Popis
PD IEC/TR 62048:2014
This standard PD IEC/TR 62048:2014 Optical fibres. Reliability. Power law theory is classified in these ICS categories:
- 33.180.10 Fibres and cables
This technical r eport 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.
NOTE Power law is derived empirically, but there are other laws which have a more physical basis (for example, the exponential law). All these laws generally fit short -term experimental data well but lead to different long -term predictions. The power law has been selected as a most reasonable representation of fatigue behaviour by the experts of several standard-formulating bodies.
