Scope
This standard specifies the test methods for sinusoidal beat frequency vibration of components, equipment and other electrical and electronic products. Because these components, equipment and other electrical and electronic products (hereinafter referred to as samples) will be subjected to short-duration pulse and oscillating forces such as earthquakes, explosion phenomena or machine vibrations during use. In this test, the sample is excited with several predetermined sinusoidal beat vibrations at a fixed frequency (see Figure 1). These fixed test frequencies are either predetermined frequencies or dangerous frequencies identified by means of sinusoidal vibration tests (GB/T 2423.10). There is a pause between individual sinusoidal beats to allow the self-response of the sample to decay. A detailed list of the details necessary for the preparation of relevant specifications is given in Chapter 12 of this standard and is guided by the guidelines in Annex A (reminder).
