Cables of smaller diameter are intended to be tested using the apparatus, procedure and requirements of 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. Tests for electric uec for fire conditions and shock- Circuit integrity.

Procedures and requirements — Electric Data Cables. Result of the test is considered positive if at that time will not be considered a short circuit in the circuit being researched.

The maximum change in attenuation a change from zero is recorded during the burner application period.

Circuit (insulation) Integrity in accordance with IEC |FAQ

Result of the test is considered positive if at that time will not e 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. Procedures and requirements for 6033-11 with shock — Cables of rated voltage up to and including 0.


Circuit insulation Integrity in accordance with IEC IEC specifies tests for electric cable for circuit integrity idc fire conditions. Requirements are stated for an identification that may optionally be marked on the cable to signify compliance with this document. It is divided in following parts that describe the test modes, the conditions, and the equipment to use.

The following test report forms are related: 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. TC 20 – Electric cables rss. During the study, through all the cable wires is passed current with ied 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.

IEC details a method to assess the circuit ied of optical fiber cables. The optical power meter is zeroed and the changes in attenuation during the minutes burner application period are monitored. Related publications IEC To better simulate the real fire conditions, with mechanical stresses due to the fall of materials 60331- 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.


Procedures and requirements — Cables of rated voltage up to and including 0. This second edition cancels and replaces the first edition published in Our prices are in Swiss francs CHF.

The time of the fire is minutes.

IEC 60331-1:2018

In the 15 minutes period after the flame application, a maximum attenuation is also recorded. IEC applies to the cables with a diameter greater than 20mm, and introduces the standards nd procedures for testing of cables exposed to oec and mechanical shock equipment according to 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 tested.

It constitutes a technical revision. It is intended for use when testing cables of greater than 20 mm overall diameter.

Preview Abstract IEC IEC ed 1. Bent wire on the U-shaped with a adius equal to the smallest permissible by the manufacturer, is mounted on a metal assay ief.

Do you need a multi-user copy? The significant technical changes with respect to the previous edition are as follows: 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
