Die Annotation des Normtextes IEC/TR 62048-ed.3.0 :

IEC TR 62048:2014(E) is a guideline that gives formulae to estimate the reliability of fibre under a constant service stress based on a power law for crack growth. This third edition cancels and replaces the second edition published in 2011, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: - correction to the unit of failure rates in Table 1; - correction to the FIT equation for instantaneous failure rate [19] in addition to all call-outs and derivations; - insertion of a new note about fibre length dependency of failure rates; - addition of informative Annex A and relevant reference; - editorial corrections of inconsistencies. Keywords: reliability of fibre, service stress, power law for crack growth
