IEC 62567:2013 provides test procedures based on the documents mentioned in the introduction and devoted to minimize the causes of discrepancy between test results, taking into consideration the large experience accumulated in the last 30 years by numerous test engineers and available in literature, including a CIGRE Technical Brochure specifically referring to this standard (see Bibliography). This Standard describes the current methodologies, including apparatus, procedures and accuracies, for the measurement of conductor self-damping and for the data reduction formats. In addition, some basic guidance is also provided to inform the potential user of a given method's strengths and weaknesses. The methodologies and procedures incorporated in this Standard are applicable only to testing on indoor laboratory spans. Key words: Overhead lines, Self-damping, Conductors
