Result of the test is considered positive if at that time will not be considered a short circuit in the circuit being tested.

We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. The maximum change in attenuation a change from zero is recorded during the burner application period.

Fire Testing

Procedures and requirements — Optic Fiber Cables. 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 optical fibre cables are not given by IEC 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.

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 stresses and water spray.

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 Cables of smaller diameter are intended to be tested using the apparatus, procedure and requirements of IEC The time of the fire is minutes.

Tests for electric cables for fire conditions and shock- Circuit integrity.

TC 20 – Electric cables rss. Procedures and requirements for fire with shock — Cables of rated voltage up to and including 0. 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 with standards, as well the echanical shock of the 5 minutes interval.

Fire Resisting Characteristics of Electrical Cables Apparatus

Result of the test is considered positive if at that time will not e considered a short circuit in the circuit being tested. Related publications IEC Annex A provides the method of verification of the burner and control system used for the test. The test sample provides cable fragment length at least mm.

Bent wire on the U-shaped with a adius equal to the smallest permissible by the manufacturer, is mounted on a metal assay ladder. Do you need a multi-user copy? It is intended for use when testing cables of greater than 20 mm overall diameter.

IEC / IEC Test method for fire with shock

Circuit insulation Integrity in accordance with IEC IEC specifies tests for electric cable for circuit integrity under fire conditions. Procedures and requirements — Cables of rated voltage up to and including 0. The optical power meter is zeroed and the changes in attenuation during the minutes burner application period are monitored. Preview Abstract IEC Our prices are in Swiss francs CHF.

Iev details a method to assess the circuit integrity of optical fiber cables. It is divided in following parts that describe the test modes, the conditions, and the equipment to use. Result of the test is considered positive if at that time will not be considered a short circuit in the circuit being researched. In the 15 minutes period after the flame application, a maximum attenuation is also recorded. Procedures and requirements — Electric Data Cables.

IEC ed 1. It constitutes a technical revision.

The following test report forms are related: The significant technical changes with respect to the previous edition are as follows: This second edition cancels and replaces the first edition published in Requirements are stated for an identification that may optionally be marked on the cable to signify compliance iex this document.
