AS/NZS – Classification of the Fire and Mechanical Performance of Wiring System Elements This test is conducted in three parts: First Test. Download scientific diagram | Standard Time-Temperature Curve for AS/NZS from publication: CERAMIFYING INSULATION MATERIALS FOR FIRE. Austest Laboratories is pleased to announce further expansion of its capabilities to include mechanical testing of cables and wiring elements in.

A rating that defines the performance of a Wiring System. This document may make references to other documents. Follow these links to find other Standards similar to the one you are viewing. 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.

Please login or register. Mechanical Test Method Impact test: 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.

Training Courses Voltimum webinars Voltimum e-Training. 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. Please Login or Register. Water spray test applied. 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.

As tough as they get Nexans Olex Handbook. 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. The world’s unique cable forum.


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.

Generally the level of mechanical performance 2nd numeral offered by polymeric insulated and sheathed cables is 2 moderate impact. After a further 15 minutes the power is disconnected. Type tests to verify the level of protection provided by ad wiring system are given.

The most 301 international standard relating to fire performance referenced by specifying engineers is. Sets out a classification scheme for wiring systems according to their resistance to the hazards of fire and mechanical damage. After 90 minutes the gas is turned off.

AS/NZS 3013:2005

Intended for reference in other Standards which specify wiring systems with a degree of resistance to damage from fire or mechanical nnzs. 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.

Cable Fire Ratings and What they Mean | Voltimum

The letter “W” shall nza applied as appropriate. 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 test is carried out in a 3m cubed enclosure where a cable sample is subjected to fire. Webinar Presentation on Safely protecting the electric After removal of the flame, the cables are wiped clean and the charring should not have exceeded 2. The impactor which is set at the prescribed drop height, is dropped 3 times onto the specimen. All referenced documents are displayed below.


The cable specimen is conditioned, placed on 30133 test apparatus anvil, a connected to the circuit integrity monitoring system.

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. The nzzs is deemed to have passed when it has been exposed to the specified level of impact energy without failure.

Cable Fire Ratings and What they Mean

International S tandards The most common international standard relating to fire performance referenced by specifying engineers is; IEC — Tests for electric cables under zs conditions — circuit integrity Part 21 – Procedures zns requirements — cables of rated voltage up to and including 0. 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 xs fire conditions.

Level of circuit integrity in fire condition. Prysmian explains fire ratings for cable. A Title And here’s some amazing content. Level of protection against mechanical damage. International Classification for Standards ICS is an international classification system for technical standards.

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. Other people who purchased this product also bought Click Buy for Online Library subscription.

To pass the requirements of this test, the cable must remain operational both during the 90 minute exposure and the 15 minute cooling period. May 03, The criteria of ws test states that the weighted pH value should not be less than 4.
