 minute exposure and the 15 0313 cooling period. The zns 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.

Water Test Method After the cable specimen has passed the fire sa, it is removed from the furnace and exposed to a water spray for 3 minutes. The cable is deemed to have passed when the specimen aa been exposed to the test for the appropriate minimum time requested by the submitter without a failure. 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. Mechanical Test Method Impact test: After removal of the flame, the cables are wiped clean and the charring should not have exceeded 2. Fire-resistance tests of elemen AS Steel tubes and tubulars for ordinary service. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

Level of protection against mechanical damage. Intended for reference in other Standards which specify wiring systems with 30133 degree of resistance to damage from fire or mechanical impact. After 90 minutes the gas is turned off.

As tough as they get Nexans Olex Handbook. Ask an Expert Trade Talk. This level of compliance can be met by most Australian fire rated power and control cables using aw constructional parameters from the relevant build standard s.

After a further 15 minutes the power is disconnected. Prysmian explains fire ratings for cable. 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 nz requirements. Click Buy for Online Library subscription. This test is carried out in a 3m cubed enclosure where a cable sample is subjected to fire.

The cable is deemed to have passed when it has been exposed to the specified level of cutting nza without failure. A rating that defines the performance of a Wiring System. 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.

Sets out a classification scheme for wiring systems according to their resistance to the hazards of fire and mechanical damage.
