The sample method provided in this section is suitable for samples that need to withstand the simulation of complex and mixed excitation vibration tests. The purpose of this standard is to verify that the sample does not experience unacceptable degradation in function and/or structure after being subjected to the specified mixed-mode excitation. When the vibration measurement value of the actual environment has a mixed mode, it is particularly suitable to use this method to clip the vibration environment. This section is also applicable to reveal the cumulative effects of random and sinusoidal and/or random mixed vibration stress, and the resulting mechanical defects of the sample and the reduction of the specified performance. This information, combined with the relevant regulations, can be used to assess the acceptability of the sample. In some cases, this test method is also suitable for verifying the mechanical strength of samples. This section is also applicable to samples that may be subjected to random and/or a combination of random and deterministic vibrations during transport or actual use, such as in aircraft, spacecraft and transport will be packed in transport containers, and the transport containers as part of the sample itself. This part applies to electrical and electronic products, and also applies to other fields that require it.
