This second edition cancels and replaces the first edition published in Our prices are in Swiss francs CHF. IEC ed 1.
Result of the test is considered positive if at that time will not e considered a short circuit in the circuit being tested. The significant technical changes with respect to the previous edition are as follows: Procedures and requirements — Optic Fiber Cables. Result of the test is considered positive if at that time will not be considered a short circuit in the circuit being researched.
Circuit (insulation) Integrity in accordance with IEC |FAQ
During the test, to the wire cores of cable a voltage of the nominal value is applied for telecommunication cables equal to Vthereby creating a closed electric circuit. The maximum change in attenuation a change from zero is recorded during the burner application period.
It is intended for use when testing cables of greater than 20 mm overall diameter. Cables of smaller diameter are intended to be tested using the apparatus, procedure and requirements of IEC Result of the test is considered positive if at that time will not be considered a short circuit in the circuit being tested.
Procedures and requirements — Electric Data Cables.
The test sample provides cable fragment length at least mm. In the 15 minutes period after the flame application, a maximum attenuation is also recorded.
Procedures and requirements for fire with shock — Cables of rated voltage up to and including 0.
The time of the fire is minutes. Details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to metallic data and telecom cables and 60313-1 fibre cables are not given by IEC IEC details a method to assess the circuit integrity of optical fiber cables. Procedures and requirements — Cables of rated voltage up to and including 0.
IEC / IEC Test method for fire with shock
Preview Abstract IEC It is divided in following parts that describe the test modes, the conditions, and the equipment to 60331. IEC applies to the cables with a diameter greater than 20mm, and introduces the standards nd procedures for testing of cables exposed to fire and mechanical shock equipment according to Related publications IEC Requirements are stated for an identification that may optionally be marked on the cable to signify compliance with this document.
Bent wire on the U-shaped with a adius equal to the smallest permissible by the manufacturer, is mounted on a metal assay ladder. The optical power meter is zeroed and the changes in attenuation during the minutes burner application period are monitored. Tests for electric cables for fire conditions and shock- Circuit integrity.
During the study, through all the cable wires is passed current with rated voltage and these cables are subjected to fire during min, where fire source is a gas burner set in conformity 600331-1 standards, as well the echanical shock of the 5 minutes interval.
Annex A provides the method 603311-1 verification of the burner and control system used for the test. Circuit insulation Integrity in accordance with IEC IEC specifies tests for electric cable for circuit integrity under fire conditions. To better simulate the real fire conditions, with mechanical stresses due to the fall of materials and with the presence of water, the testing conditions have been modified by changing the duration, increasing the temperature of the flame and by adding mechanical 6033-11 and water spray.
