IEC 60793-1-3:1995/AMD2:1998

Applies to the tests of mechanical strength, ease of handling or the recognition of physical defects of primary coated or primary buffered optical glass fibres. The methods are to be used for inspection of fibres for commercial purposes.

Describes methods for the determination of stress corrosion susceptibility parameters of optical fibres. Dynamic fatigue and static fatigue tests are used to determine stress corrosion susceptiblity parameters, dynamic n-value and static n-value. Five test methods are described: Dynamic and static n-value by axial tension, dynamic and static n-value by two-point bending, and static n-value by uniform bending. These tests provide values of the stress corrosion parameter, n, used for reliablilty calculations in IEC 62048.
