“…This leads to increased retention and absorption of moisture. Khalid et al [34] investigated the capability of relating the quality of a crossarm to the amount of moisture content within a crossarm. Dielectric measurements were taken from sound wood, incipient decay, and severely decayed crossarms.…”

Crossarms are widely used in power distribution and telecommunication sectors to support overhead cables. These structures are horizontally attached to the top of vertically erected utility poles and are essential elements in connecting overhead cables to the poles. Timber is the dominantly used material type for crossarms in the existing distribution networks. Nevertheless, there are alternative crossarms made from steel, composites, polymers, and even from concrete. This paper reviews the studies on the condition assessment of timber crossarms considering the aspects of decay identification and flexural strength assessment. The limitations and shortcomings of the conventional inspection techniques for crossarms are presented. Then, the studies on the developments of non-destructive test methods to address these issues are reviewed. Further, the results from the experimental work conducted to assess the structural capacity of in-service crossarms are presented and analysed. In addition, the possible future advancements of alternative crossarm types are also discussed, considering the mechanical strength, durability performance, and sustainability aspects. This paper aims to highlight the advantages and disadvantages of different condition assessment techniques for crossarms, indicating the importance of an integrated approach combining both the conventional and non-destructive testing techniques.

“…A meeting of the Hayaa in Burayda condemned al-Ghamidi, particularly for venting his ideas through the liberal press. 117 136 The most generous support that al-Ghamidi has received is from more moderate ulama outside Saudi Arabia. The famous Iraqi sheikh, Ahmad al-Kubaysi, living in Qatar, agreed with al-Ghamidi that forbidding ikhtilat has its origins in the Abbasid dynasty and that Arabs during the time of the Prophet and the Rightly Guided Caliphs did not forbid men and women from mingling at the Kaabah, in marketplaces, in education, in prayer and even in battle.…”
