This standard contains the functional and design criteria for accident monitoring instrumentation for new nuclear power plant designs and design modifications for nuclear power generating stations.

This part of IEC 60793 provides a practical method for evaluating fibre performance in a defined environment.

The purpose of this standard is to determine the suitability of class A multimode fibres and class B and C single-mode fibres to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high humidity at constant temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-78, Test Cab: Damp heat, steady state.

NOTE This test method may be used for other fibre categories if agreed between customer and supplier.

This part of IEC 60793 provides a practical method for evaluating fibre performance in a defined environment.

The purpose of this standard is to define a test that determines the suitability of category A1 multimode fibres and class B and C single-mode fibres to withstand the environmental condition of immersion in water which can occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of immersion in water over a given period. This procedure is conducted in accordance with IEC 60068-2-18, Test Rc: immersion.

Amendment 1

This part of IEC 60794-1 describes test procedures used to establish uniform requirements for mechanical properties of optical fibre cables when subjected to bending under tension. The purpose of this test is to determine the ability of an optical fibre cable to withstand bending around rollers or bows during installation, when a specified load is applied.

This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors.

Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc.

See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide on test methods of all types.
