GB/T 17626.10 - 1998 focuses on the field of electromagnetic compatibility, specifying the test method for the immunity of damped oscillating magnetic fields. It clarifies the test principle, specifies the performance requirements and parameter settings of the test equipment, and standardizes the test layout and operation process, including key links such as test grade division and test duration. This standard provides unified criteria for evaluating the anti-interference ability of products in the environment of damped oscillating magnetic fields for related industries such as electronic and electrical products, helping to improve the electromagnetic compatibility of products and ensuring their reliable operation in complex electromagnetic environments.
