IEC 60793-1-33 Ed. 1.0 b:2001, Optical fibres - Part 1-33: Measurement methods and test procedures - Stress corrosion susceptibility

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.
