IEC 60332-3C PDF
Burning Behaviour of Bunched Cables. IEC The European Commission and The European Cable Industry (EUROPACABLE) are finalising. Definitions. IEC refers to various definitions, together with the following during the standard: .. F – B F. Category C, designation F – 3C F. IECC describes a method of type approval testing to define the ability of bunched cables to resist fire propagation. In this test, a cable specimen.

Due to relative low cost, fire retardant cable s are widely used as fire survival cables. This temperature is defined as temperature index. This test does not look at the smoke density or toxicity. This specifies a test for determination of smoke density.
This specifies a test for determination of the amount of halogen acid gas, other than the hydrofluoric acidevolve d during combustion of compound based on halogenated polymers and compounds containing halogenated additives taken from cable constructions. The higher the toxicity index, the more toxic the cable material is.
Wide ladder mmwide: The lowhalogen content and low corrosivity of low smoke fume cables lies somewhat in between fire retardant cable s and LSZH cables. Conquered the Summit of London.
A 1 metre cable sample is placed in the centre of the enclosure and is applied with a fire. This test details a method of test for the assessment of the flame propagation characteristics of a single wire or cable.
System 6 UTP LSOH Cable (IEC C) – International
The test method is not suitable for the testing of some small wires due to the melting of the conductors during the time of application of the flame. Cable samples on a horizontal tray in a tunnel type of chamber are burned at This test specifies a eic for the determination of degree of acidity of gases evolved during combustion of cables taken from the cable sample by measuring its pH and conductivity.
LSZH cables are not only characterized by its fire retardant performance but also by its halogen free properties, thus offering low corrosivity and toxicity.
Four survival categories are defined: The result is expressed as percentage of light transmitted. IEC and IEC are used to assess the flame propagation characteristics of a single wire.
Burning Behaviour of Bunched Cables
Home Product Dispaly Navigation. Carbon Dioxide Analyser infrared for use in heat release measurement. The cable is defined as fire resisting ifunder the conditions of this test, it being assumed that the test jec intensity is of sufficient magnitude to destroy the organic material, no failure of any of the 3A fuses occurs and if the withstand voltage on iiec is not less than the rated voltage of the cable.
The cables will be tested under the following temperatures: There are four primary fire testing standards as follows:. Method A and B. Therefore, to control the heat release is the most important concern for reducing the fire hazard.
The cable sample is deemed 603322-3c pass this test if no fuse was ruptured nor any lamps extinguished during the 3 hour flame application and on re energizing the cable after 16 hours.
If a cable can pass a ic UL fire standard, an UL performance verification mark can be applied onto the cable jacket, illustrating both the UL class and the number. This general purpose cables also meets UL The CMG cable is suitable for use in.
This cable cannot be installed in bundles and must be protected in metal conduit.
Smoke Measurement Systems FTT can supply either laser or white light systems for smoke measurement in compliance with the standard. The Classification utilises the results obtained 6033-23c traditional IEC test equipment fitted with heat and smoke release measurement instrumentation.
In general, the toxicity index of LSZH material is less than 5. General purpose cables meets UL Data logger if purchased. Test for vertical flame spread of vertically-mounted bunched wires or cables – Category B -Installation In one layer front.
The standard is subdivided in several parts that differ one from the other for the quantity of cable to be installed, the installation mode and the flame application time. IEC details a method of test for assessing the fire resisting characteristics of a cable. A single survival category W is defined if the cables surpassed the testing requirement. The minimum light transmission is recorded. FTT can supply either laser or white light systems for smoke measurement in compliance with the standard.
