Fire Performance Testing(AS/NZS 3013) (IEC 60331, AS/NZS 1660.5.5) (IEC 60332-3, AS/NZS 1660.5.1)(IEC 60754-1&2, AS/NZS 1660.5.3) (IEC 60134-1&2, AS/NZS 1660.5.2)AS/NZS 3013 - CLASSIFICATION OF THE FIRE AND MECHANICAL PERFORMANCE OF WIRING SYSTEM ELEMENTSThis test is conducted in three parts:FIRE TEST METHODCable specimens are placed in a furnace which is programmed to follow a standard time-temperature curve, in orderdetermined the ability of the cable to maintain circuit integrity under fire conditions. The cable is deemed to have passed whenthe specimen has been exposed to the test for the appropriate minimum time requested by the submitter without a failure.WATER TEST METHODAfter the cable specimen has passed the fire test, it is removed from the furnace and exposed to a water spray for 3 minutes.The cable is deemed to have achieved the desired degree of protection when it has been exposed to the fire test for theappropriate time and has sustained the effects of the water spray.MECHANICAL TEST METHOD1. Impact TestThe cable specimen is conditioned, placed on the test apparatus anvil, and connected to the circuit integrity monitoring system.The impactor which is set at the prescribed drop height, is dropped 3 times onto the specimen. The cable is deemed to havepassed when it has been exposed to the specified level of impact energy without failure.2. Cutting TestA wedge shaped indentor is forced against the cable specimen and loaded until it cuts through the insulation in order todetermine the ability of the cable to withstand cutting action. The cable is deemed to have passed when it has been exposedto the specified level of cutting force without failure.WS RATINGOur fire resistant cables are WS rated to AS/NZS 3013. The rating consists of the designation “WS” (Wiring System), FirstCharacteristic Numeral (4 = 90 minutes maintained circuit integrity under fire conditions; 5 = 120 minutes maintained circuitintegrity under fire conditions). Second Characteristic Numeral (1 = light level of impact protection; 2 = medium level of impactprotection). Supplementary Letter “W” means that the cable has passed the fire test and subsequent waterspray test.IEC 60332-3, AS/NZS 1660.5.1 - FLAME RETARDANT TESTThis test is conducted by placing cables together on a vertical ladder tray and thenexposing them to the flames of a ribbon burner for the appropriate time (Detailed below).After removal of the flame, the cables are wiped clean and the charring should not haveexceeded 2.5 meters.Category A:7 litres of combustible material exposed to flame for 40 minutesCategory B:3.5 litres of combustible material exposed to flame for 40 minutesCategory C:1.5 litres of combustible material exposed to flame for 20 minutesIEC 60331, AS/NZS 1660.5.5 - FIRE TESTThis test is conducted by mounting a 1200mm length of cable over a gas burner and energizing it to its rated voltage. Flamesare applied for 90 minutes at a temperature of at least 750°C. After 90 minutes the gas is turned off. After a further 15minutes the power is disconnected. To pass the requirements of this test, the cable must remain operational both during the90 minute exposure and the 15 minute cooling period.”IEC 60754-1&2, AS/NZS 1660.5.3 - ACID GAS EMISSION TESTThis test determines the amount of acid gas emitted by burning cables.IEC 61034-1&2, AS/NZS 1660.5.2 - SMOKE DENSITY TESTThis test measures the smoke emission from cables during fire.This test is carried out in a 3m cubed enclosure where a cable sample is subjected to fire. The smoke emission and densityare measured by a light beam emitted across the inside of the enclosure to a photocell, measuring the amount of luminoustransmission received.58Triangle Flexible Cables issue 13.1
Recommended Cable Drum Handling Procedures✔✘Cradle both reelflanges betweenforks.Do not lift by topflange, cable or reelwill be damaged✔✘Reels can be hoistedwith a shaft extendedthrough both flanges.Use a spreader bar toprevent bending thereel flanges andmashing the cable.✔Place spacers underthe bottom flange andbetween reels tocreate a space toinsert the forks✘Upended heavy reels willoften arrive damaged.Refuse or receivesubject to inspectionfor hidden damage.✔✘Lower reels fromtruck using hydraulicgate, hoist or fork lift,LOWER CAREFULLY.Never drop reels.✔Always load withflanges on edge andchock and blocksecurely.✘Never allow forktynes to touch cablesurface or reel wrap.issue 13.1 Triangle Flexible Cables59
