ISO 12494:2017 PDF Download

ISO 12494:2017 is a standard that provides guidance on determining ice load on various types of structures. It emphasizes the importance of considering the applicability of the standard to the specific structure in question. While the document is based on data related to normal icing amounts for specific sites, it acknowledges that in some cases, this information may not be available. However, local meteorologists or experienced individuals can provide estimates of the proper ice class for such cases. Designing for some ice is strongly recommended as opposed to ignoring the potential problems caused by ice. The standard covers structures such as masts, towers, antennas, cables, ski-lifts, and buildings exposed to potential icing. It also mentions that other types of structures can be considered, depending on their sensitivity to unforeseen ice. Although electrical overhead lines are covered by IEC standards, this document can be used for mast structures if desired.
