GB/T 2423.41-2013 "Environmental testing - Part 2: Test methods - Wind pressure" applies to electrical and electronic equipment and components installed outdoors (such as radar antennas, satellite antennas, etc.), but does not apply to towers for fixed equipment. It specifies the terminology, equipment and sample requirements, test conditions, and methods for conducting wind pressure tests using wind tunnels. The standard clarifies wind tunnel specifications, wind speed levels (including standard values such as 15 m/s and 30 m/s), and angle adjustment requirements. It covers measurement items such as static/rotational force measurement, pressure measurement, and deformation measurement of flexible components. The standard is used to evaluate the adaptability of products to wind pressure and the rationality of their structure, providing a unified basis for the design and inspection of outdoor electrical and electronic products.
